Science Objectives
Expedition 321 is divided into 2 parts. The first part is the second expedition of the Pacific equatorial age transect (PEAT) science program, which consists of Expeditions 320 and 321, grouped into one science program. The goal of the PEAT program is to recover a continuous Cenozoic record of the equatorial Pacific by drilling at the paleoposition of the Equator at successive crustal ages on the Pacific plate. The second part of the expedition consists of a transit from San Diego, CA to Victoria BC including a cement project at one of the CORK site in Juan De Fuca, and the 2009 School Of Rock.
General Leg Information
Expedition 321 officially began at 0736 hr 4 May 2009 with the first line ashore Pier 2B, Honolulu, Hawaii. The ship arrived a full day early having been scheduled in at 0700 hr 5 May. The early arrival added a bonus day to a schedule that already was planned as a 4-day port call. PEAT II will official end on 0600 June 23 in San Diego. Exp 321 scientists will disembark in San Diego, members of School of Rock, Juan de Fuca cement team, and other IODP staff, both from Lamont and TAMU, will board the ship in San Diego. The ship is scheduled to be in San Diego no more than 24 hours.

Lab Activities
Expedition 321 ran smoothly. Main problem areas include storage in the Hold Reefer and pallet areas, gas bottle arrangement (see LO report), and core rack space in core lab. These issues are being addressed and we hope to resolve most of these issues before Exp 321. Equipment and instrumentation worked well with no major catastrophes (see individual reports). Core flow in lab was smooth (except the minor hic-ups due to limited D-tube rack space but this will be addressed before Exp 321). Physical counts and checking out items from the stores took a bit of getting used to for some of the technicians but they are now on top of it and all items are updated in AMS.
Lab Safety
Gas bottle storage did not provide easy access to the bottles nor the manifold, particularly for the argon. Chemtech require access to turn on/off and frequent connection and disconnection of argon bottles. A re-modification is underway. The plan is bring the manifold out to the front for easy access. A multiple bottles hookup with flexible hose will be a best solution. However, we do no have all the parts to complete this project during EXP321 and the transit. (see special project at the end of this report)
Several safety meetings were held with all technical staff to review regular operation, safety concern, and information communication.
Core Lab
This was the first full expedition that this crew participated in for Phase II IODP operations. There were some breaking-in pains but in general no real hurdles were encountered, items to just think about for the future. A consensus on both crews might have to be met.
One GLARING omission from the CoreLab, which was present in the old CoreLab for many years, and MUST return in some form, is the drillstring tattletale. We basically have absolutely no idea where the core barrel is. Is it coming up? Is it going down? All we have is a Core-On-Deck indicator in furlong units…when it comes to 0, there is a core up. There is a consensus that this is very unacceptable and not knowing where the core barrel is at ANY time makes our daily routine more chaotic than it needs to be.
Paleomagnetics Lab
This was a quiet leg overall, consisting almost entirely of simply running sections through the cryomag. The scientists ran their discrete samples in the cryo and measured bulk susceptibility with the new Kappabridge. Because it was an equatorial expedition, core orientation was a key part of magnetostratigraphic determinations. The new Flexit tools were used very heavily this leg.
Curation
Expedition 321 drilled 8 holes at 2 sites (U1337 and U1338). 297 cores were recovered and split into 1,840 sections. A total of 2,555 meters of core was recovered. All cores were split, sampled, and described with the exception of U1338D. These whole rounds will remain on board for Expedition 321T (School of Rock) and Expedition 323 (Bering Sea) to process as a training exercise.
Down-hole Measurement Lab
APCT3 Deployments were done on both sites U1337 and U1338
One SET deployment was done on site U1338
In total 15 APCT3 and 1 SET deployment were done during this expedition.
Barring one or two deployments, all yielded excellent returns with a high overall confidence in the measurements. The calm sea states encountered throughout the expedition was a contributor to the successful deployments, as was the procedure to have the passive compensator open during the measurement period. This restricted tool movement and very little friction induced temperature spikes were noted. Allegedly this procedure is not followed on the opposite crue. There is a good argument for making it (open compensator) a standard procedure.
TPFit software was used to estimate the undisturbed formation temperature from the tool decay data. APCT3 raw data files were uploaded to LIMS. At the time of writing this report the developers were working on ways to load the SET raw data and TPFit-data to LIMS. All data files are in a folder, 'Exp321 Temperature data' on the DHML PC and backed up on my laptop.
The SET tool deployment was the first for this tool on the JR.
Thin Section Lab
There was one thin section request of a dolomite concretion.
Chemistry Lab
321 was a moderate recovery cruise. We drilled at two sites. Scientists took WRND IW samples on Hole A at each site, and also extensively used the RHIZON technique to obtain additional water.
X-Ray Lab/ICP Prep
The lab processed 13 XRD samples, 141 ICP samples and standards and 35 Carbonate Leaching samples during Expedition 321. The Bruker D4 diffractometer worked well but experienced a few problems with the cooling water system. The Cahn 29 electrobalance experienced problems resulting in procedural and software changes but without a loss of data.
Information Systems
Overall, the information systems aboard provided an efficient method in which to store data from the expedition. Most of information technology related hardware performed well. The software networking, applications and servers had some issues that were corrected or are being corrected.
Developer
The initial science work of Expedition 321 is captured and complete: both in physical material, acquired data, and initial observations. This effort is supported by the personnel and facilities of a multi-disciplinary laboratory environment. Every system has its process and tools. And that's where applications development and database efforts are applied.
James Zhao and David Fackler sailed as the applications specialists for Expedition 321. Developer operational duties include:
•Keep the core flowing (in-so-far as software/hardware affect this).
•Keep the data flowing (ditto).
•Train staff and participants in the effective use of tools and systems.
•Troubleshoot malfunctioning systems.
•Programming. Devise fixes for malfunctioning systems and processes.
•Documentation, communication of issues and fixes.
•Cross-train in the support of the many systems in-use.
When the database specialist does not sail, additional duties are accrued in the context of data management, and data quality.
On-going and frequent feedback from shore were provided by Paul Foster, David Houpt, Peter Blum, Stephanie Zeliadt, Chris Bennight and a host of others monitoring the JR Developer Group email distribution list.
The remainder of the application development and database section summarizes specific Expedition 321 experiences. The material is organized on a laboratory and systems basis. The bias is to highlight systems that have changed or are "broken" and not yet fixed. Where systems are perceived as "broken", a synopsis and way forward are suggested. The stuff that works, just does-we stand on the good work of many before us.
Underway/Fantail
This was my inaugural Expedition as the UW MLS. In some areas it was a learning experience, in others it was getting re-acquainted w/ systems that I had worked w/ before, but enhancements had since been done.Expedition 321 consisted of three transits, two sites and eight holes.Transits: Honolulu to PEAT 7C (L1T)PEAT 7C to PEAT 8D (L2T)PEAT 8D to San Diego (L3T)Sites:U1337 (A/B/C/D holes) & U1338 (A/B/C/D holes)Eight site fixes performed & two PDR depths observedAs was in Expedition 320, no underway watches were conducted by the IODP technical staff, except for occasional monitoring by myself. When on-site, when I was off-shift, ALO Steve Prinz monitored the systems per my instruction. This worked out well.For a reason undisclosed to me, navigation data for Expedition 321 is catalogued in the LIMS under Expedition 320. The Application Developers are aware of this.
The G-gun cluster was used as the VSI seismic signal source at both site locations. There were no problems. Guns were rebuilt and pressure tested during transit.
Image/Photography
The cruise started with a busy portcall consisting of video of ship tours and photographing evening presentations by the 320 cruise participants and VIPs at the Marriott in Honolulu.
The duties of the imaging specialist have changed considerably from the past. Rather than processing film and making prints we now inspect each section image file for accuracy, calibrate imaging equipment when required, shoot close ups when requested, produce public relations and general informational images as well as shooting and editing video.
On this expedition I have done no video since a videographer, Maarten in 't Hout, working for Ocean Leadership has sailed. We will have access to all of the video he has shot during the expedition. This will change after our stop in San Diego when Maarten will depart and the School of Rock and Leslie Peart come aboard. I anticipate shooting video as well as stills for the next ten days of transit to Victoria. I have inspected all of the section images for accuracy, taken close-up core images as well as cruise related and PR images. I also worked the catwalk for core recovery.
Engineer
The challenge on Exp 321 was to get the RIS system serviceable, following the flooding of the Master and Standby PC's in sub-sea and the failure of the Crio Data-box controller during Exp 320. Following the installation in Singapore, some had yet to be expended to customize the system to comply to JR specific needs. A number of sensors were still not working and processes in the system needed streamlining.
Downhole temperature measurements were done from the DHML. Sixteen deployments were made, all returning high confidence data.
Orientation with the Flexit tools was coordinated by Margaret Hastedt from the Paleomagnetics lab and provided generally reliable results.
Special Projects

  • Gas Bottle storage has been re-arranged. Bay #1 and #2 (from port side) are now house Argon bottles. Bay #3 house bottles of Helium, Nitrogen, Oxygen, and MBIO P5.

For Argon gas, the plan is to bring the manifold to the front for easy access. An 8 bottle hookup connection with flexible hose is set up. If this set up works to the satisfaction of the staff, another 3 setups can be purchased and set up during X324.

  • The second Fisher Brand refrigerator is installed in the BHAZ for dry non-hazardous chemical storage. The cabinets inside are re-arranged to accommodate this addition.
  • Emergency shower has been moved into the Paleo-prep lab, eye wash basin outside the microscope lab is removed.
  • Description table was moved 6" toward port side to create more space for the core description.
  • Catwalk; fibergrate shelf under c/c bench, shelf over C/C/ bench backsplash, relocated core back brackets for proper pin alignment, relocated breathing air line.

ASSISTANT LAB OFFICER'S REPORT

Heather Barnes & Steve Prinz
Summary:
Expedition 321 ran smoothly. Main problem areas include storage in the Hold Reefer and pallet areas, gas bottle arrangement (see LO report), and core rack space in core lab. These issues are being addressed and we hope to resolve most of these issues before Exp 323. Equipment and instrumentation worked well with no major catastrophes (see individual reports). Core flow in lab was smooth (except the minor hic-ups due to limited D Tube rack space – this will be addressed with Bill Mills). Physical counts and checking out items from the stores took a bit of getting used to for some of the technicians but they are now on top of it and all items are updated in AMS. The elevator caused several hic-ups and by Captain's order – it is not to be used in Heavy Seas.
Offload summary:

  1. Cores - San Diego
  2. Domestic Samples - San Diego
  3. Flex-it tool and Schlumberger item - San Diego
  4. Foreign Air Freight - Victoria
  5. Surface including gas bottles, -40 freezer, GC, V-brick systems, Schlumberger etc. – Victoria
  6. Personal boxes – Victoria
  7. 4 Refrigerated Sample Boxes – Victoria
  8. 1 Frozen Shipment – Victoria



Specific Items:
Core Reefer:
After much calculation we concluded that the best set up for the space (awkward area) includes removing two fans, building centre shelf and utilizing the core pallet stacker. The main debate was whether dense packing versus packing on pallets provided the most use of the space. Calculations proved that pallet stacking with the use of the electric pallet stacker provided more cores in the area. Total meters on racks = 2760, Total on Floor pallets = 1580, Total = 4340 m. The idea is to stack 7 core boxes high on bottom pallet (total 14 boxes/pallet), then use the electric pallet stacker to move this to the top shelf (we suggest putting plastic banding around the stack for safety – the plastic banding tool is easy to use and will only add another 5 minutes to the process). Then, stack a total of 8 boxes high on bottom pallet (16 core boxes per bottom pallet). When offloading time comes we will have to top up each pallet to 10 high + 1.
Our idea of best utilization of space is to dense pack d-tube boxes on the STBD side and centre shelf. Pack cores first on the Port side. Use the d tubes from the centre rack first. Once the port side space is filled hopefully the D-tubes from the centre rack are used and we can now use the centre rack for cores. The floor in front of the Port side shelf will have to be used for cores as well.
Details:

  1. Why use the Electric Pallet Stacker? – allows us to get a stack of 7 cores on the top shelf. Without the pallet stacker individuals cannot safely stack more than 6 cores high on top shelf. The main downfall of this is the extra step of plastic banding for safety – (you decide if it is needed).
  2. Two fans (STBD FWD and PORT AFT) were removed and stored in the Heavy Tools. These two fans provide the most useable space for core boxes. The column STBD Aft prevented us from using the electric stacker so we decided to leave that fan and remove the PORT Aft, where we can easily use the stacker.
  3. Middle Shelf installed. This configuration provided the most number of cores.


AMS:
Duplicates have been removed. All stores updated. Note: Paint inventory – those paint cans in the Catwalk Flammable Locker and in the Logistics Shop Flammable Locker Upper Tween are checked out (only those in the Bridge Flam are not checked out – where check out sheet is).
Elevator:
It is advised not to use the elevator in Heavy Seas – Captain's order. Steve opened the elevator door on UTS landing twice to find a deep empty shaft before him. In San Diego we had several problems with the elevator preventing us from moving core. As we understand the elevator hits the limit switch on the bottom floor and will not move. You must call an Electrician to fix this error. The solenoid on the Bridge Deck often fires continuously. (I assume this will be sorted by Transocean, John Macintosh is aware and ETs have been looking at it).
Core Splitter:
We are pleased with the performance of the core splitter. The wish list includes an automatic 'return to zero' button. Also necessary is a better spray shield, which I believe Bill Mills is working on. A spacer that fits against the screw stops which lets the wire to cut all the way through the endcaps every time was made – very useful.
Ok to Split Program:
David Fackler has written an SQL script (Oracle) that quickly polls the database to report which sections have valid uploaded data (see core lab report for more details). Type forward slash '/' hit enter, and then type the core number. This is located on the sampling PC. The reported data types are:
GRA1= Whole Round Multi Sensor Logger Grape
GRA2=Fast Track Grape
NGR=NGR
MS476=Fast Tract Magnetic Susceptibility
MS477=Whole Round Magnetic Susceptibility
PWL=PWave Logger
TCON=Thermal Conductivity
We checked for the number of measurements for each section – they should be about equal (except for shorter sections).
Catwalk:
The Seawater pipe/drain flush valve (located on the forward port of catwalk) is planned to be replaced with a more practical valve and the pipe will be turned into the drain. There is also a small seawater pipe there that will have a quick connect for us to use when needed. Transocean are going to complete these items when time allows – maybe not this expedition.
The breathing air piping was relocated from above the core tray/end cap baskets to below. This should prevent hoses from sweeping supplies off of the tray as people move about the catwalk while trailing the air hose. Quick connects are facing down to prevent grit from entering them. The connectors were carefully placed between the core receiving trays to make access easier.
The brackets holding the core receiving tray closest the rig floor have been re-welded to the rail. The original placement was not precise enough to allow the pins to pass through the pivoting rod and into the bracket.

CC Bench:
The location of the CC bench on the catwalk is not ideal, space is tight out there. Steve was jabbed in the back by the handle of the sledge hammer while cutting cores. At times it's difficult to walk past the cc bench if people are working back to back. The high noise level caused by the hammer and the water spray gun make it difficult to converse with catwalk samplers for IW & Chemistry. A suggestion is to relocate it outside downhole tools. What do the rest of you think?
BHAZ:
The extra Chemical Fridge was moved into this room and chemicals stored in the fridge in the chemistry lab will be moved to the fridge in the BHAZ. Extra shelving could be emplaced – but the question is what could we store on the shelves? The fibergrate flooring was removed as it would interfere with cleanup efforts of an accidental spill.
Safety Shower – Paleo Lab:
The safety shower next to the photo closeup table was moved to the paleo lab. It will be easier and safer to maneuver in this area without the obstruction. This prepares the area for future enhancements such as adding a core rack.
Tech Internet PC:
All have agreed that the techs need a dedicated internet station in the core lab to allow for convenient email and research activities. We discussed this with the MCS' (Matt Nobles) and concluded that the core entry computer would be the best.
Technician Shifts:
There was more overlap of shifts than we have had in the past. Besides the traditional 12-12 shift, there was quite a few working 6-6's. We think this helped with continuity of methods and tasks. It also eliminated the frequent tension which grew out of the 2 shift – 'A team versus the B team' mentality. We encourage LO's to continue to schedule this way.
Technician Safety Meetings:
We had a few Staff meetings throughout the cruise to go over shipboard duties, safety issues and concerns, port call duties etc. These were beneficial to bring the technicians together and to discuss any issues they may have. A period of fifteen minutes or less every couple of weeks is a good TEAM building practice.
Special Projects:

  • Moved description bench 6 inches towards the Cryomag.
  • Re-arranged the core description/splicer space in core lab.
  • Moving extra fridge for chemical storage to BHAZ.
  • Labeling of UTS drawers.
  • Hold reefer fan removal and building of new shelves.
  • Fix emergency shower outside BHAZ.


