IODP Expedition 361: Southern African Climate - Agulhas Current Density Profile

The objectives of the expedition: The Sumatra Seismogenic Zone expedition (IODP Proposal 837-Full & 837-Add) aims to establish (1) the initial and evolving properties of the North Sumatran incoming sediments and (2) their potential effect on seismogenesis, tsunamigenesis, and forearc development for comparison with global examples. The 2004 Mw 9.2 earthquake and tsunami that struck North Sumatra and the Andaman-Nicobar Islands devastated coastal communities around the Indian Ocean. This earthquake showed unexpectedly shallow megathrust slip that was focused beneath the accretionary prism including the distinctive prism plateau offshore North Sumatra. This intriguing seismogenic behavior and forearc structure are not well explained by existing models and by relationships observed at margins where seismogenic slip typically occurs further landward. The correspondence between the 2004 rupture location and the overlying prism plateau, and evidence for a strengthened thick sediment input section suggests that the input materials are key to driving this distinctive slip behavior and long-term forearc structure.
Operations: Leaving from Colombo, Sri Lanka, we completed a 3-day transit to our first drilling location off the west coast Sumatra, site U1480. Drilling operations were successfully completed but logging operations were cancelled when the hole collapsed. After a short transit south, drilling operation commenced at site U1481 where we successfully drilled in 700+ meters of casing. On the way out of the hole, the Elmagco brake bearing failed requiring the vessel to stop operations and dock in Singapore for repairs. After 11 days, the JR resumed coring operations at U1481 and successfully completed logging before the ship was required to return to Singapore ending the expedition.
Labs and Technical Services: Few serious hardware issues during the expedition but there were numerous small issues left over from the web service changes made on the previous transit form Cape Town.
An obvious 180¿ in the magnetic correction error was never resolved even after an intensive review of our orientation tools and methods; and, a half-day of rig floor testing. Additional information on this subject is in the Paleomagnetics report. We concluded that the orientation tools work as expected in the lab but when mounted in the APC assembly their results are 180¿ off the expected value. Further investigation is needed.
The new SRM software (based on the IMS framework) was completed during the expedition along with a full user guide. Our thanks go to the science party who patiently help us develop the program while their science was in progress.

Lab WorkING Group ISSUES

• DESClogik: Provide support for computed columns.
• We report the XYZ moments for the SRM corrected to the IODP reference frame. Why aren't we doing the same for the JR6 where the moments are reported in the instrument's reference frame? Should we not be consistence?
• Need to replace the SHIL lighting system with a single light source that can be white balance thru the entire focal depth. The current 6 light tiered system creates artifacts in the RGB data are significant when plotting ratios. A suitable lighting system will produce good photos and good RGB data.
• The WRMSL and STMSL rails are worn out and need replacing.
• We need dedicated LIMS interface for data entry at the drill shack and core entry. Too many ways to make a mistake using Sample Master.
• Wayne-Kerr resistivity equipment. Please can we get rid of this equipment? This system been used for over a decade and is taking up needed space.
• We need to purchase an expendable bathythermographic (XBT) to improve our depth correction of PDR data. In areas along current boundaries, the 1980's Matthew's Tables are not adequate and we spend a lot of drilling time taking water cores. In addition, contribute to global science at the same time!

AREA-BY-AREA SUMMARY

Bridge Deck

Hazardous lockers: Cleaned and painted the floors.

Core Deck

Catwalk

• New parts for core catcher extruder where put into use. The APC jig was used for nearly everything as the XCB is to heavy for some of our techs to manage. ALO's suggested milling out some material to lighten it.
• The electric solenoid for the saltwater flush failed. SEIM's crew where looking for parts. Do not know the final status.

Core Entry:

• The p-wave logger will need a hard-plumbed airline to the p-wave logger. We did not have appropriate materials to complete this task – stainless-steel tubing has been ordered and should arrive in time for X363. An extension has been added to the air-line assembly located above the track systems. This needs to be tapped into and a line run & secured to the NGR frame, continuing on to the actuators on the p-wave system.

Splitting Room:

• UBER SAW: The water hose that feeds the super saw blade was replaced with a larger diameter hose to increase the volume of water lubricating/cleaning the core. It was generally agreed that the new hose decreased cutting time and increased core washing efficiency.
• Everyone likes the new saw hoods!
• Removed a failed LED lite from ceiling. Plenty of light so no replacement needed.

Magnetics Lab:

• New SRM software developed during the expedition;
• New bearings, shaft material, and couples have been ordered for the SRM motor and drive assembly. We had a number of issues this trip. These parts where ordered just in case!
• All expedition long, the cold head made loud sharp clicking sounds (more than usual). We did not see any issues with boil off. A 2G service call has been arrange to replace the cold head and top off the HE.

Physical properties Lab:

• Velocity Gantry:
  • Amplifier failed on the Caliper. Using a spare pulser to amplify the received signal.
  • Modified the Velocity software to report in mm instead of meters.
• Track Systems: Updated to IMS 9.2

Fo'c'sle Deck

Chemistry Lab:

• Rainwater is finding its way into the acid hood. No obvious penetration has been found. We removed the hatch in the splitting room to inspect the mechanical trunk but could not find any sign of water. The crew smeared RTV over the deck joint …doubt that fixed it. Have not had any good rainstorms since.
• The chem lab wanted a pre-filter installed in front of the nanopure water machine. Again, we were unable to complete this project due to lack of the proper tubing. A water filter has been mounted to the sink area – once the pipe is onboard, two appropriate Swagelok fittings (ordered) need to be installed on the filter housing, along with a shutoff valve (also ordered). The filter can then be plumbed into the system using the existing nylon lines.

XRD:

• Staff working with the science party developed XRD quantitative methods (DQuant macros).
• Both mixer mills are seeing their age and we should consider a full replacement of both.
• New ceramic grinding containers where ordered as the ones in use are chipped.
• A new version of DQuant was downloaded an installed on the appropriate workstations. The previous version would not work with the licensing dongles.

HOLD

Core Reefer:

• All of the floor that could be reached was painted.

Gym:

• The plastic covers for the large Cybrex were damaged. New ones have been ordered.

Poop Deck

Underway Geophysics:

• WinFrog2 experienced numerous network drops during the expedition. A new computer has been istalled but I'm not sure if this fixed the issue.

Summary

Expedition 362 sailed from Colombo, Sri Lanka and concluded in Singapore. We drilled in two sites; water depth was approximately 4,100 meters with over a kilometer of penetration; total core recovery was around 1,047 meters (54% recovery).
Due to a failure in the draw-works braking system, we had an unscheduled emergency port-call in Singapore for repairs. We lost 11 days of operations due to the transit length and time in port.
This was Keith DuPuis's first expedition as a core-lab technician. This was Brittany Martinez's first expedition as Curator.

AMS/Inventory

• Physical counts performed on UTS store room
• Many items were consolidated and moved into drawers or re-shelved. New locations are noted in the Aisle/Rack/Bin column.
• Items in the UTS that are no longer used or not on inventory were identified and a request made to have them removed. In addition, a request was made to reduce ROP/SL for many items and have overstock sent home for storage.
• Rope was moved to the TBULK area, giving us more space in the UTS.

Special projects

• Painted most of the hold reefer floor.
• Painted the floors in BHAZ and BFLM.
• Bill Mills would like an airline hard-plumbed to the p-wave logger. We did not have appropriate materials to complete this task – stainless-steel tubing has been ordered and should arrive in time for X363. An extension has been added to the air-line assembly located above the track systems. This needs to be tapped into and a line run & secured to the NGR frame, continuing on to the actuators on the p-wave system.

Special notes

• First cruise out of Cape Town tie-up period.

CORE LAB

TECHNICAL STAFF

Summary

New XCB and RCB jigs for the core catcher were used with the Arbor press. A larger diameter hose was installed on the super saw to increase the volume of water when splitting cores. There were no "gumming-up" issues with the Zebra label printers.

Equipment Notes

catwalk arbor press – RCB and XCB JIGS

The Arbor press was used to extract core catcher samples from RCB and XCB cores using new jigs. Some users experienced trouble with the larger XCB jig, and the shorter RCB jig was used for both XCB and RCB cores.
XCBRCBUsed for both RCB and XCBFigure 1 New RCB and XCB core catcher jigs for the Arbor Press. Both jigs were used initially, but the RCB jig was primarily used for both XCB and RCB core catchers.The square shaft on the press will get stuck in the spring-loaded flaps of the RCB core catcher. It will be difficult to remove the core catcher because of the grooves on the square shaft. The metal ingots will penetrate through the RCB core catcher OK. To prevent the square shaft of the press getting stuck after penetrating the RCB core catcher, stack a combination of ingots on top of each other. Keep adding and don't let the square shaft enter the core catcher (just the tip is OK!)

Square shaft: don't let it penetrate inside the RCB shoe. The shoe will get stuck. Ingots: stack them as you press through the RCB shoe (i.e. short one, then a long one. Let the short one fall through with the core. Raise the square shaft and slide the longer ingot through manually without the press. )Figure 2 A helpful hint for using the Arbor press with a RCB core catcher shoe: Read the captions above. Note: this photo shows an APC core catcher shoe. (Photo courtesy of Exp. 361 Tech. Report.)

zebra label printers

There were no issues with printing labels. We used new labels. This was not a high-recovery cruise.

Super saw – Changed the Water Hose

The water hose that feeds to the super saw blade was replaced with a larger diameter hose. The green coil hose (~1/4" diameter) was replaced with a clear ~1" diameter, clear hose. The idea was to increase the volume of water lubricating/cleaning the core. It was generally agreed that the new hose decreased cutting time and increased core washing efficiency.