CURATORIAL REPORT

Chad Broyles

Exp 321

Summary
Expedition 321 drilled 8 holes at 2 sites (U1337 and U1338). 297 cores were recovered and split into 1,840 sections. A total of 2,555 meters of core was recovered. All cores were split, sampled, and described with the exception of U1338D. These whole rounds will remain on board for Expedition 321T (School of Rock) and Expedition 323 (Bering Sea) to process as a training exercise.
Samples
Due to the nature of the PEAT project (Exp. 320 & 321), personal sampling was limited to ephemeral studies (IW, microbiology, permeability studies). A total 5,892 personal samples were taken and total of 9,643 samples were taken, including residues generated from the samples on Expedition 321. Most personal sampling will be deferred to a shore based sample party at the GCR in October.
Additionally at the beginning of this cruise we split whole round sections from 320 U1336B. From these split sections, 291 samples were taken for ephemeral studies.
Shipments
Core- 396 boxes of archive and working halves will be shipped from San Diego. The boxes containing whole rounds from U1338D will be left in the Hold Deck. These will be processed on Expeditions 321T and 323.
Frozen- One shipment of frozen Head Space samples will be shipped to Dr. Shinya Yamamato in Japan.
Hand Carry-Bridget Wade and Ann Holbourn are hand carrying their micro-fossil
slides.
Residues
20 boxes of residues will be sent in the refrigerated core box shipment from San Diego to the Gulf Coast Repository (GCR) in College Station. All domestic shipments to scientists will be sent from GCR.
The residue distribution is as follows:
Residue Destination
CARBAll to GCR
PALWashed samples divided between Wade, Holbourn, and Hayashi
Residues to GCR.
PMAGAll to GCR. These will be forwarded to Channell
PPAll to GCR
IWSqueezecakes & pore waters divided between Hathorne, Delaney, Sawada, and Gussone
Thin Sections – Gus prepared 1 thin section of dolomite for Steve Hovan.
Smear Slides – Sedimentologists prepared and described 1,629 smear slides. A list of
these may be accessed though LIMS Web Tabular Report.
For Expeditions 321T & 323
Expedition 321 drilled an additional hole, U1338D. 3 cores were taken from this hole and divided into sections. These will be left on board for 321T and 323 to run through core flow and test instruments (both whole round and section half).
Action Item
Beltran Sampling-Catherine Beltran was allowed to take one 10cc sample per core from U1337B&C and U1338B. This is for a pilot study so she can better refine her shore based sampling plan. This was approved unanimously by the shipboard SAC. Her sample request was revised to include this sampling.
Special Projects
Core wrapping-The section halves were wrapped in Glad wrap for Exp. 321. This is to prevent moisture loss and perturb molding of organic compounds. Working halves were wrapped fully from the sample table. Archive halves have a layer on top that was used for color reflectance. All sections will be wrapped in shrink wrap upon arrival at the GCR.
Splitting table-The splitting table was raised at one end to allow for better drainage.
Sample table-A Glad Wrap holder was added to the sample table.
Sample entry desk-The sample entry desktop monitor was mounted on the wall to allow for more table space.
Problems Encountered
Core reefer-The core reefer is inadequate for D-tube storage. We were lucky in the fact that this is a low recovery leg. We experienced problems with stacking and/or palletizing core boxes. The working and archive boxes are mixed up and will remain that way until the end of the cruise. Before we get to San Diego, we will need to separate working and archive boxes before offloading (i.e. re-palletize). If the D-tubes had not been stored in the reefer, this could have been prevented by stacking working and archive boxes on the starboard and port sides of the ship respectively. Modifications to the reefer will be made on 321T. There is a plan to remove 2 of the fan units which will free up some space. A suggestion has been made to store the D-tubes on the F-deck landing aft of the Thin Section lab.
Section Half retrieval from the Core Reefer
We kept core retrieval from the reefer at a minimum for Exp. 321. This was accomplished by carefully working with the describers and the imaging specialist. These individuals double-checked image and color reflectance data on archive halves before they were boxed and taken to the reefer. I also tried to ensure that all necessary samples were taken from working halves before they were taken to the reefer.
Computer Software and Hardware
LIMS-Problems still persist with the LIMS database. At times is very slow. It seems to be running too many processes at one time. This has a drastic effect on the Sample Master (sample input) system. Sample Master will drag as a result of LIMS acquiring too much data at once. I feel this is also the reason Sample Master sometimes does not successfully upload all samples that have been input at the sample table. Features added by Stephanie Zeliadt during Exp. 320 to Sample Master and LIMS Web Tabular Report (sample data retrieval) have been very useful. Please note: No changes to Sample Master or LIMS Web Tabular Report have been made on this expedition since Stephanie was not onboard.
Whole Round Track System Data Verification-David Fackler wrote an excellent SQL script (Ready to Split) that checks the data collected on whole rounds. This script is on the Desktop of the Sample Table entry station. First, double click the icon, "Ready to Split". The user then types "/" and is prompted to enter a core number. The user then enters the core number and all whole round data that have been collected for the specified core are displayed. Important values to ensure have been recorded are, GRA1, GRA2, NGR, PWAVE, and MS. For each complete section half (i.e. 150cm) these values for each core should be similar. In order to change the site and hole you need to go
to Desktop/CuratorApplications/lw_ready_to_split.sql In this text file change the site number and save.When you open the interface again it will change the site/hole.
SMCS System-I feel changes need to be made to the Sample Material Curation System (SMCS). The current setup of the system is confusing. A committee including John Firth, Phil Rumford, and I needs to be organized on shore to review the system.

CORELAB TECHNICAL REPORT Erik Moortgat, Zenon Mateo & Maxim Vasilyev


This was the first full expedition that this crew participated in for Phase II IODP operations. There were some breaking-in pains but in general no real hurdles were encountered, items to just think about for the future. A consensus on both crews might have to be met. Summary Catwalk

  • The catwalk protocols worked admirably. It sure is nice to have more surface area out there.
  • The new core splitters are a nice addition, just a few broken blades.
  • It became obvious that the core-catcher bench is located in an awkward place. It causes a problem for people moving about and the noise can be very uncomfortable at times. A couple of us suggested that it be moved aft of the lab structure, under the stairs but whether that is feasible or not will have to be discussed.

CoreEntry

  • Flow in the core entry area worked quite well.
  • A couple of times we had to place a few cores in the over-flow rack (beside the main rack) but it never got worse than that. We would like to see the vertical spacing between the core dividers lessened so more core dividers could be placed in the rack.

Cutting room

  • A consensus amongst the Techs that the new splitting table is a nice addition. The usual breaking of blades and wire but it seemed at a lesser frequency than the old splitter.
  • It would be nice if the carriage had an automatic return to its home position. For safety reasons there could be a console button that could be pressed when the section is removed from the tray and all hands are clear, sending the carriage home. Like Kristin reported on Exp320, this would facilitate the splitter (Technician) to get another section and not have to wait until the joystick is used to manually send the carriage home.
  • There was a bit of a learning-curve in cutting the harder sediment cores (ex. XCB) w/ the super saw. Also like Kristin reported, if you go too slow the cores cave and a ridge forms along the length of the section but then again you cannot go too fast and torque-out the motor.
  • Etienne had to cut a make-shift block to place between the section and cylindrical tray stops because the travel of the splitter was not long enough for the wire to completely travel through the section. Maybe something more permanent will have to be designed.
  • Bob and Gus worked on raising one end (port) of the splitter's bathtub to help w/ drainage but it is still obvious that work still needs to be done in this area. Either the end needs to be raised more, the other end lowered or another drain installed on the port side of the bathtub. When cleaning XCB cores, quite a mess occurs and better drainage will help alleviate this problem.
  • On the splitter, when the carriage (rollers, blades, wire) come in contact w/ the section, the top end is forced up and this sometimes causes a problem. Either the split is not level, it is wavy or the section is even forced up and over the tray stops. Bill Mills will need to look at this.
  • There is a serious drainage problem around the Felker saws. When cutting discrete pieces, the water level builds up all around the tray and does not drain at all. Makes a huge mess. More drains need to be installed.
  • Be aware when cutting core catcher sections with the super saw. If it's too short, there is a tendency for the split halves to be thrown around inside the enclosure and block the motion of the saw. If this happens, the operator should feel a resistance in moving the saw and should stop immediately until the block has been removed. Right now, the back plexy glass panel has the lower bolted corners broken and are only held by glue and duct tape.

D-tube racks/boxing of core sections

  • The current configuration for the boxing of cores is not ideal, to say the least. The placement of the d-tube racks in the splitting room for the working sections and near the elevator for the archive sections works out (okay) but there are problems encountered in trying to box the cores in the wax boxes on the cart. There isn't enough room, we get in the way of the scientists and it is difficult to maneuver the d-tubes into the boxes. Storage space is also an issue, basically being able to only store about six d-tube boxes in the core lab (on top of the racks and under the description prep area). Storing some in the microscope lab is not ideal as they become in the way for the science participants walking in the area. Storing wax boxes and d-tube end-caps is okay but could be improved upon. Also the staple gun/hose gets to be in the way of the science party participants walking around and could be tripped over (even though it is BRIGHT orange and very obvious).
  • We had quite a bit of problems w/ some of the wax boxes. More often than not the d-tubes had to be forced into the boxes (they were not wide enough) and this caused problems either because the boxes were splitting open along the staple seam or one of the technicians could possibly be injured trying to force the d-tubes into the boxes.

Core flow

  • We were struggling at times w/ certain core flow aspects. Near the start of the splitting process for the U1337 cores (our first site) we were told (unsure by whom exactly...just a placard identifying such) that we had to wait to split a core until ALL the whole round data was uploaded into the LIMS because in a very few instances, the wholeround has to be re-scanned if the data is incomplete or not uploaded.. So for each section (over the length restriction and when the sensors were on) data for the GRA, MSLP, PWAVE, NGR and TCON analyses had to be transferred to the LIMS in order to commence splitting. In the beginning it was difficult to get used to this protocol because time had to be taken away to perform a web query for each analysis, notwithstanding that the uploaders at times would bog down and a number of minutes would pass before a file was successfully uploaded. On a higher recovery Expedition this protocol, in its current state, could cause problems. NGR data also had to be massaged and uploaded to the database which was very time consuming and impacted core flow as well. But everyone got the hang of it and David Fackler wrote a nice little SQL script that when run would prompt for a core number and you would just have to make sure that all analysis were complete for the core sections before splitting. At times, the science party participants would have to wait until all sections were processed before being able to describe or sample. At times a little more patience from them would have been nice.This is the SQL script (it resides on the desktop of the sample station): set pagesize 50000set linesize 160column label_id format a25column analysis format a10select * from (selects.label_id, t.analysis, t.test_number, t.instrument, count(r.result_number), s.x_sca_depth_topfromsample s, test t, result rwheres.sample_number = t.sample_numberand s.sample_number = r.sample_numberand t.test_number = r.test_numberand s.status in ('U', 'P', 'I', 'C', 'A')and t.status in ('I', 'P', 'C', 'A')and r.status in ('E', 'M', 'A', 'N')and s.sample_type in ('SECT', 'SHLF')and s.x_expedition='321'and s.x_site='U1338'and s.x_hole='C'and s.x_core='&core'and t.analysis in ('GRA', 'MS', 'PWAVE', 'NCR', 'NGR', 'TCON')group bys.label_id, t.analysis, t.test_number, t.instrument, s.x_sca_depth_top)order by 6, 2, 4/
  • With having three to four science party participants processing archive halves (prepping, running through the image logger & section-half MSL and describing) they went through the sections quite a bit quicker than before (in the older JR corelab configuration). I think it is a combination of the new loggers and description software. Very impressive.
  • It became obvious that the NGR computer station is in an awkward spot. Either the station must be moved to a better location or at least the monitor, keyboard and chair. It is difficult to carry cores from the racks to the splitting room w/ its current configuration.
  • Observed that the science party participants have to be more diligent in participating in their assigned sampling shifts. Numerous times the Technicians had to round them up to take their samples because the sections were ready to be wrapped and placed in their d-tubes because a new core was ready to be split.

Misc

  • Moved the Stratigraphic Correlator station to the port-side of the aft work area. They felt it would be a better area for them w/ the describers using the smear slide prep area quite often. The two describer stations were thus placed on the starboard side. I still find them quite removed from the whole-round loggers where a good majority of their time is (or should be) spent. Aside from putting them at the thermcon station, there are not many places for them to relocate to.
  • Moved the VCD tables about six inches to port to facilitate a better traffic flow for the describers at that station and the loggers. Works quite well.
  • There was (is still) quite a bit of confusion as to what uploader we should be using at a particular station. At the beginning of the Expedition we were told to use the C# uploaders but when it came time to production a majority of them would not work at all. So for those we switched to the Java uploader and they performed a bit better. Some stations have multiple versions of some uploader and we have to absolutely standardize this protocol. We don't care if it is C# or Java, just have one on the station that works! Special Projects:
  • In addition to the routine IW/headspace sampling done on the catwalk, we were taking microbiological samples (KAL) at the location of the IW sample (opposite on the top of the section) on the APC cores. This sample was the first to be taken and it took the dedicated time of one corelab technician (special clean spatulas, syringes and vials had to be used) to take the sample. After the sample was taken on the catwalk, it had to be transferred to the chemisty lab and placed in the refrigerator. I really don't think that catwalk core flow was impacted too severely by this protocol (especially the time taken away by a Technician) but during a higher recovery Expedition, samples like this might be better suited to be taken by a science party member.
  • A new sampling protocol was used for a number of cores in the A-hole of each site. The chemists took water samples using a procedure known as Rhizon sampling. For the sections being sampled, no acetone was allowed to be used on the bottom end-caps, until after the sampling was done. The end-caps (with a center hole drilled prior to placement on the section) were taped and the sections were placed in their normal position to be scribed and labelled. At this time the chemists inserted a cylindrical rod (ceramic?) into the hole in the bottom end cap and water flowed into a syringe. It worked quite well w/ quite a bit of water collected each time. When the sample collection was complete, the bottom end-caps were properly put on w/ acetone. Our time was not really detrimentally impacted by this protocol but on a high-recovery Expedition it might be tough to fit this sampling method into the flow.
  • Three cores at site U1338D were drilled for the School of Rock to play w/. The sections were scribed and labelled but left whole, available to run though the loggers and split for the teachers.



WHOLE-ROUND MULTI-SENSOR TRACK (WRMST) AND SPECIAL TASK MULTI-SENSOR TRACK (STMST)


Expedition 321 MLS and Developers
Summary
The tracks also performed smoothly during the expedition. All sections, except for the core catchers, were measured. Fractured whole-rounds with extra liner patch were also too big to go through the MS loop and were measured only using the GRA density and PWL. Measurements were done at intervals of 2.5 cm for the WRMST and at 5 cm for the STMST.
Below is a table of the number of sections measured for each instrument and track system

Equipment Performance Summary
These two tracks performed continuously very well throughout the entire expedition. Only a few minor bugs were detected

  1. Data file couldn't get uploaded due to failure to authenticate username and password. This was critical when the data from the first core of U1337B had to be plotted and correlated with the previous hole. The workaround was to re-scan the entire core using a different username. This was after attempts to manually change the registered username in each of the files and re-uploading them. Future developmental work and implementation are needed to resolve this issue.


  1. The resultant velocity from the PWL-PWAVE was noted to be around 1.43 km/s instead of 1.49 km/sec. However, this could be attributed to several factors such as variations in core liner thickness, which could also be different from the constant that is used in the calculation. Despite this difference, users should always be aware of a systematic error in the calculation and should adjust values accordingly during interpretation, which is mostly qualitative anyway, mostly looking at trends and not so much on absolute values because of the inherent alteration of the material during the coring process.


  1. Persistent but minor bugs:
    1. Do not start scanning with section zero; always with section 1, else, the pusher will not go through with the entire length of the section.
    2. On rare occasions, users have reported that the pusher goes beyond the laser or forward limit switch and hit the GRA housing. In such cases, abort the run and bring the pusher to home using the appropriate functions under the Motion Control Menu in the main window.


  1. In one instance, the PWAVE clamped onto a core and would not disengage. It is not clear whether the shuttle was still attempting to push the core or not. This caused the software to hang and had to be re-started. This incident affected the data file generated for the section that was being scanned: two of each GRA and PWL files were created, the second being a continuation of the previous but with an 8 cm gap of no data in between. Also, the second file has mostly repeated offsets and values in them. The test and results were cancelled in the database and the section had to be re-scanned.

Lessons: (1) Always check the data files after every incident that requires re-starting the application. (2) Always check the data files before splitting, not just for completeness of tests but also note the number of results, possible replicates and possible reasons. A sequel query has been written to list the tests and number of results by section for a particular core.

  1. Potential time saving process as suggested by one of the users is to explore making the three instruments in the WRMST measure simultaneously instead of the GRA measuring first and then the MS and PWL together.


  1. There were four instances between the WRMST and STMST when the data file for an instrument was not generated for a section.


  1. The Physical Properties scientists were quizzing us about an odd offset of about one count on susceptibility for site U1338C, cores 12-13 for example. It was particularly noticeable because of the overall very low susceptibility values of the cores measured on 320/321. After some discussion about how the meter is zeroed (at the beginning of every core) one of the scientists noted that they were not always completely careful about removing the water pusher standard at the end of the core's run. The diamagnetism (i.e. negative susceptibility values) of water could account for the ~1-count offset if the water standard was still in the loop when it was zeroed at the beginning of the next core. In short, be sure the water pusher is removed from the loop at the beginning of a new run!




NATURAL GAMMA RAY (NGR)

Maxim Valsilyev

Exp 321

For the entire expedition 321, there are about 1,806 sections measured for natural gamma radiation.
There are set of rules one need to follow in order for the NGR system working smoothly.
As we followed these rules exactly, we had now actual problems with the system during Exp. 321.
1. At the beginning of each shift, check 3 numbers from the CAEN "Squad Scaler and Preset Counter Timer" NIM module (see Fig.) and write them down into NGR_LogBook.txt (find shortcut to that file in the upper left angle of NGR computer desktop). Check numbers with core section outside NGR.
Rule explanation: These 3 numbers represent how NGR system is working.
Top one represents total counts per second in NGR plastic detectors (active shielding). It should be somewhere between 500 – 900. Number in the middle represent counts per second from all NaI detectors (main detectors, which employed to measure core section itself).
It should be between 400 – 900.
Bottom number represent coincidences between plastics and NaI detectors. When such coincidence occur, system do not write information from NaI detectors and it exclude events originated not from the core section, but from from highly penetrative cosmic radiation.
Number should be between 40 -90.
If any of these numbers is out of it range - something goes wrong and you will need seek for advise (most probably from the shore).
During previous expedition these numbers was not checked and it was not noticed that after power failure active shielding somehow was not switched back ON. As a result during the whole month data was taken and reduced without working active shielding. Data base was populated with invalid data and it take ~ 2 weeks to recalculate data, clean database and put back corrected data. Quality of data without active shielding is significantly lower.
These 3 numbers written in the file at the beginning of each shift will give possibility to make quality control after expedition and make it much more easy to correct the data if it will be found necessary
2. Require from the Assistant Lab Officer and/or Curator you working with to cut last 2 core sections of the core as even as possible. Let say if after 5 core section was cut each 150 cm long and you have left 200 cm from the core, section 6 and should be 100 cm long each, but not 150 cm and 50 cm.
Rule explanation: NGR delivery system has problems with delivering light objects (short core sections) into the system. The longer core section is, the less probability for problems to appear. Usually they start after you go below core section length ~ 80-90 cm.

3. Core sections shorter than 50 cm and core catchers are not allowed to enter NGR.
Rule explanation: Such short core sections and core catchers will not only greatly increase risk of the delivery system malfunction, but will be treated incorrectly by data reduction software. Additionally to that, core catchers are too disturbed to carry any reliable information. Anyhow, even if you will measure such short cores and/or core catchers, we will need to remove such data from the database after expedition. So, don't waste time for them.

  1. When you measure a short core section (below ~ 100cm ), and after you press the button "Run Experiment" and the delivery system finds the top of the core you will be asked if the door is completely open. Press "Yes" and put you hand on the core section. After you feel the belt pulling boat start to pull strongly inside the NGR, gently remove your hand from the core section.


Rule explanation: Program asks motors first to rotate slowly to take out the slag from the belts. Such slow rotation will continue as long as belt tension will not become bigger than some threshold value. After it motors will rotate fast to pull boat with core section inside NGR. In case of short (it also means light) core section - tension can never became higher then threshold value and motors will continue very slowly pull boat inside and after some distance delivery system will malfunction. Your hand on the top of the short core section increase belt tension and program works correctly.

  1. When measure short core section place immediately after it short liner with low background lead in it. Fill the rest of the boat with foam.


Rule explanation: Short liner with low background lead makes boat more heavy, which helps to reduce probability of malfunction. Low background lead and acrylic liner very low in internal radioactivity and do not add much to the background. Anything else instead of the short liner with low background lead will increase background up to unacceptable level. Remember that you are measuring cores from under the sea floor. Usually they are at least 10 times less radioactive then normal material which surrounding us on the shore (and on the ship). So, do not use any short concrete cores – it will kill all data for the short core section placed with it.
Placing short linear with low background lead immediately after short core section helps the delivery system take boat out of NGR without malfunction. When boat just appear from the NGR it is still driven by the motor installed under the from door. But after a wile (let say when aprox. Half of the boat is outside the NGR) it stops to pull the boat out due to it position and it is only motor "Z" installed under the outside rails pushing the boat out. Weight above it helps maintain good contact between motor belt and belt connected under the boat. From here comes next rule:


  1. When short core section come out of the NGR put you hand on the short liner with background lead to increase even more contact between motor and boat belts.


  1. Once per day (shift) apply silicon lubricant to the aluminum rails between the outside NGR rails.

Rule explanation: Due to the belt under the boat imperfections, while very rarely, but from time to time, boat can stop moving while loading into the NGR. Applying the silicon grease reduce such stops to ~2 weeks.
Warning: After you will apply the grease the friction between the boat and rails can become so small, that even on long cores the belt tension may be will not overcome limit, when the motors take slag off in slow rotation. For first few cores, after the lubricant was applied, put you hand on top of the long core also.

  1. Additionally to the NGR Core Analyzer software start WSDK program and from it start Terminal application. In case if boat was jammed on its way in or out of NGR write in up-left column of Terminal ST (press Enter) for Stop for motors. After it write MO (press Enter) for motors off. Now you can SLOWLY pull boat out of the NGR. Write SH (press enter) for Servo here – it will clean error status from the Galil amplifier and motors will detect their current positions. Take the excessive slag out of the belt manually by slowly pulling the belt going to the reel under the front door. Exit NGR Core Analyzer software. Start it again and continue measurements.


  1. Wait at least 3 hours after the core was extracted and before you will star to measure core sections from it. NAI detectors not aloud to be exposed to any thermal shock. Do not allow any water or mud inside NGR. The same story – NaI detectors very hydroscopic and will stop to work if any humidity will enter under their housing. Wipe each core you place in the boat. Wipe boat from time to time if you see even smallest drops in it.

Always close doors on the core deck if they are open unnecessary long. Ask everyone around you to keep doors open as short as possible.
10. Do not try to change or improve anything in NGR hardware/software or electrical system (for instance: do not change High Voltage on the detectors, do not attach anything to the NGR frame or change electrical shielding on the nearby loggers, as it will change grounding loops and expose NGR electronics to the extensive high frequency noises we have, due to the step motors, around NGR). Without deep understanding in the system you will easily make it malfunctioning for months!
All these rules are very simple but ABSOLUTELY necessary to follow. If you will do it, I am sure, you will have an easy and successful work with NGR during your expedition, the same as we had during our Exp. 321. Good Luck!

Exp 321T

During transit after Exp. 321 new delivery system was installed. It's description can be found somewhere else. In my previous report I mentioned 10 rules one should follow to successfully work with NGR. New delivery system made rules #4 to 8 obsolete, while other rules are still valid. Here I want to give an example for rule # 10.
During transit some electrical work was done to the many of core deck loggers. During that work, somehow, the grounding for the additional electrical shielding on the MST logger, which is neighbor to the NGR, was compromised. It immediately brought back huge high frequency noise, well above the thresholds of NGR electronics. Few people hunted these noises down for 4 days and finally, only after the global electrical screen was build between the MST and NGR we was able to suppress noise well below the NGR threshold limit.
Do not compromise in any way groundings and electrical shielding of both NGR and MST! Otherwise you will loose ability to work with these 2 loggers simultaneously for the rest of expedition!
Due to the appearance of the new delivery system, corresponding software was modified.
It looks that it is working really good. But keep in mind that as any new software it can have bugs, which you will discover during your work with NGR. Don't be surprised.
One effect which we found so far, is that MCB Configurator somehow changed NaI detectors sequence. It is not clear right now what was the reason for it – new software or may be it just can happen when MCB Configurator searching for the detectors after power switched back after shutdown, or after new USB hardware was added (may be even temporarily) to the computer. I recommend you to check MCB Configurator after each of these events and from time to time during normal, smooth, NGR operation.
I also want to mention here that for the coming expedition you can use background files stored at:
C:\data\ngr\.config\background\Transit after exp321_07.01.2009
And calibration files:
C:\data\ngr\.config\calibration\transit after 321
All these files was measured on July 1 and July 2, 2009 near Victoria, BC.
Calibration files are good for both background and sample, as long as you will not have any major change in the system.
If you had power shutdown you will need to make calibrations again and apply them to all sample files you will obtain after it.
If you have changes in the system configuration –let say after power shutdown you lost active shielding and for any reason you can not bring it back, then you will need additionally to the new calibration, also measure new background with that new configuration. New calibration you will apply now for both – new sample files and new background files.
If you will have time, I am strongly recommending you to measure new background, when you will arrive to the Bering Sea. That area is much more to the north, then Vitoria and it can increase your actual background on 10-20 % easily.

THERMAL CONDUCTIVITY

Margaret Hastedt
For expedition 321, there are 86 sections measured.
Thermal conductivity tests were run routinely on cores from hole A of sites U1337 and U1338. As seen on Exp. 320, the TK04 had a lot of difficulty picking results from most of the extremely high porosity (upwards of 80%), low density, well-drained carbonate and nannofossil/diatom oozes. Better luck was had on the XCB cores of these sites but automated results were still spotty.
The following is a brief explanation of how the LIMS uploader was modified to generate thermal conductivity values in the absence of TK04-generated results (from Stephanie Zeliadt, developer):
"The values that are not present in the thermcon files are being calculated by the uploader. When the thermcon stopped calculating values during the last expedition, in order to get the values they needed, one of the scientists came up with the function necessary to calculate the values. This, however, does not account for the drift factor and it is only calculated in the absence of a value from the thermcon device. The logic is as follows:
Read the corresponding .dwl file.
Values are computed for every two lines of the file according to the following equation:
tcondat = (heatPower / (Math.PI * 4)) * (delta of natural log of time / delta of temperature);
Then the average of those values is computed to determine the final value."
Number of measurements: 264 (including repeats)

SECTION HALF MULTI SENSOR LOGGER (SHMSL) AND SECTION HALF IMAGING LOGGER (SHIL)

Expedition 321 MLS and Developers

Exp 321

Summary
The loggers performed fairly well during this expedition, imaging all sections and measuring the reflectance on all sections except the core catchers. For the entire expedition 321, there are 2,108 sections imaged with additional 129 sections from Hole U1336B. For the SHMSL, 1,823 sections were measured at a resolution of 2.5 cm.
Towards the end of the previous expedition (320), the reflectance instrument was changed from the Minolta to the Ocean Optics spectrophotometer for the SHMSL. The point-source magnetic susceptibility sensor was also disengaged. The Ocean Optics instrument has provided reliable enough reflectance data for downhole analysis vis-à-vis the line-scan images generated by the SHIL. The LED light source was changed once during this expedition. A recurring issue is that the integrating sphere sometimes fails to reach the surface of the section half; observations, potential causes and solutions are described below in detail. Images generated by SHIL have been to user's satisfaction.
Participants. The core describers were mainly responsible for running the SHMSL and SHIL, after the archive halves have been split and cleaned in the archive table.

Equipment Performance Summary

  1. Bugs
    1. SHMSL Problem: IS doesn't reach the SH surface when there is a wide gap or empty space at the top of the section which is outside of the range of the laser. Somehow, the value (NaN?) confuses the calculation (averaging?) of the distance to the surface. This results in the arm getting lost between the home and reverse limit switches. Solution#1: (1) Turn the motor off and push down the IS arm to below the home switch. (2) Cover the void or gap in the section with a piece of paper. (3) Re-scan, allowing the laser to scan the paper instead of the gap. (4) Remove paper immediately after laser scanner passes.


    1. SHMSL Problem: IS doesn't reach or falls a little bit short of the core surface. Follow-up development: Check the averaging function. Before, it was suspected that the IS arm is reaching the hard limit and cannot reach the core surface. However, even if the section is propped-up with an extra half-liner underneath, the IS still would be a little bit short of the core surface. Other observations include such incident occurring during the scheduled time for calibration.


    1. SHIL issue: After an extended time of not being used, the lights will not turn on when the track moves. Solution: Let the scan go through but discard (not save) the resulting image. Before re-scanning the second time, select manual "Turn Lights On" under the Controls menu. To avoid re-scanning, just invoke the function at the beginning of each shift or after an extended time that the logger has not been used.


    1. All Loggers/Tracks: Microscan will not scan. Solution#1: Change "ink" for label printer.


    1. All Logger/Tracks: Selective upload of files. Some files upload, others don't. Solution: Logged-in user is not authenticated. Multiple authentication files? Incompatible authentication files with LIMS?


  1. Software enhancements
    1. Resurrect feature that determines if the bulb is close to needing replacement. This features measures the time it takes to attain maximum counts during the calibration process and compares it to an average time. However, calibration is only done once per shift or every 24 hours, and the bulb can fail quicker than that. Therefore, a more frequent check needs to be implemented.


  1. Others
    1. In the SHIL, application will not display scanned image for saving. Cause: hard drive is full; need to free up some space.


Exp 321T

We wanted to address the problem of the Ocean Optics integrating sphere not being able to touch the surface of sections that are well below the "normal" split surface height. It happens because the integrating sphere's mounting arm bottoms out at the base of its little elevator. We had two choices: either raise the entire track platform and rails, or lower the position of the integrating sphere. We decided to lower the sphere. First a new arm was fabricated out of plexiglass, but it wobbled unsatisfactorily when the track was moving. Subsequently the original aluminum arm was reinstalled and a plexi extender plate added to lower the sphere. Motion control parameters were adjusted accordingly in the software for the new arrangement.