Summary

Expedition 362 was not a high recovery cruise. The core material varied from soft sediments to basement intrusive basalts. The macroscopic template had a separate tab for the five structural geologist who sailed. Four paleontologists with expertise in planktonic foraminifera, nannofossils, diatoms and radiolarian sailed on expedition 362. Templates were created for each microfossil discipline
The structural geologists requested a specific template style. After the initial difficulty in merging their intent with DESClogik's description scheme, the template captured their data as desired. Request for columns capable of logical evaluations were made. The columns were a measure of probability and confidence in the structural observations. However, these kinds of columns are not supported in DESC, and still best done outside of DESClogik. Maggie Hastedt created an Excel macro, which Jean Wolfson ran to compute the desired column data. The computed columns were then copied into DESClogik in order to capture the data being plotted on the VCDs.
Several small bugs remained after the KTLF session on 362T. They were successfully managed by the programmers, esp. Tim Blaisdell. The issues are discussed in detail in the next section of this report.

• The SEM was well used by the micro paleontological scientists.
• The Thin Section Report Builder and Writer were used for all ship board thin sections.
• The Micropaleontology Wet Laboratory was used for all paleontological disciplines.
• BugWin was not used.

ISSUES/DEVELOPMENTS/To BE noted

DESClogik

The latest DESClogik version is 16.1.0.7

Issues

• The auto-recovery feature had not been integrated after the web services switch. The new authorizations had not been completed at the time DESCLogik was tested. It is now fully functional. DESC admins can click the recovery tab and select through the auto-saved files. NOTE, the files are saved per user, so you must have the scientist whose requesting a data recovery log in, and then an admin click the recovery tab and then enter his or her credentials in order to view the files. Another bug prevented the recovered file from being uploaded directly in DESCLogik, but this was also fixed.
• Template saves were requiring an overwrite after importing a configuration sheet, even if the template had been deleted for the expedition group or the name had not been used. The issue was fixed. DESC was looking in all the groups for the template name, and once a configuration sheet had been uploaded it was automatically saving a copy in the group "General". It now saves only one copy to the group specified upon import. This problem was related to another issue were admin changes to column widths were not being applied, because the settings were being pulled from the template with the same name in the General group.
• An admin (my) error was discovered where columns with too similar a qualified component and value entry were overwriting one another upon download. Column definitions were modified to more unique values and overwritten values were canceled. Data Excel backups became extremely useful because the recovery feature was not enabled. It is always good to stress frequent Excel data exports.
• A similar issue occurred if columns in different tabs had the same definition components. Such was the case when the sedimentologists and structural geologists wanted to comment on the same feature in a different way. It was changed so that data is stored uniquely by tab, so columns with the same definition can exist in separate tabs.
• Samples that had their depths changed in sample master, but the depths for the hole had not been recalculated, would not show up in DESCLogik upon download of that sample. Because DESC uses the depths to download data, the samples were shifted to a new depth. They show up under the depths below or above the expected location.
• If any change is made to section lengths in Sample Master the depths for that hole must be recalculated. On occasion, edited or un-canceled changes would not show up in LORE and hence DESC.
• Setting changes performed by scientist level DESC users were being saved to all copies of DESC. For example, column hides done by right clicking would prompt a save message, and no cancel feature had existed. The column would be permanently hidden in the template unless an admin resaved the template with the column reset to visible. The same problem did not exist for column hides done through the edit visibility option, however, changes were not permanent for that DESC user.
• A save option prompt has been added. When scientists make adjustments to the template, a screen prompt asks if the user wants to save the changes, which will affect all users of the template, or not save, and the changes will only be seen by the user during that session of DESCLogik, not permanently for that user. See figure below.

• The ship Value List Manager gave 2 errors upon upload at the beginning of the cruise, which were resolved, partly with the help of Tim Blaisdell and partly on their own. Screen grabs are included below. Though a double check of the sublist removed trailing spaces, the errors persisted. The Excel function "Trim(String)" is helpful in removing spaces before and after text, but does not remove spaces between words.

!worddav474244b4621cc3cd1f43b8469533b085.png|height=126,width=261!Tim Blaisdell changed the error message default to remain on the screen so the message could be read; it was disappearing after 1 second. The error messages are shown below.

• • The message that appears when a list/sublist with no changes is uploaded used to say "no updates were needed." It has been changed by the other corrections, and now display as shown in the figure below.

Developments

• A new version of DESCLogik was released after our second transit to site U1481, by Tim Blaisdell, 16.1.0.6. It reduces download times up to 1/3 of the previous time. Two bugs were identified and corrected after its deployment; the auto-populate feature was disabled and the bracketed references were showing up in the cells.
• Testing was done with Excel exports comparing data downloaded before and after the deployment, and the data appears to be identical. Some empty cells may be inserted in the Excel export file after the last entries, which changed the size of the file slightly.

• A concatenation feature for any columns in DESC has been created, called concat. It allows any number of column entries to be joined, just like the lithology columns. The feature is under the create formula option, which can be added to a column by right clicking the column in DESC, or in the configuration sheet. A screen grab is in the figure below. To add spaces between values use single quotes around a space, e.g. concat([column1],'',[column2]), also as shown in the figure.

• To speed up the process of creating paleo template configuration workbooks, I have added all the species from each value list to Excel workbooks, by fossil discipline. Each workbook contains an Excel command button (macro) that finds the species inputted by the user (formatting is ignored) and adds them together in the second sheet with all the pertinent template configuration sheet values.
• The user need only copy and paste the desired species list into the first column of the first worksheet and click the button. Any trailing spaces will clipped and the expedition species list is compiled in the 2^nd sheet in the order of the inputted list, and all species not found are placed in the first column of the 2^nd sheet. Duplicate values are highlighted in lite red. If the user wants to sort the species in alphabetical order, just click the button in the 2^nd sheet, "Sort My Species." The compiled list can then be copied and pasted directly into the DESC template excel configuration sheet. The Excel sheets and a short user guide are located in the All Things DESC folder, in the following location; V:\IODP_Share\ALL things DESClogik\Paleo Config Ready Species

For future expeditions, anyone can add species from their expedition templates to these workbooks at the bottom of the list on the first sheet. I have backup copies saved in my folder on IODP Share at in the following location; V:\IODP_Share\deloach\Sample Codes\DESCLogik.

• The radiolarian paleontologist Sarah Kachovich has given me a digital copy of the result of a recent radiolarian conference where all the species name conventions and descriptions were brought together and updated. It is a complete reference for all known radiolarian. There are individual papers in pdf, as well as a searchable feature by categories if we have the correct program. I have included it in our reference library in the All Things DESC folder; V:\IODP_Share\ALL things DESClogik\References\INTERRAD DIGITAL LIBRARY.

A copy has been included in data1/10.1 Core description.
I will mention it in an e-mail once I get the program details from Sarah.

• I have added the Part II to The Smear Slide Atlases reference folder. The reference slides will be locked in the top drawer of the microscope lab, across from the SEM. As a cross over note, how much should these be pushed as a description scheme for core description lab?
• I stuck with the convention of renaming the value sublists with admin name and date. Zenon agrees it is not needed since the VLM tracks these changes, but I thought it best to discuss at cross over.

BUGWIN

Bugwin was not used during this expedition. Bugwin was offered to the paleo-scientists prior to the first site. They were not interested as they did not do any species counting

PALEONTOLOGY PREP LAB

• The sieves are located in the usual spot in the Paleo Lab. Other larger and more specialized (miscellaneous) sieves can be found in the Upper Tween storage in cabinet 20D-6, back left corner, and new sieves are in 20D-3. If the miscellaneous sieves are requested by scientists please let the ALO know that these sizes are being used, so if need be we can order more.
• Another discussion this expedition was about BORAX vs. CALGON for cleaning/disaggregating the foraminifer sediment. The scientists requested CALGON because it is 'cleaner' than BORAX. There is no perfect cleaning agent.
• A large number ~50) bottles of hydrogen-peroxide was used. There are still some 70 bottles left. We should take the oldest bottles first since some of the labels are coming off.

Thin Section Report Builder and Writer

As is now the standard, thin section reports were created for all thin sections descriptions, and all viable thin sections were described in DESCLogik. Some of the softer sediment TSBs did not produce viable thin sections. It is recommended that if a TSB cannot make a viable thin section, the thin section tech still input it into the database as a thin section, and then cancel it with a comment explaining why the TSB did not make a viable thin section. The curator, imaging tech, DESC tech, scientists etc., will go looking for these, and without a clear trail as to what happened to the TSB, they will be confused. If Chad has a protocol please share this with the thin section tech, and me, at the next crossover.
Since the label etching can be difficult to see when oil is used in the cover slide, Susan, the thin section tech, has begun adding Bradey labels to the slides to better identify them. This is very useful and hopefully will be passed on to Seth Frank.
Peter Blum has created a user guide for the TS Writer/Bldr programs, which is located in the All Things DESC folder under TS Report Writer/Bldr. The user guide contains a tutorial that utilizes an Excel workbook that can be pulled directly from the user guide, or there is a copy of it in the folder. I have added comments and sent the document back to Peter. He has yet to reply. There are two key points to remember when using the user guide example reports. The image ASMAN IDs need to be changed to ones uploaded to the TEST project, or to TS images produced during expedition, or deleted for the example reports to print. Also, his example workbook book needs to be reset in the TS Builder. Refer to my comments on the edited draft in the DESC folder, file name ts_report_ug_20160920_deloach.