MOISTURE AND DENSITY (MAD) MEASUREMENT

Erik Moortgat
Equipment Performance Summary:
Upon boarding the ship in Honolulu, three (cells 3, 4 & 6) of the six pycnometer cells were inoperable. I knew of cells 3 & 4 having issues but I did not know about cell 6. Thomas Gorgas could not tell me why it was out of commission so I was a blank on this one. While in port, I performed a quick calibration on cells 1, 2, 5 & 6. Cell 6 gave an immediate over-pressurized state, leading to a program abort. Coded into the software is a safety check. Every time a pressure reading is taken, this value is compared to a safety pressure. If the value is exceeded, the inlet solenoid closes and the expansion and vent solenoids open, releasing the pressure in the system, protecting the pressure transducers. Problem identified.
In working w/ Jurie Kotze on troubleshooting our problems, he noticed some very interesting behavior. As previously seen during his troubleshooting efforts during Exp320T, the pressure supplied to the pycnometer cells is actually closer to 26psi instead of the inlet gauge reading of 20psi, which should be the maximum pressure into the system. All pressure transducers show a voltage of 6.2Volts at max (the transducers are rated for a max of 20psi (5V)). This means that we are operating outside of our linear range. The maximum reference is now set at an "out of band" (non-linear) level and once the expansion valve opens we move back into the linear range again. This will definitely give us inaccurate readings apart from the fact that we might damage the transducers as well. So we made adjustments to the helium inlet pressure so that the maximum voltage reached is just below 5V and the software ramps up the pressure inside the sample chambers to 18psi instead of the prior 19.5psi. These values are changed in the following two vis: (cell#_purge.vi and cell#_acquire_pressure2.vi). It was also thought that the higher pressure that we are operating under does have a role to play with the operation of the solenoids (inlet, expansion and vent) as well, as they would battle to open against this higher pressure and this manifests in the behavior of sometimes opening and sometimes not. The cells ran great after these changes were made.
Cell3 was still exhibiting an atypical response in that the voltage at the pressure transducer was a constant 5.6V. I decided to switch the analog inputs on the connector block as a test. This fixed the problem. AI16 on connector1 appears to be faulty so the new analog input for cell3 is AI17 (PT3 (plus) is 66 and PT3(minus) is 33).Jurie was still concerned about cell4's state, he observed behavior indicating a solenoid leak so cell4 was left out of commission for the remainder of the Expedition; to be used for spares if need be.Cell6's behavior is a little more troubling. It appears to calibrate fine (standard and expansion chamber volumes look good) but when a calibration_verification is performed, it is consistently high (from around 4% to a max of 12%). This erratic behavior gave enough alarm to keep it out of commission for the remainder of the Expedition.We sent in a request for spare solenoids and also discovered that a complete cell is coming out to replace one of the inoperable ones. Hopefully cell 4 or 6 can be repaired and turned-around in a timely manner.
Helium supply bottle had to be replaced once during the Expedition.The circulating water bath was extremely filthy at the start of the Expedition. It must be cleaned at least once an Expedition. Using DI water for the duration of the Expedition seems to have kept it cleaner. During either the transit to San Diego or Victoria, a cleaning solution will be used to clean the hoses. This solution is the Cole Parmer Micro-90 solution that is kept on the inventory list.The water bath was set to 27 ºC for the Expedition. Measurements summary:
There were a total of 617 samples taken for MADC analysis this Expedition from the U1337/U1338 cores. They also took 55 samples from the left-over U1336 cores and ran the MADC analysis on these as well. During Expedition 321 we recovered about 2589m of core.They consistently cycled the calibration spheres through the cells during their routine analysis. No obvious slow-downs were observed because of this, even w/ four cells operational. calibrations verifications: cell 1: 662cell 2: 557cell 3: 753cell 5: 554Each time a calibration was performed, it was done not out of need because some filter was exceeded but because some physical aspect of the system was altered (ex: inlet pressure, bottle change). Was astonished at how well the system performed. Before the inlet pressure was changed, between calibrations, the average percent difference between the measured sphere volumes and the actual sphere volumes was:cell 1: 0.2% min & 5.03% maxcell 2: 0.25% min & 0.82% maxcell 5: 0.14% min & 2.01% maxAfter the inlet pressure was changed, between calibrations, the average percent difference between the measured sphere volumes and the actual sphere volumes was:cell 1: 0.26% min & 0.79% maxcell 2: 0.04% min & 0.36% maxcell 3: 0.06% min & 1.52% maxcell 5: 0.15% min & 0.26% max

Scientists' responses:
After all of the MADC samples were analyzed, I asked the Physical Properties scientists for their opinions on how the pycnometer system worked for them, things they liked and aspects that they didn't or felt needed change. These are their responses (summarized):
-When we hit the SAVE RESULT button sometimes it saved the data into the LIMS, sometime it didn't. (comment: this is the first that I have heard about this problem. EAM) Moreover, there is no way I can find whether the save button is hit or not. Can you make some adjustment in the software so that the button becomes inactive after it is hit?
-If I want to rerun some samples, in the current setting I cannot because the sample ID is no longer in the database. Can we have some test ID which can be used to rerun the sample?
-Although there were some issues, I felt very useful about this system, no stress. WAHOO!
-It is very easy to put samples in rather than Quantachrome.

  • Some consumables may be useful: : cotton gloves for handling the cell inserts and standard spheres : air duster to blow dust out of the cells.
    -Sample text ID was not useful and we have been using only the container number to track the samples. It is better to present the sample ID in the sample table selector, such as site-hole-core-section-interval.
    -If the user did not click the save result button and subsequently clicked the select samples or exited the program, even if the user does not want to save the results, a short alert message to remind them would be helpful. It should have both OK and Cancel button.
    MAD service program:-What does the program wait for after starting the program for 1~2 minutes?-Sometimes the program passed on the calculation for a sample although the volume had
    already uploaded. If this phenomenon occurred, I started the program again.
    Balance software:-We sometimes forgot to click the save button before we became familiar with. An alert
    window would be helpful if a sample is assigned and the user did not click the save
    button, but the user did click the search button subsequently.It seems the bug is fixed that final mass value was changed after clicking search button.Sample Master: The container number must be printed on the sample label.

    Equipment Performance Summary
    Bayonets (Y and Z Directions)
    The Y and Z bayonets worked very well. The water boat calibration worked well and the data collected was good.
    There are Standard labels created for the water boat calibration. After calibrating the bayonets please run the water boat using the STND Label provided. (See below Method for Label Generation for procedure in label generation if a new one is needed).
    Calipers (X Direction and Discrete measurements)
    The Calipers (X-axis and Discrete) had a couple issues.
    1. X-Axis: Velocities were too high (by about 80 – 100 m/s too high). Initially we thought it was a function of only the core liner thickness. Re-measuring the liner thickness gave a value of on average 2.7 mm. We changed the liner thickness from 3.2 to 2.7mm. On Exp. 320 the scientists varied the core liner thickness to correct for the high velocity measured by the transducers, however, varying the liner thickness did not bring the velocity into an acceptable range for us. Thus, another issue was contributing to the high velocities.
    2. X-Axis: (The following was addressed by Pawan Dewangan, PP Scientist, Exp 321).
    To address the above issue, Dewangan decided to evaluate/check the other parameters (system delay, caliper distance, pick travel time) used in the P-wave velocity calculation. He did this by measuring the velocity of water at room temperature with varying distances between the X-axis transducers.
    The velocity of the samples is calculated as follows,
    V=ΔX/ΔT,
    ΔX = XC- XL,
    ΔT = TP – TS – TL,
    Where XC is the caliper distance, XL is the liner thickness, TP is the picked traveltime, TS is the system delay (traveltime measured for zero sample thickness) and TL is the delay due to liner.
    The constants used were:
    XL = 2.7 mm, TS = 20.50 µs, TL = 1.26 µs assuming liner velocity of 2140 m/s.
    The following velocities were obtained,

    Sr. No

    26.88

    1699.2

    1497.7


    Clearly, the values that were being used were not correct (velocity should remain the same for the varying distances). Dewangan used the above data points to obtain better system delay time (Figure 1); the new values are as follows,
    XL = 2.7 mm, TS =19.811 µs, TL = 1.26 µs assuming liner velocity of 2140 m/s.

    Figure 1. Distance-traveltime plot of varying thickness of water column after correcting for liner. The derived velocity is close to 1495 m/s.
    Thus, the new System Delay accepted by scientists and used (for Site U1338) is TS =19.811 µs. This correction was not implemented for the first site (U1337), but the scientists will be correcting their data accordingly.
    3. Transducer lowering for discrete measurements would be better if the user could manually adjust the transducer height onto the sample (like the arrow used in the X-axis measurement). This would be helpful for samples that are too hard for the bayonets for too soft for the automatic lowering of the transducers. We had only one discrete measurement because of this issue. The sample was squashed by the transducers automatic closure. And thus no other discrete samples were measured.
    To Do: The above issue needs to be addressed - why would the system delay change? Or has the value always been incorrect.
    Labels have been created for the acrylic standards. Please, after calibrating and between measurements use these standards as QAQC. (See list and method below)

    DESCRIPTIVE AND INTERPRETIVE DATA CAPTURE (DescLOGIK)

    Zenon Mateo
    Summary
    Expedition 321 is the second part of the Pacific Equatorial Age Transect, continuing from Expedition 320 which drilled the northwestern sites. As a continuation of that expedition, most of the preparation for the core description process has already been done. Templates have been created and modified very slightly, selected values are in place, the previous group have noted and fixed some of the previous issues and a successful cross over with the previous group have all contributed to the overall success in the core description process of this expedition. However, there are still a few bugs and rooms for improvement that are listed in detail below. A very important lesson from Exp 321 is that the DESClogik system needs to be introduced to users as a data entry tool, ready for them to use once they get onboard, and the details about its features will be learned as they go along in using the software. For the micropaleontologists, they were given the full breadth of freedom in selecting their method of recording their data, ranging from the full use of DESClogik, to entering their data in Excel, thereby requiring the MLS to create the template and upload the data once they're done.
    As of Hole U1338B, 247 cores have been described for this expedition; another 20 cores was also processed from Hole U1336B

    Equipment Performance Summary

  1. Bugs
    1. In the graphical interface, the track data are not discriminated according to the instrument that captures them. Hence, data from both WRMST and Special Track or from different runs are combined, creating a saw-tooth plot. (Solution: plot only the latest data or provide a window for the user to select which one to plot)
    2. In the graphical interface, the "select interval" looses connection with the image track (i.e., it always draws the box in the XY track). (Solution: Restart DescLogik)
    3. Some images don't plot. (Solution: Restart graphical interface or DescLogik).
    4. Assignment of sublist to a bulk dynamic column creation: can it work if the list is by another author but is a global list?
    5. Units appear in some column headers but not in others.
    6. Cancel button in Change User window doesn't work
    7. Sometimes, track/logger data (already in database) do not display in the Graphical interface.
    8. After upload is completed, "Please wait for previous upload to finish" automatically appears (should be "Upload complete"?).
    9. Depths don't validate/upload when pasted into TDC, but only happens in certain machines (OK in my laptop, but not for the aft-port DESC machine). For CYL samples, if the top and bottom offsets are not entered, the top and bottom depths default to the top and bottom of the parent sample, which in this case would be the section.
    10. In bulk entry of the dynamic column manager, it errors out if no custom list is selected before creating the columns.
    11. (June 8, 2009; before starting radiolarian analysis for U1338B) A critical problem occurred when the 321_Radiolaria template was corrupted and unable to display the tabs for the spreadsheet. Workaround was to use Excel for the meantime until the problem is solved by the developers.
  2. Software enhancements
    1. Track data should only be from the latest run. In the distant future, provide option for user to select which version to display from which instrument.
    2. Create "Save As" function also for workspace. Consolidate Save, Save As and Open buttons and provide side window to select either template, or workspace.
    3. Improve on the template-workspace relationship, especially for micropaleo where a template will evolve as they find new species and add new columns, thereby breaking the link between template and workspace. This requires changing the template without affecting the workspace.
    4. Retain set track parameters (i.e., minimum and maximum values) for consistency when successively plotting data from different cores/samples.
    5. Alphabetize/sort workpspace list for easy.
    6. Tool to organize/manage workspace files per account.
    7. Prompt user to press "enter" once a template name has been selected. They always forget to do so!
    8. Don't make the downloaders too sensitive on font case (lower or upper) in order to limit choices (i..e., in filters)
    9. Save template settings (i.e., min, max)
    10. Symbols should not be automatically put in the track data; make it a user option.
  3. Suggestions to Users
    1. Re-start DescLogik for every core in order for the software to "refresh" itself.
    2. Create a workspace for each core.
    3. Always double check the workspace name that you "save as", otherwise you might be overwriting another workspace file.
  4. Notes
    1. Add Sample Master in the smear slides workflow.
  5. Tech Tid-Bits 
  6. One lesson from this expedition is the preparation of the templates before hand, at least for the core description part.  I'm basing this on the fact that for 321, we're in a way simply continuing the work of 320 and using their ready templates with minor modifications. It would be highly recommended that expedition managers send a spreadsheet and associated values per column to the core describers of an incoming expedition so that they can prepare, modify and adjust to the data entry form that they will be using.


  1. DESClogic has to be immediately introduced to the participants as a data entry tool.  I don't think they're too concerned about the details of how to create a template, what dynamic columns are and how data is parsed into the different components in the DB.  They can do and learn those along the way.


  1. It also helps to tutor them (i.e., be by their side) when they're working on their first few cores (about 10 for each shifts).  This includes the entire workflow for the describers, starting from the imaging logger.
  2. Hardware
    1. The entire core description table was moved 6 inches toward port in order to give ample space for the describers to maneuver in manning the tracks and in discussing features displayed in the monitors, which they've often done with the DESC graphical interface.



MICROSCOPY AND MICROPALEONTOLOGY LAB

Zenon Richard P. Mateo
Summary
Expedition 321 is the second part of the Pacific Equatorial Age Transect, continuing from Expedition 320 which drilled the northwestern sites. As a continuation of that expedition, several protocols and equipments have already been set up, with just a few minor modifications in the user-preferred microscope objectives and minor troubleshooting of phase condensers. A new SPOT CMOS camera is installed in Station S1 (SV-11). This camera is smaller than the previous SPOT CCD camera and is therefore suitable for the smaller stereoscopes in the laboratory. Most of the work done for both laboratories has been in providing needed chemical, labeling, storage and cleaning supplies (see details below). No major changes in laboratory layout or equipments.
For the entire expedition, there are 1,626 smear slides registered in the database; additional 73 smear slides are from Site U1336B. More smear slide samples were created for quick analysis but were not entered in the database.

Participants. During the expedition, both SV-11 stereoscopes were used for foraminiferal analysis; stations U2 for nannofossils, U3 for radiolarians, U5 for diatoms and U6 for sedimentology.

Instruments
A new CMOS SPOT camera (Idea 5MP) was added to the inventory for use in either of the SV-11 stereoscopes.
For Axioplan 90229

  1. Problem: Phase 2 did not have the characteristic high contrast image of speciments.

Solution: Align the phase rings of the condenser turret and the objective

    1. PH2 condenser should be engaged (facing front)
    2. Replace one of the eyepieces with the PhaCon or Auxiliary eyepiece. Focus the phase rings by slowly pulling the upper black rubber element.
    3. Insert two hex keys through the openings in the rear corner of the condenser holder.
    4. While looking through the PhaCon or Auxiliary eyepiece, rotate the keys until the dark and light rings are concentric or coincident.


  1. Problem: Phase 2 goes off center/alignment as the condenser turret is rotated (i.e., to PH3, H, D and back).

Solution: Tighten retaining ring for the PH2 phase stop.

    1. Make sure that PH2 is engaged (facing front).
    2. Remove the condenser turret by lowering the substage assembly and unscrewing the silver knob at the top.
    3. Once removed, flip the condenser.
    4. Tighten the retaining ring.


  1. Problem: Objectives get off centered easily, even for the Axioscopes. Solution: Make sure that the objective is not loose from its slot in the nosepiece.


Hardware
At the beginning of the expedition, participants were not able to properly adjust the tables. For some reason, a limit was previously put as to how far the tables could be raised. To reset the tables, simply press the down arrow for about 30 seconds until the legs bottom out. During the procedure, the legs should re-align themselves. Press the up button to desired height. Still, make sure that the power cables are unplugged so that users will not accidentally raise the tables and break any wall attachments or cabling.
A hose for compressed air was set-up by Gus in the Paleo Prep Lab for cleaning sieves. The small Fisher oven is not installed on the portside wall, between the two fume hoods, and is being used for drying foram samples.
Supplies

  1. The nannofossil paleontologists required additional cleaning of the "pre-cleaned" microscope slides, but the ship does not have the detergent that is acceptable to them.


  1. We ran out of pre-printed labeling stickers (white square sticker with Exp, site, hole, core); had to use the circular white or colored stickers.


  1. We also ran out of 8ml sample vials for storing processed samples. In the end, they settled with the 16ml vials although they are too big for their need.


  1. Pre-processing of samples for radiolarian analysis required the use of 30% HCl. Several small batches were made by Lisa Brandt because we only have old carboys that are not reliable for storing the solution.


Software
MIMC was only used for a few times during the start of the expedition. Several photomicrographs were collected by the paleontologists but they deemed that most of them are not of good quality for uploading into the database.
Calibration
Several objectives were switched or replaced to suit user's needs. However, the actual FOV were not yet measured. Suggest that this be done immediately if time permits.
Miscellaneous
A group discussion was also brought out near the beginning of the expedition about the possible use of HF in preparing samples for silicoflagellate analysis by Appy Sluijs. Other participants were mainly concerned about the potential risks, especially that several people are using the Paleo Prep Lab. The LO and Appy assured everyone about their expertise in handling such chemical and will only be used when no one else is in the lab. Though everyone settled on allowing such procedure to be performed, it was never done.

Paleomagnetics Lab

Margaret Hastedt
Scientists: James Channell and Toshi Yamazaki

Exp 321

Summary: This was a quiet leg overall, consisting almost entirely of simply running sections through the cryomag. The scientists ran their discrete samples in the cryo and measured bulk susceptibility with the new Kappabridge. Because it was an equatorial expedition, core orientation was a key part of magnetostratigraphic determinations. The new Flexit tools were used very heavily this leg.
Equipment Performance
The cryomag was run using the same version of the software in use on Exp. 320. I could not get Dwight's newer version debugged enough during the first logging period to deem it ready for the paleomagnetists. Other than the idiosyncrasies of the original version and the occasional doses of fluxjumping, the cryomag behaved well this cruise.
Quite a bit of time was spent cleaning up the database and eliminating duplicated, truncated or remeasured section data so that it wouldn't show up in the Tabular Web Reports. Because the uploaders were so slow, we tended to run them on several different workstations at the same time, piecemealing groups of runs to each. Inexperience, impatience and disorganization led to a lot of the 'bad' runs early in the cruise which then had to be cancelled in the LIMS. They will be permanently deleted later on the beach.
The Flexit tools behaved quite well overall with the occasional failures due to operator error or battery/power issues. Operator error consisted of me re-learning what Trevor had already figured out on 320. A bug in our modified Flexit software always leaves a temporary file intact which would normally be automatically deleted after a survey download. If you do not delete this file manually and proceed to run another survey, your next download will contain a copy of the last survey's data, not your new data. These files have a .SDF extension and reside in C:\documents and settings\all users\application data\Flexit\MeasureIT. It is easy to tell if you forgot to delete this file because the Flexit software will tell you that your tool still has data available for download after you launch MeasureIT. Exit the software, delete the .SDF file, and start again creating a new survey.
Flexit battery issues were two-fold: we ran out of commercially-produced battery packs mid-cruise and also were burned by battery failure in the wireless transceiver that is the interface between the tools and the computer. It is advisable to change out the 9V batteries in the wireless transceivers at the beginning of every cruise whether you think they need it or not. If it fails, your download will slow to a complete crawl. It will eventually finish hours later, and all you get is zeros for your data past the point where it failed.
The one survey failure we could not adequately explain happened at the beginning of the last survey for Hole 1338B using tool #936. There must have been some sort of glitch or power interruption inside the tool after the survey started. There were about 8 stations worth of anomalous data then the rest of the survey file was a copy of the old memory from the last survey. This is not the same as the bug-related duplicate data dumps mentioned above because the tool was recording something briefly, but then quit. We changed to new batteries and were careful to switch tools every 4-5 cores for the final hole of the site. The suspect battery was tested by the ET's but nothing was found. It had plenty of power left in it. It was the one and only time we had a failure like that.


Special Projects

  1. Began debugging Dwight's new version of the pass-through cryomag software
  • software Abort function fully enabled; allows the user to kill any step (measure or demag) at will and repeat it or stop completely. An excellent feature for remeasuring after a flux jump without having to start the measurement sequence from scratch. Ongoing project through the transit.
  • View Plots screen now plots all four data permutations on the same screens, allowing the scientist to very quickly assess the quality of the measurement.


  1. Jurie wired up the hardware Abort button to kill power to the motor instead of having a "soft kill" in the Galil controller. The downside of the latter is that the controller will immediately restart motion after a 'soft' abort if it receives another command to move from the software, which is common in the middle of a measurement sequence. Make sure you do not disable Off on Error in the Galil configuration! Otherwise the boat will take off like a shot when you release the hardware abort button, because the encoder is still on even if the motor isn't. It WILL try to catch up on its positioning and quite aggressively at that.


  1. A refill has been requested in Victoria since it is the last "cheap" portcall for getting liquid helium to the ship this year.


  1. We began an extensive review of the entire orientation process after problems were reported on Exp. 320 (see Methods section for details).


  • First of all Trevor, Mitch Malone and myself took all three tools to Ala Moana Beach park in Honolulu to get the tools well away from the ship for testing. We bought a camping compass to align the tool face (bottom notch) with magnetic north and did 5-minute surveys for each tool to assess their performance. All three tools indicated magnetic north properly (MTF angle in the processed files) within the error produced by hand-aligning and hand-holding the tools. Tool 938 indicated that it X-axis accelerometer had failed, but it still found magnetic north properly.
  • The second step of the review process included re-processing the raw .CSY files from Exp. 320 to look for possible problems. I used the Flexit software to process the raw files in order to get the magnetic toolface (MTF) results. I gave my picks to the paleomagnetists to see how they worked reorienting some of the 320 data. Initial results were promising so the scientists decided to continue deploying the tools on Exp. 321.
  • The third step recommended by the 320 paleomagnetists was to visit the Core Tech shop/rig floor and actually see how the tools are rigged up to the core barrel. This helped clear up any erroneous assumptions we might have made about how things are connected to each other. For details, please see the ODP Advanced Piston Corer documentation (2006) up in the Ops office.
  • The User Guide is being heavily revised with methods developed on this cruise for the new tools. The survey setup is quite a bit different than that for the old Tensor tools but overall data reduction is quite similar.


Type and number of measurements

    1. Sections measured in cryomag: 1365
    2. Number of runs (all demags): 3160
    3. Discrete samples measured in cryo: 375
    4. Cores oriented: 179

Exp 321T

Summary: The transit was spent mostly working on various loggers, mainly the SHMSL and NGR. Maintenance work and debugging was performed on the cryomag and its new software version.
Equipment Performance
Not much to report as the cryomag was not used by the visiting School of Rock. The helium boiloff rate since Singapore was calculated out and is just under 0.2 liters per day. We are trying to arrange a helium top-off for Victoria as of this writing, but it may be delayed until Yokohama.

Special Projects
The Haskris reservoir was drained and flushed with water plus a little bleach, then flushed again and refilled with DI water. The water used at Singapore had gotten black and gungy in the last 7 months. The drain hose was replaced with a fresh piece of Tygon tubing.
A very lengthy test was performed on Flexit tool #936. Jurie created a new battery pack for the tool and we began running 18-24 hour surveys plus data downloads to see how long the batteries would be usable. After two weeks and over 194,000 measurements the batteries are still going strong but seem to finally be approaching the end of their reliable voltages. We will continue the test until portcall.

DHML Temperature data:
Overview:
APCT3 Deployments were done on both sites U1337 and U1338
One SET deployment was done on site U1338
In total 15 APCT3 and 1 SET deployment were done during this expedition.
Barring one or two deployments, all yielded excellent returns with a high overall confidence in the measurements. The calm sea states encountered throughout the expedition was a contributor to the successful deployments, as was the procedure to have the passive compensator open during the measurement period. This restricted tool movement and very little friction induced temperature spikes were noted. Allegedly this procedure is not followed on the opposite crue. There is a good argument for making it (open compensator) a standard procedure.
TPFit software was used to estimate the undisturbed formation temperature from the tool decay data. APCT3 raw data files were uploaded to LIMS. At the time of writing this report the developers were working on ways to load the SET raw data and TPFit-data to LIMS. All data files are in a folder, 'Exp321 Temperature data' on the DHML PC and backed up on my laptop.
The SET tool deployment was the first for this tool on the JR.

3. Individual Instruments/Analysis
3.1. Alkalinity Titration
This was the last cruise we will use the current 702 SM Titrino system. A new instrument has been purchased and is being shipped to Victoria. 187 samples were analyzed for alkalinity. No major issues with the software. James Zhao the developer fixed the issue where the message pops up at the end of the titration saying "Saved into LIMS". This message was confusing, because the user still manually has to hit "Done/Save to LIMS" in order for the data point to be loaded. There might also be a couple other minor changes made to the program done on the transit.
3.2. CAHN Balance
CAHN balance model 30 with dual balance software was used to measure mass in the chemistry laboratory. Two major problems occurred during this expedition.
Software trouble – sometimes previous (old) mass was saved with current (new) container number when user click save button.
Hardware trouble – CAHN model 30 lost calibration at site U1337, and CAHN was calibrated once per day by chemists or technicians. After this problem occurred, less than 4 mg of mass couldn't measure by CAHN balance. CAHN balance model 30 was replaced with CAHN balance model 29 at site U1338. Unfortunately, CAHN model 29 also lost calibration at 09 June 09.
Special Note – other remaining software troubles
Stop function of balance software doesn't refresh screen, and an artistic wave or abnormal line are shown in the screen.
3.3. Cl Titration
The scientists performed all the chloride titrations this expedition. No problems were encountered with the hardware.
3.4. Coulometer (CaCO3 content)
632 samples were analyzed on the coulometer. Most of the issues encountered on the coulometer were caused by inaccuracies carried over from the CAHN balance. We did encounter several instances where the coulometer solution turned from its ordinary light blue color at 29% transmittance to a very dark royal blue color at 0% transmittance. We found that this was caused by analyzing samples that had a very high silica content, such as the diatom-rich samples. To avoid this, we asked the scientists to refrain from taking the CARB samples on the diatom layers.




3.5. Discrete Analysis (DA)
The DA did not work on this expedition. One of the consumables, the tubing kit, did not arrive at the Honolulu port call. This tubing is used in dispensing the aqueous material; since it was worn out, non-accurate amounts of liquids were dispensed. I tried to get the instrument working anyway, by increasing the tension on tubing. This allowed us to get somewhat accurate results on the nitrate/nitrite methods, but all other methods were unable to be calibrated. A new nitrate column was installed and appeared to be working, but eventually the results succumbed to the bad tubing. The tubing kit On Board amount has been increased, and replacements should be coming to Victoria.
3.6. Element Analyzer (TO and TOC analysis)
The Flash EA1112 Element Analyzer (CHNS analyzer) was used to measure total carbon content (TC) in bulk sediments and total organic carbon (TOC) content in sediments treated by acid. Total 274 samples were measured during this cruise. Instrument (FlashEA1112) performed without major trouble during this expedition. Because of gas leak between gas bottle storage and chemistry laboratory, He gas bottle was connected directly to the CHNS analyzer. Analytical method was as follows.
Furnace initial temperature – 900 degree C
Combustion temperature – 1800 degree C
Carrier gas flow – 140 ml/min
Oxygen flow – 250 ml/min
Oxygen flow timing – 5 sec
Oven temperature – 65 degree C
Run time – 600 sec
Since on-site inspection by Thermo's technician was suggested by previous onboard technician, special maintenance was conducted before 1st site. Bottom connection (18 mm diameter) was extremely dirty (Fig.3.6.1), and that washed by organic solvent (Methylene Chloride / Methanol mixture) using ultrasonic bath (30 min). Bottom O-ring of bottom connection was replaced because of degradation and consequent crack. Sample gas tube (PTFE tube) between bottom connection and water trap was replaced because of the existence of dirty particle materials. As one of cause of leak, remaining samples and/or contamination in an autosampler tray are suspected. Autosampler tray was opened, and wiped by alcohol. After treatment, leaks were checked under low temperature condition. After that, oven temperature was set for 400 degree C, and then leak was checked again.
NOTE – Bottom o-ring might replace every time when reactor is changed.
NOTE – leak must be checked under low temperature condition when reactor was replaced because you may have to decrease temperature again if you find leak. After oven temperature get high (400~600 degree C), you may have to check leak using Eager 300 operation software.

Figure 3.6.1. Bottom connection (before cleaning
Oven and Furnace were heated up 6 hour before measurement. Since sample gas tube was replaced, peak positions were adjusted using a chromatogram of approximately 0.4 mg sulfanilamide. Peak position was also adjusted when calibration standard was changed. Table 3.6.1. shows a retention time of a top of peak. Difference between retention times for two calibration standards was vanishingly small based on the range of detection time window, suggesting the length of sample tube and carrier gas flow is primary factor of retention time change.

Onboard minimum measurement, total carbon content, was performed upon Sulfanilamide standard (Costech, 031046) as calibration standard. Approximately 0.3 mg, 0.4~0.5 mg, and 0.6 ~ 0.7 mg Sulfanilamide were combusted with tin container without Vanadium Pentoxide (combustion improver). Linear fit was selected as calibration method and calibration factor was 0.999 or greater for Nitrogen and Carbon. When diatom ooze was loaded into a reactor, plenty of crystal water was released from siliceous sample. 2/3 of magnesium perchlorate change to sherbet, and escaped water from trap was detected by TCD as Hydrogen (Fig. 3.6.2). After the troubleshooting, 9 samples were measured successfully, but the reactor died soon. Because trapped water in the sample tube and/or reactor blocked carrier gas flow, sample gas tube between reactor and water trap was replaced. Also water trap was replaced.

Figure 3.6.2. Chromatogram of siliceous sample. Third peak is hydrogen.
New calibration procedure, "Cysteine Method" introduced by Exp.320 chemists was carried out during Exp.321. Based on the method introduced in the Chemistry Laboratory technician Report for Expedition 321, aliquot 10 ¿l, 20 ¿l, 30 ¿l, and 40 ¿l of 80 mmol Cysteine stock solution were placed in a silver container (10x10 mm), and then solutions were dried under 50 degree C using a low-temperature oven. Linear fit was selected as calibration method and calibration factor was 0.999 or greater for Nitrogen and Carbon. Peak area and height of upper three samples obtained from Site U1336 Hole B were lower than those of 10 ¿l Cysteine (Fig. 3.6.3), suggesting calibration range was not low enough. Dr. Shinya Yamamoto modified method, and 5 ¿l Cysteine and 8 ¿l Cysteine were associated with calibration to measure TOC and TC, which have under 1 w% of carbon content.

.
Approximately 30 mg of aliquot freeze dried samples were placed into a pre-baked (450 degree C, 3 hours) silver container, and were acidified by 2 mol HCl to remove CaCO3. Carbonate free sediments were dried completely over the 50 degree C heater overnight. Well dried sample and silver cup were wrapped by tin disc, and then combusted under oxygen flow in the reactor set in the CHNS analyzer. Since silver container is approximately 3 times bigger than tin container, ash holder was replaced in respect to each 50 measurement. To gain maintenance time, ash holders of used reactors were collected, cleaned, and pre-baled under 450 degree C (3 hours).
Calibration and CV data were saved into the local PC because new standards were not registered into the LIMS because of technical problem.
Calculated TOC (TOC_cal), Total Carbon (measured by CHNS analyzer) – Inorganic Carbon (measured by coulometer), were fluctuated between -6.27 and 5.82. Although trend is inexplicit, TOC_cal tend to be decrease with increasing calcium carbonate content (Fig. 3.6.4). TOC_cal also tends to be scatter when total organic carbon (TOC) content of samples were low (< 0.3 w%). Probably weighing error and inadequate homogenization of samples could be primary reason of scattering result. 0.3 w% might be limitation of this analysis in the offshore laboratory.

Figure 3.6.5. Relationship between calculated TOC and total organic carbon content measured by CHNS using samples treated by acid. Pink color means minus value.
3.7. Gas Chromatograph (GC, Gas Safety Monitoring)
HP6890 Gas chromatography equipped with FID (GC3) was used to measure head space gas samples obtained from the middle of cores. 36 samples for site U1337 and 39 samples for site U1338 were measured, and only methane was detected. Gas concentrations at two sites fluctuated between 0 ppm and 1.330 ppm at site U1337 and 0 ppm and 1.663 ppm at site U1338 (Fig. 3.7.1), respectively.
GC3 was calibrated using only four standard gases, A, B, C, and D, because expected gas concentration around this area was extremely low (Fig. 3.7.2). Integration setting was not enough to integrate whole range of calibration standard. It might be a good idea to check chromatogram (integration) before upload data into the database. Because of above reason, automatic upload was cut off during this cruise.
HP6890 GC with TCD and FID (GC-NGA) was also calibrated using same standard gases. Since natural gas concentration detected at site U1337 was extremely low, NGA was turned off after the drilling at site U1337 to save carrier (He) gas.
Special Note – remaining software troubles
NGA data has not been loaded into the LIMS. Based on the several test, NGA data was uploaded using GC3 loader, suggesting NGA loader has problem.

Figure 3.7.1. Methane concentration at sites U1337 and U1338.