SEM

The SEM and sputter coater saw good use during this expedition. The Argon supply line regulators for the sputter coater are a little confusing, but basically only the highest knob should be used to adjust the pressure. The pressure should then be checked by using the smaller lower regulator's gauge. Since there is a leak inside the sputter coater the Argon needs to be turned off after use. The lower pressure gauge should fall to zero shortly after closing the on/off valve. If it still shows pressure then the upper regulator is not open enough to allow Argon to flow.
The SEM filament was changed midway through, using the thick binder manual, instructions tabbed with post it note slips. The spare filaments are kept in the XRD Lab safe. A beam axis alignment was also performed with instructions in the same tabbed binder.
We are now under the restock limit for filaments, Lisa Crowder knows there are 4 remaining on board.

Data Backup

• All DESClogik data was exported to excel and saved on a hole-by-hole and template-by-template basis to data1/10.1 Core description.
• All smear slide sheets were scanned and saved to data1/10.1 Core description.
• All SEM files (jpg, tiff and txt) were saved to data1/25.1 SEM and uploaded to LIMS (by the scientists).
• In order to sink all google value lists on ship/shore all current value lists (main and sub), were copied from "All things DESC" on IODP Share to data1/10.1 Core description.

MAGNETICS LAB

BETH NOVAK
Scientists: Xixi Zhao and Tao Yang

Summary

The paleomagnetics lab was used this cruise to measure archive section halves and discrete specimens. The cores collected during Exp 362T were measured prior to coring at U1480. Approximately 370 discrete cubes were collected from working half sections and measured with JR6 Spinner Magnetometer. Specimens were demagnetized using alternating field and thermal techniques. The Icefield MI5 and Flex it tools were deployed at Site U1480 for full APC cores. The orientation data was determined to be suspect and extensive testing of the orientation tools was completed. The new IMS-SRM software was deployed, tested, and modified during Exp 362.

Issues

SRM-

• The IMS-SRM software was deployed during Exp 362. Testing was completed by technicians and scientists in an effort to eliminate all software bugs. A quick start guide and user guide have been written. These are draft documents pending review. They can be found in IODP Share: PMAG Documents.
• Testing results of the software will be provided in a separate document.
• During the 362T, Margaret noted the cold head was becoming noisy. IVC voltages have dropped (see chart at the end of report). During Exp 362 the sound grew gradually worse and after contacting Dave Schuler at 2G we decided the cold head was failing. A service call to replace the cold head has been scheduled for the 363 port call in Singapore. A helium fill will also take place.
• During SRM measurements a noise was noted by scientists and staff coming from the M-drive motor area of the SRM. The sound seemed to be worse with heavier cores and in one direction of movement. Originally it was thought to be a bad bearing. New bearings were ordered. Upon further inspection, it appears the shaft was slipping. The set screw was tightened further and the sound has been reduced drastically.
• Preparations for the new helium free SRM have continued. In particular the SIEM electricians installed an MCT in the floor between the load zone and desk space. This will be the conduit for running the 3 phase power for the SRM compressor.
• SRM motor was close to overheating (47 degrees C) so the protective plexi-glass shield was removed to allow more air flow.
• The SRM files have changed format. LORE and MUT were updated to accommodate these changes for both discretes and section halves.
• The SRM PC was found to be running very slow for simple functions. A new PC tower was installed in the lab prior to coring at Site U1480.

Orientation Tools-

Orientation Tool Testing Results

Purpose of Experiment:

During Exp 362 a question arose about the quality of the orientation data. The scientists could not use inclination to create a magnetostratigraphy due to the low latitude of the drilling sites and therefore opted to use Declination values to determine the magnetostratigraphy. The declination was expected to be near zero for the most recent sediments. The values, after correcting for orientation resulted in values near 180 degrees. This result would be interpreted as an age older than the Bruhnes Chron, which disagreed with the data from the biostratigraphy and ash ages. Upon request, further investigation into the error was started.

Prior to Rig Floor Testing:

Possible sources of the error:

1. Malfunctioning Tools
2. Software error with IMS-SRM
3. Incorrect orientation picks or application of corrections
4. Incorrect tool deployment

• The problem was noted in Icefield tool 2007 data from U1480B and E, and therefore we opted to run the Flex-it tool 0937 at Hole U1480H in order to compare results at the same site from the same depth. The two data sets appeared to agree (Figure 1 and Figure 2), both showing a declination of 180 degrees off from the expected values. This test led to the conclusion that the Icefield tools were not malfunctioning.
• The new IMS-SRM software was checked to ensure the data was not being reported incorrectly. Handmade standards were created with magnetic tape and paleomagnetic cubes. A field was applied on 1 axis of the cube. Three cubes were made in total, one with a field on X, one with a field on Y, and one with a field on Z. The cubes were measured in the JR6 and then in the SRM. The data between the instruments agreed. This test led to the conclusion that the new IMS-SRM software was properly calculating the declination and inclination for the specimens.

Figure 3-U1480H Declinations after correction. Orientation data was collected using the Flexit Tool 0937

• The orientation picks, selected by the technician based off of standpipe pressure data, time on deck, temperature downhole and data quality (ie are the magnetic tool face values stable?), were rechecked. There were no errors in the picks or the calculations of the average magnetic tool face for each core. The LORE report was compared to the raw calculations to ensure all data was uploaded and assigned to each component properly. No issues were found.
• The next item checked was the tool setup on the drill floor. Because each piece is keyed into the next piece of the assembly, it is difficult to impossible to reverse any of the assembly. The Flexit and Icefield tools are keyed into their pressure housings and the pressure housing key into the tensor pressure case on the drill floor. A tapered pin is inserted into the assembly to secure the assembly further. The hole in the liner is always drilled in between the working lines on the core liner. But there was no way to check that the hole was drilled properly on the cores in question.
• In order to ensure that each of the orientation tools were functioning as expected, in lab tests were conducted. The tools were aligned with magnetic north and then rotated every 2-5 minutes 90 degrees clockwise, then they were rotated counterclockwise to 240 degrees, 160 degrees, and 70 degrees and finally returned to North. Results are shown in Table 1. These results indicate that the tools magnetic tool face is the face of the tool we expected it to be.
• Table 1- In Lab Rotation Test ResultsBased off of these early tests the decision was made to set up the orientation tools on the rig floor and ensure that our understanding of the tools frame of reference, tool deployment, and data reporting are correct.

Assumptions:

Figure 4-Relationship between IODP coordinate system, magnetic tool face, and core liner.Per IODP documentation:

• The values reported by the orientation tools is the difference between the Magnetic Tool Face (MTF) and Magnetic North.
• The MTF and the double line on the core liner are aligned.
• In the IODP coordinate system, the MTF points in +X direction (Figure 3).
• The ship's steel structure will influence the results to an unknown amount.
• The tools where suspended in the derrick. We assume that the surrounding steel will distort the local magnetic field.
• The ship's heading was held constant so it is unlikely that this distortion changed during the experiment.

Experiment Setup:

• A fully assembled APC coring system was suspended in the derrick. The tool was passed through the rigfloor with about 18" of core liner exposed at the moon pool door (Figure 4)
• A spatial sensor (3 axis magnetometer and accelerometer, Phidget model 1056) was mounted just inside the liner and aligned to the double line. This was meant to act as an independent means of recording the rotation of the APC assembly. Unfortunately, it did not survive the environment under the rig floor to be of any use (Figure 5).
• Figure 5-Core Barrel and Working Half Liner in Position over the Moon PoolAn acrylic ring was fabricated and the laser engraver was used to scribe lines at 10 degree intervals. We the mounted the ring to the outside of the core liner and aligned it with the center of the double lines (Figure 6).
• A pointer was mounted to the handrail to mark the ship's heading (Figure 7).
• Starting at our zero mark on the ring (=ship's heading), we made four 90 degree rotations clock-wise and four counter-clockwise rotations.
• At each rotation, the staff held the APC assembly steady for 2 minutes. We were underway at the time and the ship had a slight roll causing the tool to shift during the experiment (Figure 8).
• At each rotation, the start and stop time (local and GMT) was recorded.
• We synchronized both the Icefield and Flexit tools to GMT time.

Figure 9-Red Pointer used as relative reference for rotation. Image on the left was taken during set up. Image on the right was taken during the experiment. Note the C-clamp in the right side image being used to steady the core barrel.

Processing:

• The data from both tools was downloaded immediately after the completion of rig floor testing.
• The Flexit data files were processed using MeasureIT and the Icefield data files were processed using Inclin.
• Each time period in which the tool was held stationary was identified. The average magnetic tool face for each time period was calculated. These periods of time were identified in the Flexit .svy file and the Icefield .prn file.
• Data collected by the WinFrog Navigation system, showed that the ship held a steady heading of 273 +/-2 degrees during the measurement period.
• Local magnetic declination for our location (N6¿30' and E97¿35') is 0° 30' W  ± 0° 16'  changing by  0° 2' E. The local magnetic declination does not appear to be a factor in this experiment.
• An average magnetic tool face value, the angle between the magnetic tool face and magnetic north, was calculated for each station. Results are summarized in the results section.

Results:

Table 2- Summary Table- Assumed direction is based from the ships heading of 273 degrees and rotations of 90 degrees.









Table 3- Flexit Results- True angle of rotation is equal to the difference between average MTF values of each sequential station. The difference from expected column is equal to the difference (in a clockwise direction) between the assumed direction and the average magnetic tool face (MTF) angle recorded. Negative values indicate counterclockwise rotation of the tool.

Table 4-Icefield Results- True angle of rotation is equal to the difference between average MTF values of each sequential station. The difference from expected column is equal to the difference (in a clockwise direction) between the assumed direction and the average magnetic tool face (MTF) angle recorded. Negative values indicate counterclockwise rotation of the tool.

Conclusions:

• The Flexit and Icefield tools respond to rotation in the same manner.
• Clockwise rotation produces increasing magnetic tool face values
• Counterclockwise rotation produces decreasing magnetic tool face values
• Magnetic tool face for the Flexit and Icefield tools is in the direction of the opening where the keyed pressure barrel end piece fits into the tool.
• There is no difference in the deployment of the Flexit and Icefield tools
• Given the errors from hand rotating and securing the APC assembly, both tools gave nearly the same results. There is no difference between the Flexit and IceField tools concerning how their magnetic tool face relates to the APC Assembly, or how values respond to identical rotations.
• Both tools have an average error of ~151 degrees from the expected value during the rig floor testing.
• The tech note 34 notes on corrected declination are correct. Declination Observed + Magnetic Tool Face+ Local field variation= Declination Corrected

Further Questions:

• Is it reasonable to expect the local distortion in the magnetic field is 151 degrees? Or more reasonable to believe a 29 degree distortion and that the MTF is pointing 180 degrees from the double lines on the core liner?
• The Hall probe and Flux gate were used to check the tensor housing and pressure case for any magnetic field. No fields above the ambient lab noise were detected.

JR6 Spinner Magnetometer

• The JR6 experienced very few issues this expedition.
• Yellow foam like material is still being found within the spinner during cleaning. Agico was contacted about this issue. Response from Agico:
• It seems that dumping foams in your JR6 are disintegrated. This usually happens after few years in hard climate. Unfortunately, it is not possible to somehow protect the foams. It will be good to clean the mechanics with a vacuum cleaner and then test the magnetometer for the vibrations. If you notice some vibrations, it is time replace both dumping foams.- Michal Almasi
• !worddavbd82e4346832184fc9da4a740bb31b30.png|height=243,width=354!A distinct 'squeak' could be heard coming from the JR6 during measurements. The source of the sound was the screw of the manipulator. A small amount (not even visible) of Lubriplate was placed on the screw and the squeaking stopped. Arrow indicates the screw that was creating the noise.

• The JR6 uploader was used successfully throughout the expedition. There were some upload issues due to various problems, such as:
  • Text ID in file entered as Cube but database has sample as CYL. This was a user error during sample entry. If the barcode scanner is used to enter the specimen names, this will not be an issue.
  • Data for a canceled specimen was included in an upload file. To fix this issue, the sample was un-canceled in LIME and the upload continued successfully.
  • The .dat file does not always export properly, resulting in misread data files.
• This uploader will undergo updates soon. JR6 Lore report and uploader updated to include the geographic coordinate Declination and Inclination. Previously the upload only included the specimen coordinate values.

Thermal Demagnetization Oven

• The central Watlow temperature controller (sample zone) indicated "A2h," during a thermal demagnetization step of 75 degrees C. This alarm, Alarm 2 high, is triggered when the temperature exceeds the high limit selected for the sensor. No one was aware that an alarm range had been set on this sensor. The alarm was cleared using the temperature controller menus and the demagnetization step was restarted. Alarm may have been triggered by a temperature overshoot when approaching the set oven temperature.
• The oven did not reach temperature properly on the run following the "Alarm 2 high" adjustment. Subsequent runs saw no issues.

Miscellaneous Lab Items-

• Discrete cubes have been relocated to the Upper Tween Store room. Space was made in the cabinet nearest the elevator for checked out trays to be stored.
• A second touch screen monitor was installed at the SRM station. This monitor will eventually move to the load zone for the SRM.
• A quick guide to Puffin Plot was written and placed in the IODP Share – Pmag Documents folder.
• There were issues with the discrete label formatting when printing on the close up zebra label printer. The Text ID was overlapping with the barcode. Attempts to fix this issue resulted in the bar code moving off the edge of the label. The issue was resolved by the MCS.
• A cheat sheet for applying fields to a cube in the impulse magnetizer was placed in the impulse magnetizer binder.
• A document explaining the arithmetic for calculating azimuth, dip, and magnetic tool face was added to the Icefield manual.

Summary

Expedition 362 saw relatively few issues with the lab's equipment. We had hardware upgrades on the WRMSL PWL system and IMS was upgraded to 9.2 on the WRMSL, STMSL, SHIL and SHMSL. Other than the tracks the PP lab was fairly busy this expedition, all instruments were run on a day-to-day basis.
All data was exported from LIMS and saved to data1 after the last samples were measured.

Individual Measurement Systems

velocity gantry

The Velocity Gantry system was constantly used to measure the all three axis velocities of split sections, pieces and discrete samples. The calipers were cleaned and couplant added as necessary.
We found a problem with the PWC report:
The Caliper column is supposed to be reporting numbers in mm with 2 decimal points. At some point, the numbers being reported changed to cm and then again to m but the unit stayed the same. The standard report has 2 decimal pts so not sufficient precision. The expanded report has 4 decimal pts, which provides enough precision if scientists know to look there.

• Caliper data appear in m as early as Exp 353.
• Caliper data appear in cm for Exp 336-352.
• Data appear in mm through Exp 335.

For this expedition,

1. The code or the uploader changed on September 23. The code prior to the section that writes the data to the load file, was left unchanged.  Therefore, calibration, configuration files and calculation sections of the code still work with a bizarre combination of cm, meters and mm!?
2. The caliper data corrected so far have been changed.

Longer term, all data since 336 need to be corrected because if we just change the unit in the header, most expeditions will be wrong.

moisture and density (MAD)

The MAD station ran without issue. We did experience one database communication error seen at the end of Hole U1480F which was fixed by Tim Blaisdell. The PP scientists performed MAD tests on all holes.
The updates made during the transit caused the following issues:

• The LORE MAD reports were showing two rows for every sample - one filled out with all the data, and one blank row with no data.
• The blank row was present because the report was showing a row for the incomplete MAD test created by SampleMaster (or MADMax) to represent the fact that the sample needs to be processed through the MAD station.  Once again this was a small side-effect of the web-services conversion.

There are two fixes for this, and we decided to do both.

• The techs and scientists using MADMax should be advised that by checking the "Done" checkbox on a sample and clicking "Refresh", it is possible to remove a sample from MADMax's list.  It is advisable that users do this when testing on a sample is complete, so that MADMax's list of samples is kept small.  This will speed MADMax up when loading/processing samples and in general take the pressure off that workstation's resources/memory/etc. 
• Clicking the "Done" checkbox also has the effect of canceling the incomplete MAD test that is causing the blank row on the reports.
• The LORE report definitions for the two MAD reports have been changed to not include the incomplete test.  This way, the empty rows will not appear, even for samples that are still on MADMax's list.

More fixes that were performed on the MadMax program:

• There was no way to cancel out of a balance test measurement.
• Tares performed as part of a balance test measurement are not retained for future measurements.  Thus, if the user wants to repeatedly perform balance test measurements, he/she must run a tare every time.

Technical Service

Pycnometer calibration was done on a regular basis while running samples.

shear strength station

The AVS system was used during the entire expedition. The scientists switched around between the different vanes. The LORE report was adjusted to kN/m² as stated in the excel template.

shear strength manual measurements

The torvane and penetrometer were both used during the entire expedition. The scientists switched around between with/without adapter foot depending on the sediment.
Also, previous version of the penetrometer software did not filter canceled samples; when canceled samples appeared in the sample-selection box it was impossible to discern between canceled and active samples.  The new version properly filters out all canceled samples so they do not appear in the sample-selection list.
The Strength manual was updated.

Thermal Conductivity

The TK04 system was used constantly during the entire expedition. The scientists switched around between the different needles/pucks. The LORE report was adjusted to indicate which results were auto-calculated ("tcon_calc" versus results from the SAM calculated results from the TEKA called "teka") by the TK04 program and the ones that were copied from the dwl-files.
The calculation for "non-SAM" results that runs in the database is the following:
  public static double CalculateAvgTC(string dwlFileName)
        {
// dwlFileName is the *.dwl file in the folder being uploaded.
            double tc = 0;
            // have to calculate the tc file instead of read them from the file
            if (File.Exists(dwlFileName))
            {
                FileStream dwlIn = File.OpenRead(dwlFileName);
                StreamReader sr2 = new StreamReader(dwlIn);
                sr2.ReadLine(); //ignore first Line
                string dwlLine = sr2.ReadLine(); // software version line
                string needleName = dwlLine.Substring(0, dwlLine.IndexOf(".ini") + 4);
                sr2.ReadLine(); // comment line
                String heatingPower = sr2.ReadLine();
                String slopeStdTLc = sr2.ReadLine();
 
                string heatPower = heatingPower.Split('=')[1].Trim();  // read heat power from file
                // reserved
                sr2.ReadLine();
                // some number
                sr2.ReadLine();
                // some other number
                sr2.ReadLine();
                //header line
                sr2.ReadLine();
                String line;
                double hPow = Double.Parse(heatPower);
                List<double> tcon = new List<double>();
                double lastT = 0, lastln = 0;
                while (!String.IsNullOrEmpty(line = sr2.ReadLine()))
                {
                    String[] data = line.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
                  
                    // Convert the Temperature read from file to a double-precision number.
                    double T = Double.Parse(data[0].Trim());
                       
                    // Convert the time read from file to a double-precision number.
                    double t = Double.Parse(data[1].Trim());
                   
                    // Convert the resistivity read from file to a double-precision number.   - not used in calculations
                    double R = Double.Parse(data[2].Trim());
 
                    double lnt = Math.Log(t, Math.E);  / Calculate ln(t).
                    if (!Double.IsNaN(lnt))  // Check to make sure ln(t) is a valid number.
                    {
                        double tcondat = (hPow / (Math.PI * 4)) * ((lnt - lastln) / (T - lastT));
                        if (!Double.IsNaN(tcondat) && !Double.IsInfinity(tcondat) && !Double.IsNegativeInfinity(tcondat))
                            tcon.Add(tcondat);  // Calculated thermal conductivity is valid, add it to the list
                    }
                    lastT = T;  // Store the time and temperature values to use in calculations next time around.
                    lastln = lnt;
                }
                sr2.Close();  // Finished reading file.
                // Calcualte the average.
                double tconsum = 0;
                foreach (double d in tcon)
                {
                    tconsum += d;
                }
                tc = (tconsum / tcon.Count);
            }
            return tc;
        }
It is still under discussion if the calculated values should be stored or not. The discussion will continue in the LWG.
The usual problem of switching between unregulated power and UPS while running the TCON appeared again. In the first part of the expedition, using the needles, the UPS was used directly without having it run only on batteries. Results were satisfying. When we switched to pucks for measurements, unregulated power worked well for a while. When the results deteriorated after that, we switched back to the UPS. At this point, the best results were reached having the UPS run on battery power only.
A software that monitors the UPS was installed on the TCON PC, so scientists and technicians are alerted if UPS power is running low.
A UPS monitoring software (SNMP-NV6 Manager) was installed on at the workstation. The program is currently configured to show if the UPS is connected or running of battery. The battery status is shown in % (Figure 1).
The TCON user guide was updated.
Figure 1. UPS monitoring software.