Figure 3.7.2. Calibration curve for Methane.
3.8. ICP
The ICP was used for both IW/RHIZON water analysis (majors + minor trace elements) and for sediment bulk analysis. The sample total was 202 water samples and 110 bulk sediment samples.
During the initial transit to the first site, it was discovered that the exhaust line to the ICP had been turned off during port call. This allowed ~ 1 quart of condensation/rain to get into the instrument. All of the covers were removed, and fans were placed on the instrument to fully dry it out. The instrument started up successfully after this.
After the initial start up, it was observed that a lot of burn damage was happening to the torches. White spots grew on the torch, and over time led to total erosion of the torch tip. We discovered that the exhaust flow was too high. It was causing the flame to bend upward, thus damaging the torch. We removed the exhaust tube from the main line and rerouted it into the heat hood. After doing this, torch life has been greatly increased. Before, a torch was trashed after one sediment run. We've been using the same torch on 3+ sediment runs with no extensive damage to the torch.
We have noticed that there does still seem to be a slight amount of erosion/damage happening to one small area of the torch. Upon discussion with the company, we think this might be due to a buildup of material on the air knife, which would then lead to disturbances in the plasma flow on that corner of the torch. It is recommended that we clean the air knife. I will do this and update it in the post San Diego section of the tech report.
3.9. Ion Chromatograph (IC)
The IC ran well this cruise. No new sample vial/septa sets arrived in Honolulu, so the old vials were re-used. A complete check of all parts on ASMAN inventory was done at the beginning of the expedition.
Before analyzing samples from the first site, the anion suppressor started leaking from the bottom seam. The repair procedure described in the instrument manual was attempted, but was not successful. The suppressor was replaced with one of the spares and then worked fine.
A total of 201 samples were analyzed for cations and anions. There were no major issues with this instrument. The uploader also worked without incident.
One small workflow issue is that dilutions take much longer using the IC autosampler than they would if we were using the Hamilton Auto-diluter. I think on fast MBIO cruises it would be much more efficient to quickly dilute the sample using the Hamilton, then run it on the IC. This would bring the analysis time for sulfate down to 15 minutes, versus the current 30 minutes.
Parts were ordered for the Hamilton diluter and should hopefully arrive in Victoria.
3.10. Carver Press
Three mechanical operation carver press and one manual operation carver press were used during the expedition. Square shape pedestals were installed (Fig 3.10.1). New idea, PTFE tape sealing for red-rubber disc (Fig 3.10.2), was tested. New technique was of assistance to water leak.
Two presses were stopped due to mechanical trouble at site U1337, and were maintained by ETs. Troubleshooting will continue during transit from San Diego to Victoria.

Figure 3.10.1 Pedestal.

Figure 3.10.2 Rubber disc with PTFE seal.

4. Laboratory Safety
Chemistry technicians climb on the gas bottles to check pressure, switch valve, and change bottles during this cruise. Gas bottle holders were not stable. Distance between gas bottles and shelf was not enough as work space. Gas bottles are placed at isolated area, and usually chemistry technician works solo. Therefore, there are several potential safety problems at gas bottle storage area.
During this cruise, as interim solution, small ladder was put under the regulator by chemistry technician. This idea would be one of mid- to long-term solution. If so, however, chemistry technician will have to rearrange bottles to avoid a dangerous situation, such as climbing gas bottles. Rearrangement of gas bottles requires two or three personnel. Buddy system would be nice to prevent hazard and/or to take immediate action on the injury issue. However, a lot of IODP personnel don't know the location of gas bottles and potential hazard in the gas bottle storage.
As future recommendation, it would be nice somebody who charged on the onboard safety issue refer the above potential hazard, location, and the importance of buddy system in the laboratory safety training on the JR.

XRAY/ICP PREP LAB

Robert E. Olivas

Exp 321

Summary:
The lab processed 13 XRD samples, 141 ICP samples and standards and 35 Carbonate Leaching samples during Expedition 321. The Bruker D4 diffractometer worked well but experienced a few problems with the cooling water system. The Cahn 29 electrobalance experienced problems resulting in procedural and software changes but without a loss of data.
Equipment Performance Summary:
The Bead Sampler NT-2100 performed well after replacing one of the exhaust fan's noisy bearing; it is recommended that the second bearing be replaced. The temperature and time settings used were the same as on E-320 and worked well except for the FUSE-1 temperature setting would create an over current warning. By lowering the current setting on FUSE-1 the over current warning light would go out, then after starting the machine you can raise the current to the desired temperature. There is an unusual intermittent noise created when the machine is in the AGIT cycle and rotating clockwise. It is believed to be caused by a "chattering relay" that does not effect its operation. The platinum crucibles are not in good shape making it difficult to release the beads without damaging the crucibles further. Crucibles with severe "cupping" on the bottom were pounded flat using a delron drift. In addition, procedures for removing the crucible from the furnace were modified making it much easier to remove the bead. As soon as the bead sampler stops its AGIT cycle open the hood quickly, pick up the crucible and hold it over the coils while rotating the molten bead so that all splatters and secondary beads become one large bead. Tilt the crucible 45 degrees while the bead solidifies against the wall of the crucible. When the buzzer sounds place the crucible on the cooling fan. This technique often results in the bead separating itself from the crucible with out pounding on it. Please use extreme caution, wear protective clothing plus safety goggles (or shield) while using this procedure; handling molten glass on a rolling ship is dangerous.
The Bruker D4 Endeavor diffractometer experienced two problems creating alarms. Both problems concerned cooling water but were unrelated one another. The first problem created an over temperature condition caused by either a clogged filter in the Haskris cooling unit or an accidental change in the temperature settings on the Haskris. Spare filters have been ordered. Filters should be changed and cleaned on a routine basis at least once every two months. Bruker recommends one of the following methods to clean the water:
METHOD 1:
Add one cup of chlorine bleach per 15 gallons of water. Circulate 20-30 minutes. Drain the system, flush the system, and refill with clean, distilled water.
METHOD 2:
Add one pint of hydrogen peroxide per 15 gallons of water. Circulate 20-30 minutes. Drain the system, flush the system, and refill with clean, distilled water.
The temperature controls on the Haskris are located behind the chair for the weighing station and can easily be accidently changed. The second problem was created when a quick disconnect fitting connecting water to the X-ray tube started leaking and flooded the base of the unit and spilling on to the floor. The leak luckily was not catastrophic so there was no damage to electronics or other components in the machine. Bruker recommended using a standard hose clamp on the fitting or bypassing the fitting. We installed a hose clamp and the leak was repaired. Note that the fitting did not have any hose clamps on it.
Cahn 29 Automatic Electrobalance experienced a number of problems that the programmers were working on for the first half of the voyage. In addition it appears the calibration was lost when someone hit the CAL button. Recommend disabling this button in the future so that it can only be used while the ship is in port. The Chem. lab's Cahn experienced similar problems so it's possible the Chemists (scientists) may have been using the CAL when they should not have, they used the X-ray lab's balance regularly. Because of the suspected calibration problem weighing procedures were modified whereas we tarred the balance with the desired final weight on both pans, then after removing the calibration weight from the unknown pan we added sample until the balance read zero, i.e. the desired weight or within an acceptable error range. ICP results from beads made using this technique were very good.
Loss on Ignition (LOI) was determined on hard rock standards using the Mettler Toledo balance system without problems; LOI was not measured on sediments. It was necessary to use the fused quartz crucibles that weight between 16 and 20g. The Mettler balances are able to handle this weight without problems. The larger crucibles were used as holders during fusion in the furnace.
The Fisher furnace used for LOI is used regularly by the Chemists and Microbiologists, thereby making it necessary to ensure the desired LOI fusion program is entered into the machine before use.
The new freeze dryer was tested satisfactorily but used very little on this expedition. All ICP samples were taken from the CARB samples that were dried and powdered in the Chem. Lab. The small bell jar ordered with the freeze dryer was used with the Chem. Lab's freeze dryer.
The Haskris water chiller worked fine with the exception noted above in the Bruker section.. There is a minor issue with the ship's chill water lines going to the Haskris in that water condensates on them creating a pool of water on the floor. Suggest insulating these lines to prevent this problem. The tank and water were cleaned using METHOD 1 above but instead of flushing the lines, the water was changed in the reservoir two times after the bleach was removed.
Special Projects:
Modified the core splitting bench by elevating the port side thereby allowing water to drain toward the starboard side where the drain is located. Did not have enough material (lag screws) to finish attaching the port side support to the table; it is held in place with only three screws.
Reorganized the x-ray sample preparation area in the Thin Section Lab. The oven and XPRESS machine were mounted to a shelf on the starboard side of the lab thereby creating additional room near the sink to clean crucibles. Material to fill in the gap between the sink and the lab bench just forward of the sink has been ordered. A temporary support for the shelf holding the container for NannoPure water was constructed so it will hold the water container. The support works fine but a more permanent support or shelf should be fabricated.
Removed 72 bottles of pre-weighed flux from the inventory. The flux appears old and clumped together as if moisture got inside which makes it impossible to mix with sample before making a bead. In addition, the caps for these bottles were sealed with what appears to be an inexpensive electricians tape. When removing the tape a residue is left which has to be cleaned off with isopropyl alcohol before use. These vials are boxed and marked, "FLUX IS OLD USE ONLY IF THERE IS NO MORE". Believe all new bottles of pre-weighed flux will have their caps sealed with parafilm.
Type and Number of Measurements:
13 XRD sediment samples were analyzed. One sample was taken with a toothpick and had to be put into solution and placed on the quartz insert with an eyedropper. The sample was then dried and processed normally. One sample was washed and centrifuged four times to remove salt water before analysis. The remainder of the samples were processed as normal pressed powders using the scan parameters set up on E-320.
141 beads were prepared for ICP analysis using the Cahn balance and the NT-2100 Bead Sampler in full auto mode.
35 samples were weighed out using the Cahn balance in support of a special experiment to leach carbonates from samples.
Miscellaneous Issues:
Someone needs to sail on each voyage that is experienced in analyzing XRD results using the software supported by IODP, i.e. EVA. Scientists on this voyage wanted to use MacDiff but for some reason it is not available. They used the EVA software with some success but requiring them to use one computer in the IT user area is onerous and a problem for most scientists. They advise the software is not user friendly and is difficult to work with. It has not been the techs responsibility to evaluate the data and advice scientists what the results are although I felt that is what they expected.
The computer in the lab is very slow and crashed three times during this cruise. Chemists are using the balance controlled by the lab's computer a lot. Weighing and running the diffractometer should not be done at the same time. A second computer for this lab should be a requirement if chemists will be using the balance.
Expect there will be ICP contamination problems on hard rock legs when ICP sample preparation and thin sections are being made in the same small space. Making thin sections is a relatively dirty process with sample, diamond, iron and abrasive dust particles floating around in the lab. If there are no Microbiologists aboard the Shatter Box should be moved to the Chem/Microbiology Lab.

Exp 321T

Summary:
No samples were processed in the lab. Programmers worked on the Mettler and Cahn balance programs. Lab user manuals were reviewed for accuracy and recommended changes.
Equipment Performance Summary:
Laboratory equipment other than the Haskris water chiller and Cahn Balance were not operated during the transit.
The Haskris water chiller worked fine and experienced no problems. It is recommended that whenever water is added to the reservoir that it be "fresh". Given that we can not use additives of any kind in the water to hold down growth of organisms we should not be storing water in containers that are exposed to light. If the reservoir needs water use only water from the Chem or Thin section labs purification units and do not store it. The problem with water condensing on the chill water hoses could not be addressed because there is no insulation aboard. A small tray under the hoses works well to collect the water but needs to be emptied weekly.
The Cahn balance and programs were modified by David Fackler. After calibrating the balance in San Diego he made extensive measurements and created a log that will record all measurements. See Fackler's report.
Special Projects:
Haskris. - Made a Plexiglas shield to protect and prevent the Haskris controls from being accidently changed or damaged when the chair at the balance station bumps into the controller.
Core Reefer - Removed the forward/starboard and aft/port refrigeration units thereby creating additional space to store cores. These refrigeration units and fans are stored in the heavy tools storage area.
Additional shelves and core racks were constructed in the reefer. One row with three bins was constructed in the center of the reefer. Bin spacing is essentially the same as those already in the reefer and should allow the electric fork lift to move pallets of core from the floor to the shelf. Recommend that additional boxes be added to the pallet and strapped down before moving to the shelf. Some of the bins are narrower or located near the columns in the reefer so the electric fork lift can not be used to move the pallet out of the bin or up to the shelf; recommend using one of the narrow manual forklifts to remove the pallet, add core, strap and then use the electric forklift to lift it on to the shelf. If all shelves and bins are full then core can be dense packed in the aisles so that about 4,500 meters of core can be stored in this area.
The battery storage cabinet was moved forward on the starboard side and additional shelves added to this area.
Unistrut – Used some of the Unistrut materials stored on top of the lab stack to complete the racks and shelves in the reefer. All of the Unistrut hardware and 8 foot powder coated U channels are now stored in pallet stores and hardware stores.
Type and Number of Measurements:
No measurements were taken on the transit other than those taken by the programmers with the Cahn balance and Mettler balances, see David Fackler's report.
Miscellaneous Issues:
The core reefer is too small to hold cores from high recovery expeditions. Recommend using portable reefer containers for high recovery legs and if you are not able to ship cores after each voyage. In addition, it would be advisable to develop a method of stacking pallets (core boxes) in shipping containers so that cores on the bottom row are not crushed and you can utilize the maximum weight capacity of the reefer container. Most containers can hold over 40,000 pounds of cargo and presently we are only shipping about 28,000 pounds in a container. The Program is paying the same amount to ship 28,000 pounds as it would to ship 34,000 pounds per 85% utilization rule for exclusive container use.

Summary:
Overall, the information systems aboard provided an efficient method in which to store data from the expedition. Most of information technology related hardware performed well. The software networking, applications and servers had some issues that were corrected or are being corrected.
Equipment Performance Summary
Hardware
The hardware performed well. Issues concerning hardware include air conditioning, power and data center design, all of which performed satisfactorily. Fifteen VBrick decoders have failed and will be shipped to the vendor. Meanwhile, the vendor is preparing fifteen VBrick decoders to be delivered to College Station, which will in turn be shipped to Victoria to meet us there. In several instances memory was added to allow the software to run with more capability.
Software
Many different issues surrounded software and networking. Many instances involved user training. Other instances required reconfiguration. New software was installed where required. Other software and operating systems were updated.
Information Systems
Details concerning hardware and software follow below:

  4. We started the upgrade to leopard on the Macs, and stopped because of a problem installing printers under iPrint on the new operating system. We have since found a solution, but have not finished the upgrade, also with the upgrade some software has to be "repaired" because of the operating system change.
  5. We have created a share that the Mcafee virus software can update from, so that we can limit the satellite time to only one computer.
  6. Video Conferencing with Leslie at Ocean Leadership went very well after some system configuration.
  7. There were some problems with Vbrick set top boxes. We are working with the manufacturer to have VBricks crossed shipped so that we will have replacements waiting for us in Victoria.
  8. We worked on creating an Electronic Wiring map of all the network drops on the ship. We should be able to complete it in port call.

Electronic Techincians Report

J Kotze, E Claassen

Exp 321

Core Lab

  1. 1.Replaced UV light fitting, test serviceable .Replaced broken ceiling boards . Fitted power supplies into new enclosures for core lab equipment. Installed a audio amplifier, build shelf and change speaker cables to new amplifier. Build cutter for "Glad wrap" on description table.
  2. Reduced helium line pressure to Pygnometer from 26lb to 20lb and recalibrated. IT's did the necessary ramp up calibrations to the software as well. The transducers that were initially installed are 20lb/5V units. 5 cells within normal specs. No 4 cell has a leaky inlet valve. No visible damage or abnormalities but still leaking slowly. Ordered a new solenoid valve and 4 more for spares to keep in stock. Cell 6 developed a slight volume calibration error during the cruise ,We need to spend some time with Erik on this cell. I have already done a analogue, "logged test run" on it and the solenoids seems in perfect working order, this is the reason I will need Erik to do the software side with me so we can determine where the error originates from. This should not be a major issue and we plan to do it on the transit to Victoria.
  3. A set of lapidary blades were ordered for the circular core splitter. We found that the slotted high speed blades working very well on all harder cores does not do well where the intermediate cores between the APC and XCB are splitted as most of these cores consists of a biscuit like structure, that is where you get harder biscuits packed in soft sediment, the slotted blades feeds too much water through the cutting face washing out the soft sediment and cause the biscuits to get loose inside the core liner ,this in turn causes a high pitched vibration on the plastic liner and causes the biscuits to roll around and one ends up with different facets being cut on the core surface. This does not work well with the digital imaging camera as the core surface reflects the light at different angles. The new smooth lapidary blades without slots will improve the cutting "whine" on the liner and reduce the water wash through the liner. This should improve the situation a lot. This blades should work with any other hard cores as well. The slotted blades can be used in future when drilling hard rock, so it will still be of good value there. The water jet solenoid were rewired to open before the cutting motor actually starts, it comes on when the 3 phase switch to the motor is turned on, this helps to clear the mud after the cutting is done and washes the mud off once the blade is through at the end making it visible and helps reduce the winding down noise from the blade as it breaks the blade resonance. A heavier water shield at the back of the blade and cover for servo motor where made to minimize water spray during cutting operation. The super saw with the new electronic joystick control looks like a winner to me and I think that the techs will agree!

It might be a good idea to sent this report to Bill M. for notification.