WHOLE ROUND multisensor loggerS (WRMSL)

Expedition 362 did not use the STMSL. The PWL hardware on the WRMSL was changed during casing of Hole F on U1480 (see Fig. 2).
Issue: Worn bearings allowing the caliper plates on the PWL to bind.  This either prevented or delayed the opening of the caliper which cause measurements to be missed or would cause the push actuator to stall.
Figure 2. PWL improvements - springs between the bearings and the instrument stand. New bearings. Solution: Scavenged bearings and shafts from the old gantry caliper and rebuilt the PWL caliper.  Because the bearings were originally handmade, we had to custom grind the shafts to each bearing set and modify the openings in the caliper plates to accept the bearings.
This worked to tighten up the shafts/bearings.  Because fit is much tighter, we had to increase the torque on the open and close moves of the Exlar. We expect the system to loosen up with use. 
In addition, we modified the IMS PWL software to ensure that the calipers open before allowing the track to move to the next section. We have now had two days without issues, and the system looks solid.
The WRMSL PWL was calibrated after the hardware change. Results from Core 1 of Hole U1480D are congruent (Fig. 3).
Figure 3. Comparison of PWAVE_L before (circles) and after (triangles) hardware change.
The code for Magnetic Susceptibility was changed to disable the range test during normal data acquisition. This test looked at the time the meter took to return a measurement. A shorter time indicates the 1.0 range and longer the 0.1 range. If the test indicate a range other than what was in the configuration file, an error was reported. When operating with other instruments on a track system, there where situations where delay on another instrument would trigger a range error on the MS. Now the range test is only done when the instrument is initialized or used with the MS utility. This change was made on the SHMSL point MS, as well.
We had a software upgrade on the WRMSL. IMS was upgraded to 9.2. This version of IMS 1) corrects several problems on the Sample Information page, 2) uses a more standard format to read and write configuration files and 3) discontinues the use of third-party libraries no longer needed.

Section half image logger (shil)

The SHIL saw normal usage this expedition. The SHIL was upgraded to 9.2. This version of IMS 1) corrects several problems on the Sample Information page, 2) uses a more standard format to read and write configuration files and 3) discontinues the use of third-party libraries no longer needed

section half multisensor logger (SHMSL)

The SHMSL ran successfully throughout the expedition, with MS point and color spectrometry measurements taken on archive section halves.
The IMS 9.2 update was installed on this track as well.

Natural Gamma Radiation (NGR)

The NGR ran nearly constantly with no major problems. Calibrations and background were established twice. The bias Voltage calibration was as follows:

IMAGING & MICROSCOPES

TIM FULTON

Summary

Expedition 362 has been a low recovery, but successful expedition. The main focus of my work was to proof the line scan images for all the core recovered, photograph all close-up requests, produce or edit the weekly photos and write the captions, produce the group photos, t-shirt stencil production and co-ordinate the ironing party, assist the scientists with microscope set-up and issues and provide assistance on the catwalk with the core retrieval.
There were issues with Capture One and Image Capture used for close-up photography. Early in the cruise McAffie virus software failed to update resulting in the close-up computer being taken offline. Upon correction of this issue Capture One began hanging up in the process of developing the tiff/jpg images. There exists an intermittent issue with the upload from Image Capture. The work around is to close Capture One after each close-up photo and processing. This allows the tiff and jpg to upload to LIMS from Image Capture.
The exposure/white balance of the SHIL was checked between both sites and adjusted as needed.

IMAGING

I used Photoshop to edit/produce images for the cruise. Image Grabber to download the line scan images and Excel to sort the data for the SHIL images. These all worked fine as expected.
A bulb was replaced in the PICAT light source. The plug appeared to show wear and may need to be replaced soon. However it worked well once the bulb was replaced.

General Duties Performed

• Generated the "mug photos"
• Downloaded and proofed all of the line scan core images.
• Photographed the close-up requests.
• Photographed and edited the weekly photo submissions and produced the captions.
• Produced all of the group photos.
• Printed the T-shirt stencils and coordinated the ironing party.
• Assisted with the core retrieval on the cat walk.

Image Files Produced

• 193 Close-ups Images
• 36 Thin-section Images
• 1013 Line Scan Images
• 41.07 GB Still Images

Microscopes

• The microscopes were set up as needed for Nannos, Radiolarian and Foraminifera in the main lab.
• The inventory of the objectives will be completed as per every expedition. There had been a lingering issue with two sets (4) objectives sharing inventory numbers. This inventory number is not an AMS type of number rather it serves the Imaging Specialist and others to keep up with locations and count.
• To close, the microscope lab equipment available and overall layout of the lab is strong and well suited.
• The microscopes will be cleaned for the next Expedition.

Issues:

Another Spot camera should be ordered for an SV-8.

CHEMISTRY LAB TECHNICIANS REPORT

LISA BRANDT & AARON MECHLER

…as of 0500 03 October

Ampulator

The Adelphi ampoule sealer was used, with no issues to report.

Balances

The Cahn C-29 balance exhibited some drifting behavior, so it was replaced with the Cahn C-31, which worked fine all expedition. No problems with the Mettler.

Carver Presses

Carver press Bill had a problem where it wasn't reaching the set pressure. Noticed what appeared to be some oil that had been leaking from the press. After adding oil to the pump, the press operated normally but there was still a slow leak of oil from the press, around the seam.

Cary Spectrophotometer

The Cary was used to analyze ammonia, phosphate, and silica, with no issues to report. The autosampler worked well. There was a rare issue where advanced reads would not recognize the autosampler, but would recognize it after restarting the program. The rinse time setting in the sampler configuration does not appear to do anything at the moment as the autosampler would uptake from the rinse for the same amount of time as the samples which was set by the fill/return time setting on the accessories2 tab. We put in a REQ for more autosampler vials and another autosampler probe.

CHNS

Total carbon and nitrogen were measured on the EA. Had problems with the low standard and could not get a good calibration curve or check standards would always come in way off from the correct values. Used the Sulfanilamide standard with no issues. The combustion column will need to be changed.

Coulometer

The coulometer was used, no issues to report.

Freeze-drier

There were no issues with the freeze-drier.

Fume hoods

Fume hood F2 (the acid washing fume hood) had some flooding multiple times during the expedition during heavy rain. Bill Mills worked with the crew and opened up several hatches to check for the source of the leak. It was not found. Keep an eye on the hood during heavy rain.

Gas Lines/manifold

No issues to report.

GC3/NGA1

Both GCs were calibrated. All headspace samples were analyzed on the GC3. There were no issues with either unit. At the beginning of the cruise, we had some issues with the MUTT data uploading, mostly problems with it only selecting one of the csv files for uploading, and then not uploading either file. We changed the MUTT version to the current one, and also increased the refresh mode to 15 seconds. I believe what was happening was that MUTT was pinging the data>in folder while Chemstation was still in the process of writing the files to that location, so it was only seeing one of the files and then getting confused.

Hydrogen generators

No issues with the hydrogen generators.

IC

The IC was used to measure cations and anions on the IW and rhizon samples. Anions and cations columns were both replaced mid-expedition after inconsistent calibrations. We had some issues with the lines from the Ultrafiltration cell on the autosampler being installed incorrectly. We downloaded a Metrohm Manual specifically for the UF cell, and corrected the tubing placement. This manual has been stored in the Metrohm>manuals folder on the IC computer. The scientists decided they wanted to try spiking the solutions with an internal standard that contained nitrate. The written correspondence from Evan Solomon and our notes are attached at the end of the report. The nitrate spiking worked well, and the scientists were happy with it. We added the field Nitrate.Area to an expedition-specific export report, and exported the nitrate areas along with the other QA/QC data.

ICP

The ICP was used to measure minor elements on the IW and rhizon samples. ICP majors were measured only one time early in the expedition. After comparing the majors data to the IC, the scientists decided they were OK with using the IC data and did not measure for ICP majors the rest of the expedition. On the last run of the expedition, we did have a problem of the autosampler hitting the side of a vial. The alignment should probably be checked. We did not run any sediment samples, and IW glassware is installed. The database is running sluggishly, you might want to archive the mdb file before heavily using the ICP next cruise. Also, I went through and "hid" all methods that have not been used since 2014, just to make the method selection window a bit cleaner. The methods can be unhidden at any time.

salinity

The optical refractometer was used, with no issues to report.

SRA

Not on board, haha!