  1. Changed emergency stop switch on P-mag, the switch was wired as a software command to the PC to stop but it was changed as a power cut-off switch to the drive motor. The command to the PC was not a viable option as the stop command gets entered into a command queue to the PC and does not always react fast enough.
  2. Repair broken sensor cable on the digital imaging camera system after a run failure.
  3. Extensive analyzing were done on the new Flexit tool batteries to determine the characteristics of the CR123A batteries under different working conditions . This batteries together with the new technology electronics are very power efficient and can log for literally hundreds of hrs. We gave it a series of test runs under different conditions with new and used cells and we built a test circuit and analyzer that run endurance tests and logging it the same time, this is given in soft and paper copy printed graph of the batteries' condition to minimize the risk of installing batteries that will not make the total logging period that can last for many hours if it was used during a previous cruise. We are currently undertaking a 24/7 test run on the Flexit tool started at the end of the last hole and can take as far as the end of expedition ending in Victoria (plus minus 3 weeks) if the batteries can push it till there.
  4. All hard copy test results will be kept by Maggie H. for future reference in the normal filing system as used by her.


Paleo lab
Replaced cable on Barnstead water purifier with made up cable to standby power outlet .Install sensor on hoods with silicon tubing, Install stops for sash hoods .
Install latch and lock on cupboard for HF chemicals.
ET Shop
Component racks ( 12 new 5 used) were installed and components where sorted and put into racks, this will be a ongoing job for quite a while although it is almost filled up with many spare parts still to be packed out. It is a tedious job as many of the semiconductors are very old and not used in any electronic equipment any more, It just takes up valuable space. The sorting of semiconductors takes a lot of time as many of them are not known any more and has to be looked up on the internet pulling the PDF files to determine their original specifications, the newer instruments use a lot of new technology which is much smaller and mostly use surface mount components,( this be the reason for the ordering of a tweezers style multi meter as a complimentary tool with the other new Fluke) some of the older components are still useful as it can be used in building ad-hoc test circuits, with the bigger "old style" components makes life easier for bench test circuitry although not of much use in most new instruments as replacements because of its physical dimensions. Some of it are still used as is in power supplies and other heavier power circuits . Most of our old TTL logic ic's as were used in the old instruments as the rock eval and old XRD etc. is of no use any more, still can't get it over our hearts to discard it, we will store them in boxes till such time we are confident that the time has come to do so.
Stacks of battery related issues where solved during the trip. This varied between just pure Timex batteries to batteries that could be rejuvenated as more and more equipment relies on battery power with sophisticated charging systems and higher capacitance lightweight cells, Gone are the days of just nickel/cadmium cells alone, it varies from Ni/cad, Ni /Me ,Lithium ion and Lipo/polimer and more. Some of which can have serious implications if not handled and monitored correctly and need a management system and procedure to keep it safe and functioning well.

Microscope lab
No Problems here
Down hole lab
Prepare APC 3 temperature tools, check program and operations with Mike Meiring. Ran down hole tools APC-T 3 tool on site U 1337 on hole A and B run set tool on site U1337 hole C. Run down hole tools APC-3 on site 1338 hole A and C. We performed the down hole tool runs when Mike M. was not available between 6-6 nights.
Mike will do a complete report on the DHML as he requested.
The new down hole Set/APCT3/Flexit tools are impressive, very reliable, user friendly and exceptionally accurate , what a pleasure !
Chem Lab
Install sensors on hoods with silicon tubing. Install stops for sash hoods.
Repair carver press , old press burned both relays, removed and repaired, reinstalled working, One new press burned a relay and timer as well , removed and repaired, reinstalled .
Repaired pressure gauge on carver press. Fixed a oil leak on the old carver press as well.
Repaired plastic heat sealer, element and wiring fixed . Repair Cahn Balance model C- 29 cable connection from main PC board to computer.
Replaced all Tantalum condensers on Cahn balance model C-31,both on Power supply and interconnection boards, This type capacitors have a tendency to get old and change capacity causing this type of erratic errors and has to be rebooted to get up and going again. Stable after replacements
X-ray lab
Replaced bearings on bead maker extractor fan, extra bearings are ordered.
Bob asked to have a look at the Cahn balance as it had a calibration irregularity on the 100Mg calibration but nothing substantial could be found, this only occurred when this weights were used with the particular paper former which serves as a vial, Bob did some more tests with the IT guys and it seems to be okay again. A bit of static were present and we tried grounding everything and the static vanished. No complaints again.
Thin section lab
Repair water purifier, Barnstead reverse osmosis, replaced power supply and controller card, tested working, make up longer power cable to standby power outlet, repaired internal wiring and plugs.
Sub Sea
We did not do anything here, Mike M. was busy working on the MRU and " Rigwatch" most of the time but we were not involved.

Underway lab
Assisted with making up the VSP guns , cables and testing of air supply, bleed system, and build up pressure for guns before use, the two "double gun" arrangement works excellent. Great job and engineering Gus !! with Etienne assisting him and operating the electronics and hardware they made a commendable example of professionalism !
Curator office
Build shelf for amplifier, installed two speakers. Yamaha amplifier and all cabling.
Entertainment
Gym
Installed new sound system in gym, new amplifier and four new speakers with cabling.
Repaired door on locker, riveted door back on locker.
Movie room
Neaten up all cabling and speakers wires for entertainment centre. Install two new speakers on entertainment centre, system 7.1 surround system
Conference room
Replaced broken ceiling boards and made up cables and installed it for cameras for conference calls
Pallet store & Storage bay
1.Installed freezer extension cable. Changed backup 3.6V battery pack for freezer controller.
2.Replaced motor on drill press & rewire.
3. Install speaker in store
4.Forma Freezer (-80 degree) failed due to apparent low gas initially, after a vacuum and refill by the ODL engineers it started tripping on head pressure, this might indicate a blockage in the evaporator orifice or a possible transport problem to the ship. Oil with a bit of sump grid might have caused oil to run into gas pipes. This is just a guess as it can be one or two other problems as well but that will only be possible to see once the unit has been opened and checked. a Replacement or port service call will have to be arranged.
After reading email conversation from Brad and Roy and Phil R. it seems that the gas pressure was getting lower during previous expedition and that the reading that it gave was -36 degrees, I think that was a true reading and not a display problem. (Physically there will be not much difference in looking into a Freezer at -36 and -80 Degrees. The temperature showed +17 degrees at the beginning of this cruise and there was no sign of any cooling, the water was actually hanging in drops on the inside. This was the point that Ian Barnes (ODL engineer) offered help as he has the tools for refilling the Freezer, after this it started tripping on head pressure seconds after startup. I'm not sure what the most cost effective way will be to deal with here as it seems that the freezer is old and just might keep on pushing costs. I have a notion that the evaporator orifice are blocked inside the expansion tube at the moment. The mains supply to the unit is sufficient and that is not the problem. It might be a good idea to get a service technician in port for evaluation.
Store rooms and wood workshop
Installed speakers and amp in both store rooms, landing area and workshop. Did some repairs on spare carver press kept in store as spare, it had bad relays itself.
General
All systems and instruments worked satisfactorily with the normal attention that it needs from time to time but a great cruise with minimum of hassles, Most detailed work done was general refinement and not modifications as such, the only modification was the safety circuit on the P-mag as mentioned earlier in the report. General cleaning up of equipment and workspace ongoing ,especially the ET-shop which normally functions throughout till the end of expedition when it will be handed over in a clean/safe working area.

Exp 321T

Labs
1. Enclosures for core lab power supplies were build with ventilation holes and extraction fans and locks. 8 supplies are in 7 enclosures.
2. All power extention cords were removed as needed and power cords lengthened to reach receptacles.
3. The island table in down hole lab, was sanded down and covered with bar top resin to protect table from damage due to the heavy nature of tool's that are used in the lab. Final finishing work to the edges are still to be done and will be before getting to Victoria and corner pipe vice will be installed back.
4. NGR noise were reduced by building shields around Multi System Track stepper motor and amp, this is only a temporary solution to the interference, a more permanent solution will be performed in Yokohama when materials are received from College station.
5. Pycnometer cell 5 and 6 were worked on PC boards were removed from bottom to top to be more easily worked on, Cell no's 4,5& 6 electronic boards were moved to the top, this makes diagnostics much less time consuming as measurements can be done without having to remove cells physically before reaching the controller boards. 3 mosfet IC's on controller board's were replaced which where faulty. All of them had one channel drawing too much current pulling down the 12v supply that supplies the solenoid valves making it difficult for them to open and close properly .Cell 4 still needs a new solenoid , and spares are on order for cell it. The pygnometer was calibrated for the next expedition.
Cells 1,2& 3 are still in same operating condition and their boards will be moved over with our next expedition as time is running out and this is a tedious time consuming project. Fly leads were brought out from pressure transducers to measure directly onto them if readings on the PC seems questionable, this makes diagnostics much easier. The pygnometer are still in process of refinement and without a doubt it will be a big improvement on the old one eventually, it takes a bit of time to work through all the steps to get to the target and keep it in operational condition throughout the expedition. This refinements can only happen when its not in use and a bit of time can be allowed for a next bit of work. Mike Meiring will bring some spare IC's that I asked him to bring with as it might be needed during the next expedition and it's a bit late for the normal ordering channels. He sent a reply to confirm that it will be there in Victoria.
A new calibration test unit is currently under construction to use in aid of calibrating the Pygnometer in future, this will simulate the standard outputs from the transducers and will help getting a more accurate calibration as it makes the need for a stable gas line and healthy transducers unnecessary and will give a very stable output voltage that will factor out all "unknowns"
6. P-mag Haskris water pump was removed and replaced with a spare from the X-ray lab, impeller blades were broken .. System was flushed and cleaned out. Spares were ordered to replenish.
7. The Flexit Battery diagnostic endurance test is still ongoing since the 16th of June, it is still running but the batteries are getting weaker now and it is expected that they just might make it up to Victoria, that will give us a valuable indication of what to expect to get out of the lifespan of the battery set in future.

All projects on our list of things to do were completed, extra repairs were also performed and completed, for next expedition, finalizing of one or two details will complete everything.

Engineering Report


Mike Meiring







Overview:
The challenge on Exp 321 was to get the RIS system serviceable, following the flooding of the Master and Standby PC's in sub-sea and the failure of the Crio Data-box controller during Exp 320. Following the installation in Singapore, some had yet to be expended to customize the system to comply to JR specific needs.A number of sensors were still not working and processes in the system needed streamlining.
Downhole temperature measurements were done from the DHML. Sixteen deployments were made, all returning high confidence data.
Orientation with the Flexit tools was coordinated by Margaret Hastedt from the Paleomagnetics lab and provided generally reliable results.

A) DHML Temperature tools.
See DHML report.

B) DHML Orientation tools
See Paleomagnetics lab report.

C) VIT equipment status.
The VIT system remains reliable, simple and repairable. It is well maintained and sufficient spares remain on board to provide continuing service to the end of the current program (2013)
There are three serviceable cameras with two high pressure housings.
Four lighting lenses are available (two spare). Lenses are a low maintenance item and similar devices are available as 'off the shelf' items.
Two complete telemetry pods and three serviceable sonar heads are on board.
<span style="color: #231f20">The winch had been refurbished during SODV and two new spare coaxial cables were purchased.</span>
<span style="color: #231f20">Suggestions for equipment renewal:</span>
The technology used on the current VIT system is obsolete and support from manufacturers is questionable. For this reason consideration must be given to equipment renewal by 2013.
<span style="color: #231f20">The electronic system should be renewed as a whole.</span>
<span style="color: #231f20">The telemetry system provides a link between the sub and above sea devices and is designed as an integrated system with the devices it supports. It converts and combines all device data to a format that allows it to be transmitted up the coaxial cable to the surface for reconstruction and display. For this reason it is not advisable to incrementally renew individual devices. This could require extensive modifications to either the telemetry system or the device.</span>

D) RIG INSTRUMENTATION:
Canrig representative, Charles La Bounty was sent to Honolulu port call. He replaced the Master PC and the faulty Crio controller. He loaded a mirror image of the master PC to the RIS Standby. The Standby PC and monitor were handed over to IODP IT. The replaced Master was handed to ODL ETs
The system functioned normally.
Relocating Master PC.
From what happened on Exp 320, it was clear that the Master PC had to be moved to a more environmentally friendly location. The Master PC was re-located to the Computer server room. It is accessed from the Engineering workstation in the Ops. Office via RADMIN, a remote access software package. The Master serial ports were extended remotely with two Startech NETRS232 Ethernet /Serial port converters. One each for Tracer-Pump (Sub-sea shop) and the Video overlay data (Coredeck network locker).
Pipe-counter:
I constructed an optical switch mounting, to provide additional horizontal separation. The switches were wired to the Data box and the variable configured. The counter performed well but could not be set to a specific value. Correspondence with Epoch support confirmed that it was not possible to set counter to a specific value (see e-mail in correspondence file).
I created a variable named 'Set Pipe Counter' and included this variable in the 'Pipe Counter' advanced formula. The displayed 'Pipe Counter' value can now be set by altering the 'Set Pipe Counter' variable.
LIMS data
The WITS 3 device was configured and RIS variables tagged to be streamed to the LIMS database. It was decided that the risk of data being misrepresented was high. The RIS variable tag and the tag representing that variable in the LIMS server lookup table must be accurate. This requires coordinated system management from both the Developer and Engineering sections. This is not always possible. For this reason it was decided to make use of the internal data capturing function of RIS. All variables are logged, time stamped and written to a file in the 'Jobs' folder at a 1sec rate. This file becomes available on completion of the hole, converted to ASCII and is uploaded to LIMS. Care must be taken to not exceed the buffer capacity of ~18 days of memory per hole.
Coreline and VIT Depth counters:
Canrig to write a .dll device to poll the Coreline and VIT winch depthometers. (see e-mail in correspondence file). ODL to provide the RS 485 data format for meter when available. ODL purchased two Redington counters which should be delivered at the Yokohama port call.
Compensator stroke indication:
This variable was obtained by breaking into the ODL 'Compensator stroke indicator' 4-20ma signal. Modification was done and diagrams updated accordingly. A 4 - 20ma signal is provided for a 0 to 20 ft stroke. As the Compensator piston moves up and down, oil above the piston is displaced back and forth through a restriction into a reservoir. The level of oil in the reservoir and therefore the head pressure, is inversely proportional to the compensator stroke. The RIS system converts the pressure signal into a displacement signal for display and Depth tracking. The actual calibration values for Exp321 were 3.4ma to 20.25ma for 20 to 0 feet rod displacement.
A shortcoming of this measurement is that due to the inertia of the oil, ship heave causes head pressure changes which the RIS interprets as displacement. This error is significant and greater than the heave we are attempting to compensate.
Below see a graph of Heave signal (blue) versus Compensator stroke position (violet), with the compensator fully retracted and locked. (no rod displacement)







The Compensator stroke indicator was meant to provide an indication to the driller of the compensator stroke position and will not be suitable for Depth tracking. It is suggested a laser device is sourced for doing the Compensator stroke measurement.

Tracer Pump:
Tracer pump was configured to be remotely controlled via RIS. This is done via a Ethernet/RS-232 converter IP 192.168.1.5 from the Master PC, serial port (COM 6). Two Tracer pumps are installed in the mud-pump room. Only one tracer pump to be switched on at a time.

MRU Setup:
The MRU mounting was slotted and physically adjusted to within a degree for Pan and Tilt. Configuration was done with the new MRC software. Lever arms were entered to compensate for MRU position relative to the measuring point. The three analog outputs were configured from +/-10V to 0 to 10V signals. This allowed us to free up 3 analog input ports on the RIS system.

This is a summary of all the parameters configured in the MRU.

Core on Deck indication:
Historically a Coreline Depth overlay on the Rig floor video provided an indication to scientists and techs of when core would be on deck. Coreline depth was not available on Exp 321 yet and there was a real need for some sort of indication. I created a variable called Core on Deck which was scaled to the Coreline Tension variable. This gave a number, 0 on deck and ~30 at 4500m, which gave some indication of when core would be on deck. Scientists and techs became familiar with this and should suffice until Coreline Depth becomes available.
Coreline Depth video overlay:
A plan and hardware for providing this function is in place. RIS will output the Coreline Depth signal, when available, via WITS to a server. This could be the WITS device currently streaming data to LIMS. The Developers will provide code to parse this WITS signal into a serial format, compatible to the Bob4 Video overlay device. This device is already T'd into the video line of the Drill floor camera in the Coredeck network locker.
RIS V-Brick display:
The monitor output on the RIS Master PC in the computer server room is connected to a device that converts it to NTSC video. This video signal is connected to one of the V-Brick channels for distribution throughout the labstack.
RIS Critical spares
The following spares are needed to provide continued service in the case of a component failure:
1 x CompactRIO Intelligent Real Time Embedded Controller
1 x NI 9425 32 Channel Digital input module.
1 x NI 9203 8 CH Analog input module
1 x MTL5015 Digital barrier
1 x Drawworks encoder

Depth tracking .
Bit Depth is a function of Drill string length, block position, compensator stroke and heave. The Compensator stroke and Heave variables are pointed to the two motion compensating variables, Motion Compensator(v72) and Motion counter compensator (v73) respectively. Motion compensation can be disabled by clicking: MENU/SETUP/DEPTH/OFFSHORE MOTION COMPENSATION. The Compensator stroke variable is currently taken from a source with an uncertainty approximately equal to the heave. It is planned to eventually replace this measurement with info from a laser device.