Pipettors

No issues to report with any of the pipettors. The new repeater pipettes were used and worked well. Another repeator pipettor, and 50mL reservoir tips were REQuested from shore.

alkalinity

Alkalinty was updated to allow for Rhizon splits to be selected via the hierarchy search. The update also fixed the datalog, which is now usable and displays information for all samples that have been run.

Chloride

The silver nitrate is .0141 N right now, not .1 N. Had an occasional issue where the titrator would not recognize the end point and would continue adding silver nitrate till it would time out at 6.5 mL and would not report a chloride value. Sometimes it would just happen once and then continue normally on the following samples. Sometimes it would happen repeatedly to the point that we would restart the titrator and pc thinking that maybe something is wrong with the connection. Was a correlation at one point between having IAPSO in the current sample field and the titrator running fine, and having a sample in the current sample field and running into this problem. The devs are looking into the chloride program to see if there's anything going on there, but I think it's something to do with the titrator not finding the end point. As of Oct 2, the devs have put out a change where the CL total updates in the final value box as the titration progresses. This seems to have solved the "no final values at the end" while running a sample problem, but is probably going to cause confusion, because the titration actually titrates past the endpoint, and so it makes the CL- look artificially high before finishing the calculation and dropping the concentration back down. We will try and work more on this before the end of the expedition.

Water system

Our inventory was very low on Carbon Filters, the filter that goes in slot 3 on the RoPure unit. During week 6, the filter installed clogged. We did not have any spare carbon filters. We had already appropriated/stolen the one from thin section. The machine doesn't know which filter you have installed, so we installed an MPS cartridge in its place. The purpose of the carbon filter is to remove Chlorine from the water (we don't have any chlorine in the ship water, or at least not as much as compared to a normal City Sewer&Water setup), and also to act as a secondary particulate filter. We put in the MPS cartridge just to get through the rest of the expedition, but a real Carbon cartridge filter should be installed as soon as they arrive in the freight. We also increased the Stock Level in AMS of the pre-filters and carbon filters, to 9 of each. Basically aiming to have each ROpure unit onboard have 3 of each filter available.
We also decided we want to try plumbing our water through a household sediment filter before it reaches the RoPure Unit. We decided on this because our prefilter on the RO unit was looking very brown after only a couple weeks of use. Tim B built us a nice bracket for the household filter, underneath/next to the sink under the water units. Unfortunately, we did not have the correct swaglock to connect the water. This has been ordered.

Misc

The holders for the Dispensettes worked really well. We had Randy make us a couple more, and they are stored in the cabinet next to the spare Dispensettes. We also had a custom sample holder for splits made out of some of the 10 miles of plexiglass that was bought in Cape Town. The scientists were doing splits into multiple very small vials, and none of our current sample holders worked very well. They were suitably impressed with their custom holder. Remember to flame the edges of anything you make with plexiglass to make it look classy. The scientists did not use Squeezer #1 after the first site. It was decided that this squeezer needed to be retired because there was no water being produced from this squeezer on a sample taken from a deep depth. We personally think that maybe there just wasn't any water to be produced from that sample. I would go ahead and use Squeezer #1 but keep an eye on it. Another squeezer's piston became somewhat corroded/discolored about halfway through the cruise. Randy fixed it with some 2000 grit sandpaper (not really enough to take any of the steel off), and this worked very well, and the piston had no more problems.

Evan Solomon IC Nitrate Spiking Notes

FROM EVANWe have been measuring nitrate on our IC mainly as an internal standard for sulfate and chloride analyses. Most of the error in the Cl values are due to dilution error, hence the internal nitrate standard. However, you may be able to get good nitrate numbers on the IC from pore water, though we have not had time to really develop the method. If you have time out on the JR, below are my recommendations: 1. The standard we buy is from Merck-Millipore. It is a 1 g/L nitrate standard (16.13 mmol/l). For internal standard, we dilute to ~50 umol/L (much higher concentration than natural, diluted samples)2. If you have a standard onboard, dilute with artificial seawater. Note, in the old colorimetric method, they made stock standard from KNO3 (perhaps there is some onboard??) - When we use it for internal standard, it is added to IAPSO dilutions and samples. 3. The nitrate concentrations you are likely to observe in pore water are ~0 to 80 umol/L4. However, you are diluting the samples. If you can get by with a 50 x dilution, then the concentration range would be 0 to 1.6 umol/L6. I suggest making a 6-point calibration curve in this range and see if it is linear and whether you get good reproducibility and accuracy.Would be fantastic if you have time out there to try this. If so, please keep me posted.

Lisa B Notes:

We do not stock any Nitrate Standards. I made a Standard stock solution using Potassium Nitrate.

• 16.13 mmol/L Nitrate Standard Stock
• 1 g Potassium Nitrate to 1 L DI H20.
• 50 uM/L Nitrate Solution to use as internal Standard
• 3.1 mL of 16.13 mM Nitrate standard, to 1 L DI H20.

XRD & ICP SAMPLE PREP LABS

Nicolette Lawler

Summary

This was a low recovery sediment cruise with quantitative X-Ray diffraction performed on bulk powders to calculate the weight percents of clay, quartz, calcite, and plagioclase. Results fell in line with smear slides and helped identify different lithologic units. Scientists brought aboard a set of ten standards with known mineral mixtures. All samples were ground and mixed using the Mixer Mill with the Alumina Ceramic Vessels at the scientist request. Intensity values were lower than expected for the samples but normal when run with a Calcite standard. Lower intensity values were expected based on the sample packing method requested and the amount of alteration in the material deeper in the holes. Several clay separations were run using a new method outlined in this report. The methodology was very effective but I believe too time consuming for bulk amounts of clay separations.

Total Samples

• XRD: 382
• ICP: 0
• X-ray Diffractometer
• A full NIST 1976 QAQC was performed at the beginning of the expedition and did not show a need to adjust detector settings or apply a Zi Correction.

Quantitative xrd

The used method of quantitative XRD required several things: a set of standards with known and varying amounts of minerals to create a regression that normalizes samples and calculates weight percents of minerals, a homogenous sample mixture, and a randomly oriented sample mount. Samples were freeze dried and ground in the Mixer Mill to keep preparation methods consistent between the standards and the samples, and homogenize the sample as well as possible.

Issues

• While running the standards, many came out of the D4 with distinct cracks and powder that sprayed out onto the sample holder and inside of the D4. This was due to the clay content in the standards, the very humid environment, and the sample packing method. This coupling led standards to absorb moisture, expanding and contracting the material which when the sample started rotating caused some of the material to spin out. This was exacerbated by using their requested packing method of pressing down with a glass slide and not moving laterally over the sample. As a result samples were not packed as tightly and more prone to spinning out. To resolve this standards put into a vial with a large diameter and sat uncapped in open air. Exposing more surface area allowed the material to acclimate to the environment. Samples were also moved from a 1.8mm depth holder to a 2.0mm depth holder in hopes the deeper depth would secure the material better.
• The XRD lab currently does not have a way to accurately pack a randomly oriented powder mount. This was improvised by lightly tapping powder into sample holders and pressing straight down with a piece of glass. The glass could not be rolled around over the sample as it would increase preferred orientation. This method made it much more difficult to keep the material in line with the sample holder edge, occasionally with the sample becoming too full resulting in slightly shifted peak positions.
• There was a request for a randomly oriented powder mount with too little material to fill the 1mm depth sample holder. To get around this I took a cork ring from the alumina ceramic grinding vessels and cut it to wrap around inside a 1.8mm sample holder and filled powder inside of the ring. This worked out well. The cork was the same height as the sample holder so it did not affect the geometry of the X-Rays, cork is amorphous and doesn't produce a signal, and the x-rays should only be hitting the center of the sample so it preserved the true measuring area.
• Clay mount after coming out of the Muffle Furnace. Material is one solid piece and can slide off. Heated a Clay Separation Mount in Muffle Furnace. Too much material was added to the mount and the clay formed a solid layer that flaked off of the disk

Recommendations

Getting back loading sample holders would allow the lab to much more effectively perform quantitative XRD. A requisition was placed for a set of 10 steel back loading sample holders. This type of holder works by packing a sample into an empty ring and applying pressure to the back side of the material. This reduces orientation by not forcing mineral grains on the scanned surface to fit in next to each other allowing a truer representation of the amount of each mineral present.

Mixer Mill

Both Mixer Mills were used with 3 Alumina Ceramic Grinding vessels to prepare all samples. Only Alumina Ceramic was used over the Tungsten Carbide and Steel containers because ceramic has less risk of contamination. The vessels were easily stained by material and had to be cleaned by grinding silica sand in between each sample.

Issues

• Both Mixer Mills started screeching loudly indicating the grease had dried out on the exposed ball joint connected to the clamp retaining spring. The spring was taken apart and the ball joints were removed and re-greased. The manual indicates using a 'heavy duty automotive-type lithium grease'. I first tried the 'G-72 Red Lithium Complex Grease' spray. This grease was too thin and would wear off within hours leaving the spring and ball joints to start screeching again. Instead the 'Lubriplate' grease was used and there have been no issues since.
• Bent Mixer Mill SpringThere was a bend in the spring in the 8000M Mixer Mill. I was able to straighten it out with no problems but it may be wearing down. See the figure below.

• One alumina ceramic grinding vessel and one alumina ceramic grinding ball were chipped and ground down making them unusable. The ball was ground away while cleaning a container with silica and left us with three usable balls. All the balls started out at the same size and are now misshapen and irregularly sized.
• The grinding vessel developed a small chip and while processing a sample ground away. The sample material poured out into the Mill and was resampled at the same interval. Looking at the way the container was ground away I suspect the container lid was not lying completely flat against the holder clamp exacerbating the chip.

Chipped Alumina Ceramic Grinding Vessel. The top rim was significantly ground away.Chipped Alumina Ceramic Grinding Ball. Only half is left after the rest is ground away

• Several runs after regreasing the ball joint in the 8000M Mill the spring detached from the bearing causing the sample holder to swing freely and hit the motor. The Mill was turned off immediately and there was only cosmetic damage. Prior to this incident there was a gash over the label on the motor and is now deepened slightly. It appears the snap ring was not fully secured and with enough time let the ball joint slip out. When reassembling it is very important to ensure the whole area is clean and the snap ring lies flat inside the ball seat.

Mixer Mill after the spring detached itself from the ball joint. The sample holder hit and is now leaning against the motor.

• The fuse box located on the back of the Mixer Mill. Note the panel flips up and the black plastic box that holds the fuse. The fuse being held will be placed into the empty slot. The 8000M Mixer Mill blew a fuse. The fuse is located on the back of the Mill in the black box. With the aid of the ET both fuses were tested and only the right side blew out. Replacement fuses are in the top drawer of the X-Ray Prep Area in the Thin Section lab labeled 'Mixer Mill Spare Parts'

RECOMMENDATIONS

• With age and use Alumina Ceramic balls and vessels become more brittle making them more prone to breaks and fractures. I recommend keeping at least two spare balls on hand and one spare vessel on hand.
• Squeaking springs can also indicate that the spring will need to be replaced down the line. I recommend carrying a spare spring.

Freeze Dryer

All samples were first broken up into small pieces and then freeze dried a minimum of 12 hours before mixing. Samples at deeper depths required up to 18 hours to completely dry. The sample matrix got much finer and was more difficult to remove all the water even with samples being broken up first.

Haskris

The Haskris started leaking water from the D4 supply water handle at about 1L/day. We isolated the Haskris and determined the source of the leak was the valve. The old valve had rusted through and was replaced. The leakage damaged the insulation on the 'Ship Chill Water Out' line. New heavy duty insulation was put around this tube and extra pieces of insulation are on the top shelf of XRD lab above the safe. There have been no leaking issues since. XX is used for the handle so this issue will arise again.

Right: New valve installed on the D4 Supply Water. Joint is facing upward to reduce amount of sitting water corroding the joint

Clay Separations

Several clay separations were performed during long periods between coring. Separation of clay size fraction was performed in a different way than indicated by the manual. This method was very effective at getting a large amount of the >2um size fraction but was very time consuming and is only recommended when a few samples are requested. This method is not practical for bulk clay separations.
The method goes as follows:
Remove carbonates with acetic acid and dismembrate samples with a calgon solution. Take the dismembrated sample and pour into a beaker. In your sample beaker add 300ml of DI water. Hand stir the water and split the beaker contents between 10 different centrifuge tubes. Centrifuge samples for 4 minutes at 750RPM. This packs all the <2um material to bottom of the tube leaving in suspension the >2um material. Decant all the liquid from your centrifuge tubes into a beaker – this contains the >2um size fraction. Add 15 ml of DI water back into each centrifuge tube and centrifuge for 4 minutes at 750RPM to pick up any remaining >2um size fraction that may have settled to the bottom. Decant this liquid into the same beaker containing all the suspended fraction. The beaker is now full of >2um material. The contents of the beaker are then split into 10 new centrifuge tubes and the sample is spun for 60 minutes at 3000 RPM packing all of the >2um material into bottom leaving clear water and an extremely small size fraction suspended. Decant the water into sink. Take the 2um material at the bottom of each centrifuge tube and add into one 50ml beaker. Once all the clay is in add a small amount of DI water was to bring the total volume up to 20ml. Dismembrate the beaker for one minute to suspend the concentrated amount of the >2um size fraction material. Then make the mount as usual with an eyedropper onto a zero background Si disk.
If too much material is put on a disk during a clay separation it is possible for the whole sample to peel after it has dried, especially in the instance of heating in the muffle furnace.

Maintenance

• Freeze Dryer Vacuum Pump
• The oil for the Freeze Dryer Vacuum pump was replaced on 28 September 2016.
• Platinum Crucible
• 10 recast Platinum Crucibles were received at the end of X362T. These were acid washed and put away in the safe.

Softrware Updates

• DQuant software was installed and set up on all computers with XRD Software with help from the MCS. The software was previously on the computers but the dongles were unable to communicate with the newer versions of Windows. DQuant is a part of the Diffrac.Suite software package and designed for quantitative XRD Analysis.
• A macro was made to help automate processing sample data. When viewing appended areas in 'Area Column View' on EVA, scientists can copy the data directly out and paste into this macro. It has been designed to pull out certain values for multiple areas within the same sample. The macro will parse out sample IDs following the LORE Report format, display peak intensities, calculate weight percent, and pull associated depths from a separate depths reference sheet updated by the technician. This was deployed for Site U1481A and did not encounter any bugs. The macro has been made to be general so depending on the specific data wanted by the scientist only a few minor tweaks will need to be made. This macro is saved as 'X362 Quantitative Data Processing' in IODPShare > XRD > Sample Codes

THIN SECTION LAB

SUZAN BOEHM

Summary

Friable [frahy-uh-buh l] adjective ....easily crumbled or reduced to powder; crumbly: friable rock.
42 thin section requests. Mostly sandstone, mudstone, laminated clays, with few basalt and igneous billets. The clays and mudstones were not very successful. Trials with thinning out the epoxy with acetone and using a glycol slurry instead of water were mildly helpful when working with these very soft, friable, and soluble materials. Grinding and polishing by hand on a glass plate was more helpful and less damaging to the samples.

LP-50

I replaced the nut on the roller arm so that there is higher clearance from the surface of the lapping plate making initial adjustment of the height easier and less likely to come in contact with the plate since on the ship we have to actually use the roller arms upside down from their factory recommended orientation.
Plate monitor and both short and long cables worked great, never any need for adjustments and always well within our flatness range. I only used one jig for everything and adjusted it back and forth between slide frosting and lapping billets, this worked well and let me finely tune the surface height as needed. Good idea to double check the surface height of the jig every time as it changes slightly with each use.
Abrasive Drum: One of the rollers for the abrasive drum locked up during use and caused a terrible squeaking/grinding sound. Set screws just needed to be loosened and readjusted so that the rollers move freely. I washed out the drum and refilled it with RO water and grit and then when in use the slurry would just drip out at a super high rate and I could not control it by adjusting the white valve. It was because the "anti-backlash nut" (the metal circle with 3 holes inside the valve) wash pushed all the way in and needed to be closer to the outer rim of the valve adjustment cap. I used long needle nose pliers to grab the holes and turn it until it was back in place. Once the anti-backlash nut was back in place the three pins with springs on them could stick into the holes as intended.
I also repaired the broken valve on the second large drum. One of the pins was bent and preventing the valve cap from being screwed into place. I used a very sophisticated un-bender (hammer + carefully applied brute force) to straighten out the pin. Both valves and drums are functional and the drip rate adjustable.
The TS Cookbook suggests picking up the drum and shaking it to suspend all the grit if it has settled before using it on the lapping plate. The manufacturer's manual however clearly advises against this as it may clog or damage the valve. I found the slurry mixed up just fine if I turned on the abrasive drum override and let it spin for a few minutes before using it, avoiding having to pick it up and shake it all the time. I think this way is much nicer on my back and the drum.
The Edwards vacuum pump stopped working because the black tubing had cracked. I cut off the cracked section and reattached the tubing to the pump and it is working fine again. However, eventually I think the entirety of the black tubing will need to be replaced. Keep an eye on the pieces that are near the moisture chamber, they look like they will be next to break.

Petrothin

No problems. Always achieved an adequate vacuum when cutting billets. I had to switch over the vacuum to use for impregnating billets and the six chambered bell jar stand multiple times and this was not creating a vacuum. Copious amounts of clear 111 lubricant/sealant needs to be applied around the rim of each jar and when they are pressed down a vacuum can be achieved.

WG-2 Polisher

Some of the pegs seem to be sticking and not applying adequate pressure to the billets even when using multiple weights. I never had to use all six at the same time. They still spin when in use but I feel like not as freely as in the past.
In the next shipment the lab should be getting a replacement piston arm. Hopefully the current one can be repaired once it is removed so that we can have a spare.