Exp 321

Summary
The cruise started with a busy portcall consisting of video of ship tours and photographing evening presentations by the 320 cruise participants and VIPs at the Marriott in Honolulu.
The duties of the imaging specialist have changed considerably from the past. Rather than processing film and making prints we now inspect each section image file for accuracy, calibrate imaging equipment when required, shoot close ups when requested, produce public relations and general informational images as well as shooting and editing video.
On this expedition I have done no video since a videographer, Maarten in 't Hout, working for Ocean Leadership has sailed. We will have access to all of the video he has shot during the expedition. This will change after our stop in San Diego when Maarten will depart and the School of Rock and Leslie Peart come aboard. I anticipate shooting video as well as stills for the next ten days of transit to Victoria. I have inspected all of the section images for accuracy, taken close-up core images as well as cruise related and PR images. I also worked the catwalk for core recovery.
Equipment performance and special projects
At the beginning of this expedition one of the first tasks was to upgrade our OS to 10.5.4. This upgrade was required so that we could install new application software for our Hasselblad camera system. This application upgrade gives our equipment greater versatility. Both the new OS and application were installed with no problem and subsequently we have loaded another upgrade to the Hasselblad application.
Installing the new OS also required that a new driver for our Epson 4800 printer be downloaded and installed.. This was accomplished with no problem and gave me the opportunity to build new ICC profiles for the material that we generally print on as well as getting to know this particular printer and application. A CD of this driver was burned as a backup.
The Metz strobe for the Hasselblad which is supposed to work in TTL ( Through The Lens) metering mode doesn't. After checking on line this has been found to be the case with all of these units. The unit can still be used but not in this mode. A fix in the future may be available.
The Hasselblad, which runs on rechargeable or replaceable lithium batteries has a problem when using the lithium batteries. The batteries only last for about fifteen exposures before you start to get a low battery warning. The batteries at this point are quite hot. I will contact Hasselblad about this but at this time I recommend not using the lithium batteries.
The Section Image Logger has functioned well all cruise. There have been no equipment or software problems related to this instrument. Any difficulties identified with images have been due to human error. These errors, such as multiple images of the same section, missing section images, and moved rulers, have been identified by my daily inspection of all section images. All errors have been corrected. The application that allows me to bring the image files from the server to my machine for inspection failed to function for about two days. I told David Fackler and he corrected the problem and it has worked well since.
I received a message from Rakesh Mithal that I was to begin using Cumulus for image tracking. It took several days to get it set up for me to have access and I was signed up for a web class that took place on 6/16. Our connection was so poor, audio and screen out of sync and poor quality audio, that it was not worth staying for the class. Another class was scheduled for the following Monday.
Several close ups where shot. There is no facility to get these into the database at the present time so I will handle these as we have done in the past by burning a CD and archiving them with the other image data at IODP.
1840 core section images were inspected for quality and accuracy. So far 1476 PR photographs have been taken. I anticipate a sizable number more with the School of Rock as well as video.

Exp 321T

For the School of Rock I shot video interviews with each of the teachers and edited them into a DVD for Leslie Peart. I expect another round of this before Victoria.
I set up and recorded the re-entries and cementing at Site 1301A and B for Andy Fischer. I then edited these and made a DVD for him and David Divens.
I help Cheih indentify gas lines, install valves and track down leaks.

Publications Specialist Report

Exp 321

Debbie Partain
Summary
Provided administrative support for port call and throughout the expedition, maintained communication and provided support to shore-based staff and Publications Specialist on board the Chikyu, prepared Core descriptions and core summary plots, collected volume volume material for shore-based preparation.
Strater update:

  1. A step forward: the scientists did some work using Strater. They downloaded the track data into a Strater template for quick review. This helped resolve the problem of having to pull core from the reefer to rescan for better reflectance data.
  2. The lead sedimentologist uploaded data once a day (before I come on shift). I updated the Strater file each morning and took the printouts to the core lab. I also placed the Strater file on the server for the scientists to review. There was a 24-hour lag between the time the first core is described during the day, to the time the core description is generated. This did not seem to be a problem because the track data was available upon demand.
  3. Lithology; the sedimentologists were creating new lithologies each day. Example: Radiolarian nannofossil ooze, radiolarian diatom ooze, nannofossil diatom ooze, diatom radiolarian nannofossil ooze, etc…..I discovered that if a lithology is missing from the scheme, Strater substitutes in the first lithology described in that core. You can't just look at the borehole display to tell if the lithology is correct. It has to be cross-checked with the data. After I identified and created the new lithology in the scheme, the pattern would display correctly.
  4. We discovered that Chris's program puts an extra space after the lithology name. I cut and paste the name from the Excel file when I create a new pattern in the scheme. This way I make sure the spelling, etc. matches the name in the table.
  5. Creating a Lihology table: because of the numerous new lithologies created each day, I found it easier to make a new lithology table each time I updated the data. I deleted the old table and importd the lithology data without checking the box "import data into current table". Strater automatically created all of the fields. You will have to remap the column in property inspector under Percentage log properties/Percentage fields.
  6. It is so much easier if the schemes are shared across the holes/sites. I build on the previous schemes and replace them each time I made a change.
  7. Later in the expedition it was decided the to combine the lithologies. This was done through the schemes in Strater.
  8. The core description legend should be created along the way and given to the sedimentologists along with the core description printouts. The legend should also be used to proof data.
  9. Conversion of core descriptions to PDF can not be done until the files are complete. The Bitostrat data was uploaded late in the expedition, holding up conversion of the files.


Problems encountered
Core description preparation- The export of data from LIMs to Strater continues to be problematic. DescToStrater was hard coded specifically for the way the Exp 320 scientists entered their descriptions into DescLogik. DescToStrater must be customized for each expedition. There was little support for this on Exp 321. To compensate, I had to find alternatives for the export and import of Exp 321 data into Strater. This included export of multiple spread sheets, overlaying columns in Strater and using schemes to filter the data, and having the scientist manually filter track data.
Conversion of core descriptions to PDF can not be done until after the files are complete. The Biostrat data was uploaded late in the expedition, holding up conversion of the files.
These following problems were discovered too late in the expedition to fix on the ship.
1) Smear slide data export for both sites was incorrect and will have to be imported from a spread sheet generated separately and manually filtered.
2) U1338 Radiolorian data could not be exported and will have to be done at a later date.
As things stand, the time required to prepare and proof the core descriptions would be prohibitive on a higher-recovery expedition. The export from LIMs must be improved and the data must be reliable. This should be considered a high priority.
Mac server problems- Mac users had sporadic problems with copying files to/from the server.
Color copier – many of the problems with the copier are due to mismatched settings in the paper tray. The wheel on the tray must be set to match the paper size/orientation in the tray. There is also a lever on the wheel that indicates inches or metric. The lever needs to be pushed up for inches. The copier is not set up to print A4. It will flash an error, waiting for someone to load the paper tray. Cancel the print job and resend with the setting for letter-size paper.
Suggestions for Expedition 323
Collect passports no later than 24 hours before leaving port.
Check that the dates on the PAX spread sheet do not change when cutting and pasting from a Mac file on the PC. Do this before sending the file to the radio operator(s). They use a PC and this has caught them off guard, You can fix this on the Mac by doing a copy/paste of the columns with dates into a text editor (e.g. BBEdit), save as text, and then copy/paste from BBEdit back into the Excel file.

Exp 321

This was my inaugural Expedition as the UW MLS. In some areas it was a learning experience, in others it was getting re-acquainted w/ systems that I had worked w/ before, but enhancements had since been done. Data Summary Expedition 321 consisted of three transits, two sites and eight holes.Transits: Honolulu to PEAT 7C (L1T)PEAT 7C to PEAT 8D (L2T)PEAT 8D to San Diego (L3T)Sites:U1337 (A/B/C/D holes) & U1338 (A/B/C/D holes)Eight site fixes performed & two PDR depths observedAs was in Expedition 320, no underway watches were conducted by the IODP technical staff, except for occasional monitoring by myself. When on-site, when I was off-shift, ALO Steve Prinz monitored the systems per my instruction. This worked out well.For a reason undisclosed to me, navigation data for Expedition 321 is catalogued in the LIMS under Expedition 320. The Application Developers are aware of this. Equipment Performance Summary WinFrogWinFrog1 was used for navigation acquisition for the transit to our drill sites from Honolulu and site fixes. Two crashes were observed. WinFrog 2 was used for navigation acquisition for our transit to San Diego.The power settings on WinFrog2 had to be changed so sleep mode/standby was disabled. GyroNMEA GYRO #3 from DP was the gyro used for the duration of the Expedition.We are still having problems with the initial startup of the WinFrog PCs (1 & 2) while the DP GYRO is plugged into COM6. The mouse exhibits erratic behavior and the Windows start button utility opens and closes randomly. A couple of reboots are usually required and then w/ WinFrog running, plugging in the GYRO to COM6 usually works. The I/O device has to be added to the vehicle but that is simple enough.For about a shift we lost connection to DP's GYRO. The Transocean ETs traced it to a problem in the ECR that was quickly repaired.
Trimble/Ashtech GPSThe Trimble GPS was the primary GPS used for the duration of the Expedition. No problems were encountered. The Ashtech GPS unit was available as a backup. Bathy 2010This was new software to me as the only training I had was w/ Kristin during port-call cross-over. It will take some time to come up to speed on all its features. Maybe some of the problems encountered were due to my inexperience in troubleshooting problems w/ the software. Time will tell.At the beginning of the Expedition I was having quite a bit of problem acquiring a digitized depth with the Bathy software. I primarily used the 3.5kHz transducer for the acquisition of data this Expedition. I initially started w/ the Auto All option, allowing the software the select the appropriate gain for bottom profile observed. I didn't have much luck w/ this feature so I began to cycle through the gains for an appeared bottom. I began to have luck getting a nice bottom profile but the software was not digitizing a depth. The depths were very sporadic. I sent in a request for help to SyQwest and they recommended changing a few of the acquisition parameters:operation mode:FMpulse window:hammingsweep bandwidth:4(was set on auto)power level:0detection threshold:5 - medium(was set on 1 - highest)It took awhile adjusting the gains to lock onto a depth, but once locked on the depths have been very consistent.Since trying the bottom zoom during the early stages of the Expedition I have yet to get it to work. I either get a completely blank (black) window or a vertically stripped window w/ a white background. I have been sending screen pictures, registry settings and odc files to Syqwest but no luck as of yet (as of this writing). They suggested turning off the virus scanning software and I tried this during the startup for L3T but still no luck. SyQwest also suggested trying another PC (w/ com ports configured) running the Bathy software. I am going to try this either near the end of this transit or at the start of our transit to Victoria. On-going.
Update: SyQwest gave instructions on removing the prior software, editing the ODEC
registry files and re-installing the software. They suspected a corrupted registry. The
Bathy 2010 software was removed, HKEY_CURRENT_USER\software\ODEC was
deleted and the Bathy 2010 software (v.10910D) was installed. The configurations were
all changed to reflect the prior setting and now the both the normal view and bottom
zoom features are working great. Syqwest has been very good in their response turn-
around and I am very impressed w/ that.
One interesting note about sending information to SyQwest. They have an FTP site set up so that users can upload their data files to:
ftp.tech-graphics.comlogin: syqwest:password: #syqwest1
Just create a directory using "your name", "ship name" or "company name" and place the files in that directory. Then e-mail them w/ information to the nature of the data transfer. For some reason there was not a network cable attached to the Bathy PC. Furthermore, ports on the UW switch were disabled so I had to get an MCS to enable port access so I could put the Bathy PC on the network to transfer files and back up data. During the transit I am going to look at running a video and mouse/monitor cable under the floor or through the ceiling to facilitate viewing the Bathy system in the area of the Winfrog/seismic systems. The current monitor and mouse are not very good. EPC recordersThe EPC recorders were not used during the Expedition for prime data collection. I am seriously thinking about making sure that they are operable, by connecting and making sure that a bottom profile can be observed w/ the 3.5 & 12 kHz transducers. MiscNear the end of the prior Expedition the A/C in the aft areas became non-functional, forcing the shut down of all systems in the UW lab. Aside for cross-over, the systems remained off during the start of this Expedition until the A/C was back on (May 10). It took about four days for the repairs to be made. But it still remains that occasional shut-downs of the A/C raises the temperature in the lab to the high 90s. On one occasion the systems had to be shut-down for a day.During the L1T event from Honolulu to our first drill site, it was decided not to go to PEAT 5C but instead head to PEAT 7C; this event is recorded as L1TB. Events L1TC & L1TD are event restarts after a WinFrog crash.In coming up to speed on all the SOPs for the UW MLS, I asked the Operations Superintendent about the range of time to use for our site fix. For the first one, I was using the time of the first core on deck to the hole's last, as a window for the fix. But he said a better window would be from core 3 on because they ALWAYS pull clear of the sea floor between cores 1H and 2H. Special Projects: During either the transit to San Diego or Victoria I am going to install some cabinets and shelving in the lab and try to clean up some of the hardware in the racks and drawers under the counter.

  • Set DIP switch settings 1-7 to OFF
  • Set DIP switch 8 to OFF for paper and ON for film media
  • Channel A & B settings:
    key/scan – STBY
    Delay – 0
    Threshold – MAX
    Trigger level – INT
    Gain – 0.0
    Sweep direction - ->
    Print polarity – CENTER
    Take up – ON
    Scale lines – OFF
    External rapid – INT
    LPI – 200
    Contrast – MAX
    Channel A
    B. LPT cable
  • 25 to 25 pin end-to-end
    C. Bathy PC registry settings
    HKEY_CURRENT_USER\SOFTWARE\ODEC\Bathy2010\Custom
    EpcLabsContrast – default value is 0x32(50) or 50%. This works best.
    EpcLabsDriver – default value is 0 (not enabled). Change to 1 (enabled)
    EpcLabsGrayLevels – default value is 64 (number of gray levels). This is the highest
    quality setting and should be used.
    EpcLabsRampTest – default value is 0 (grey lightbulb). Leave it so.
    EpcLabsLinesPerInch – default value is 200. This works best.
    D. I/O port driver
  • Under C:\Program Files\Syqwest\Bathy2010 there will be a file RegOpener.exe. Execute the file. If the service has not been started, you will get a message "SERVICE HAS BEEN STARTED" or if it was already started, you will get a message "SERVICE ALREADY RUNNING".
    E. Bathy2010 software
  • go to Edit -> Configure Thermal Printer
  • check enable Thermal Printer
  • choose the correct thermal printer from the drop-down list: EPC Labs/9800/9802
  • click OK
    I am currently getting the following error.







    and on the EPC printer the Channel A & B lockout lights come on.
    To be continued…(as of July 1, 2009)
    Special Projects
    A WinFrog cookbook was started. It was a good practice for a new Tech to accomplish. I would like to get Kristin to take a look at and edit at will. It is stored in \\Vol1\IODP_Share\UW\WinFrog_cookbook.doc.
    Some semblance of organization in the lab was attempted. A cabinet was installed and boxes stored on a top shelf. It still appears that everyone's personal stuff and various work knick-knacks gets stored back there and I would like to see an end to that practice.

    Summary
    The G-gun cluster was used as the VSI seismic signal source at both site locations. There were no problems. Guns were rebuilt and pressure tested during transit.

    Special projects
    Started fabrication of side covers for the gun deployment crane.
    Overhauled PD-5 series valve and returned to spares. Valves, over haul kits, as well as replacement stems and handles are on order.

    Problems encountered
    Replaced the port side regulator poppet valve seal.
    Another older PD-5 series valve was condemned and retired due to cracks.
    As noted on Exp-320T, many valve seats throughout the high pressure air system were damaged by the shipyard during installation, fitting and welding. None should be trusted!

    Miscellaneous
    Injector pump valve spares are on order.
    Replacement bolt/chain cutters are on order.