Samples and methods

The current method of etching the sample ID with a diamond tipped scribe onto the slide is very difficult to read and does not image well so I started typing out labels using the Brady label maker instead. They !worddava8d24dec7334c85fbcb8dc9b5c1ea4a9.png|height=140,width=210!can be seen on both standard and polarized images and way easier to read with the naked eye. I still scribe on the slide itself to that there is a permanent ID incase the label falls off.
I use the same labeling format as when using the label makers for hardrock curation. I added the TS request number and also remember to add an arrow on the bottom line in the appropriate direction if the sample is oriented. I tried to bond the billets to the slide so that enough space was on the side to apply the label. This started out because the scientists were placing oil with a coverslip over the finished thin sections to get a clearer image. Once the oil is applied you can no longer read the scribe so the labels became necessary. If it is not possible to have enough space for the small square label it can be cut in half between lines 2 and 3 and both halves placed sideways on the slide.
Working with the laminated clays was the most difficult. Even after being submerged in epoxy and placed under vacuum multiple times the billet never seemed to get impregnated properly. It is possible that the clay particles just do not have any pore space between them to allow the epoxy to absorb. Methods that I researched and are now on the thin section lab PC all used different types of epoxy, allowed for multiple days (even weeks!) of soaking in solution, or other techniques that would just not be feasible on the ship like using an alternating vacuum and high pressure chamber. On the suggestion of a scientist I mixed a small amount of acetone into the epoxy to thin it out and hopefully absorb better.
The method that I got the best, but still not very good, results with was as follows: Thoroughly mix epoxy parts A and B. Add a few ml of acetone and mix well again. Cover just the surface of the sample with epoxy and vacuum, release, and repeat multiple times. Pour a little bit of epoxy in the bottom of a plastic mold, do not cover the sample. Lay sample into the mold epoxy side down, this is supposed to let the air bubbles out the top while soaking in epoxy from the bottom and using capillary action. Vacuum, release, repeat multiple times again. Use a pick to slide the billet around and get any air bubbles off the bottom surface as that will become the bonded surface. Cover the rest of the billet in epoxy if you think it is necessary to preserve the sample, this will also leave more opportunity to make additional thin sections out of one billet if necessary. Once the sample hardens and cures sanding down the surface to bond to the slide was very tricky. The margin of error (between sanding enough of the epoxy off but not exposing un-epoxied sample) is incredibly thin since the epoxy cannot seep in well beyond the surface.
Instead of using the normal water based slurry it is best to use glycol when working with these muddy, clayey samples. In the second large abrasive drum I combined glycol with 600 grit powder in the same proportions as the cookbook describes. Also when using the petro thin do not turn on the water. Instead use the spray bottle with glycol to constantly wet the sample and blade. Having a second person do the spraying helps but it still creates a lot more vapor and dust than using water so definitely use a face mask. The LP-50 was usually too harsh on any of these samples and would end up with most of the sample being ground away almost immediately. I ended up using the grinding plate (on the petro thin) to make the sample thinner at first, and followed that up with hand grinding on a glass plate.
!worddavf931bff84315765240985915adf074b0.png|height=135,width=202!Hideki Mukoyoshi on the science party formerly sailed as a thin section technician on the Chikyu and showed me how to grind samples by hand. Use a large glass plate (found under the forward sink) and the same 600 grit that goes into the abrasive drum. Other finer grits are in the blue cabinet. Sprinkle a small pile of grit onto the plate and just use your hand to add some water to make a slurry. Put the slide with the sample side down and apply pressure with your fingers while moving the slide back and forth. Add more grit, or more water to make the slide move easily. This is better than the lapping wheel because the thickness of the sample can be checked very frequently with ease and is far less aggressive. After grinding by hand with 600 grit the samples would usually be placed on the WG-2 polisher for a final polish or to get it to a useable thickness. Even still, the material chosen is just not very workable for thin sections in our lab and stripes of the billets would wear away super quickly and leave other very thick stripes in between. A couple examples of this are below. I redid these samples multiple times with limited improvements.
Hideki also preferred not to frost the slides that he worked with when grinding by hand. The billets were bonded directly to the slide after cleaning with alcohol. He says that this produces a clearer view of the minerals and cuts out the entire process of having to frost slides first. The 1000 grit can be used for a polish at the end or the WG-2 with diamond grit. He only did this with basalt samples so I do not know how effective it would be with softer material.
Mineral crustwood !worddava52893ef609be57d26de94791b5491c2.png|height=135,width=182!A thin section request was made for pieces of wood recovered from one of the cores. I used a plastic mold, spread a thin layer of epoxy inside and then placed the pieces in the desired orientation and left it that way until the epoxy was just starting to firm up. Then I poured more epoxy over the top to keep everything together. I used the petro-thin as normal and then continued to grind down the sample by hand so as to go easy on the organic matter. This worked surprisingly well. Another unusual request was a thin section of a sliver of mineral crust. I stood this up on its side in a small mold and cured it that way and a thin section was successfully made of the slice.
Instead of sand paper from the UT shop I made use of the circular grit pads and used the Beuhler grinding wheel to flatten and smooth billets. There is a magnetic disc for each grade of grit so it can be reused when the paper needs to be changed. Check the small sediment trap under the sink where the grinding wheel is. It was always fine but I preferred to check it often just to make sure it was adequate and to confirm that we do not need a large sediment trap under that sink.

Miscellaneous

The extraneous sediment trap underneath the forward sink was finally removed and the pvc was sealed off. The sediment trap with appropriate tubing is stored in the UT Shop with the other spares.
Bulb replaced in microscope for reflected light. The spare old microscope is stored in the most forward cabinet in the paleo microscope lab.
Beth and I used clear sealant to re-caulk portions of the super saw splitting table that were leaking through and causing large puddles on the floor. Since the sealant was applied we have not noticed any leaking.
Eight containers of very long ago expired part A epoxy needs to be disposed of during port call. The MSDS is attached to the containers.

UNDERWAY GEOPHYSICS & FANTAIL REPORT

KEITH DUPRIS

Summary (Underway Geophysics Lab)

Navigational data (GPS) were logged by the WinFrog software (on WinFrog1 computer) during all transits and at each site. The magnetometer was deployed during the first transit (L1T) between Colombo and the first site (U1480) and second time on a short transect from site U1481 to Singapore. Bathymetric data were collected during five transits. All scheduled VSP where cancelled due to time constraints. The WinFrog2 computer was sluggish, crashed while recording bathymetry and frequently disconnected from the ship's network. A replacement machine with the same setup was installed prior to our transit into Singapore.

Transits

Five transits occurred and two sites (U1480-81) were cored during Expedition 362. The first transit (L1T) was from Colombo to Site U1480. The second transit was from U1480 to U1481. The third transit was from U1481 to Singapore for repairs to drilling equipment. The fourth transit was from Singapore back to Site U1481. The final (fifth) transit was from U1481 to Singapore, and the end of the expedition. The transits are listed below and include a sub-list of data collected^*:

• Colombo, Sri Lanka to U1480 (L1T ≈ 842 nm)
  • Magnetometer
  • Bathymetry
• U1480 to U1481 (L2T ≈ 19 nm)
  • Bathymetry
• U1481 to Singapore (L3T ≈ 996 nm)
  • Bathymetry
• Singapore to U1481 (L4T ≈ 989 nm)
  • Bathymetry
• U1481 to Singapore (L5T ≈ xxx nm)
  • Magnetometer
  • Bathymetry

(^* GPS data were collected during the entire expedition.)

Navigation Data and Winfrog software

The aft/forward Trimble GPSs were used to log GPS data every sixty seconds when underway and at site locations. Data were recorded to three separate files. These data files included latitude, longitude, time (hours, minutes and seconds only) and the depth estimates from the Bathy2010 when this was logging. The Fugro Pelagos Winfrog software routes the data from the GPS, Bathy2010, Magnetometer (and others: e.g. Gyro compass, etc) when recording and writes them to .dat text files. The three files were concatenated into one final file.
Site-fixes were performed at each site/hole using at least one hour of 1-minute samples after entering the hole.
The latitude and longitude recorded from the GPS were plotted in Figure 1.

Figure 10 Expedition 362 transits between Colombo, Sites U1480, U1481 and Singapore.

Bathymetry Data

The Bathy2010 instrument and software package was used to estimate and record depths on four transits (see list above.) Table 1 is a log sheet of basic information from the bathymetry data recordings. It includes filenames of the logged data, start and stop times (GMT), number of samples, start and stop Latitude and Longitude and comments. The shading indicates each transit. For example, the first three rows are shaded to indicate that these three files are associated with L1T. The comments help explain why there were multiple files for one transit (e.g. computer or software crash) and other information.

Table 1: Bathymetry (Bathy2010) file logsheet. The grey shading indicates the grouping of files for each transit

Bathy2010 SEG-Y Format

The files listed in Table 1 are the raw Bathy2010 proprietary format (.odc.) These were converted to SEG-Y, a common binary format used in the industry. These were loaded and plotted in MATLAB and Petrel. The SEG-Y files are the raw data from the instrument as opposed to the frequency-filtered data that the Bathy2010 software calculates "on-the-fly" while measuring to estimate the seafloor.

Recorded Depths

The estimated depths from the Bathy2010 were exported from .odc to .xlsx format and also recorded as a column in the navigation .dat files as a separate listed parameter. The .xlsx format is not that useful because there is no time-stamp or navigation data associated with it. The depths recorded (via Winfrog software) in the navigation files are more useful because they include a time-stamp (hour, minute and second only) plus navigation (latitude and longitude.)

Magnetometer Data

The SeaSPY magnetomer (aka. Maggie) was deployed on 10-August-2016 at 02:01:51 GMT while transiting to the first site. It recorded pressure and magnetic field every 3 seconds. The Maggie was towed along a second transit during the final leg from U1481 to Singapore. The data were logged to files. Figure 2 shows the Maggie data collection tracks. The first track is the longer red-line. The second track is the shorter yellow line. The second track is exaggerated and is mostly a track over the two sites.

Some other notes are listed below, and the raw data from the first transect are plotted in Figure 3. There was no time to plot or review the second tracks data as it was collected it the day the tech. report was due.

Hardware/Software issues

The Underway lab instruments appeared to perform well on Expedition 362. However, the WinFrog2 computer frequently seemed sluggish and often lost its connection to the ships network. A new Winfrog2 computer was built and installed to replace the WinFrog2 machine that started this Expedition. The new machine collected the final two bathymetry files (PDR and final transit.) It works. The Bathy2010 software lost the latitude and longitude signal frequently on the first WinFrog2 machine. This affects the .odc files.

JRData Server and JRNav-Google EartH

A new version of JRData Server has been released. Fixed an issue with parsing the ship's speed over ground from the WinFrog data. In some cases, it would set the value to zero which caused JRNav-Google Earth way point tracking window to indicate that the ship was at destination or stationary.
A new version of JRNav-Google Earth has been released which connects very fast (instead of the minute wait) to the JRData Server.

• Note: Tools 1858002C and 1858023 have been calibrated and are in the Singapore shipment.
• Note: Screws holding on the battery for tool 1859005C were too long and jammed the tool during insertion into the cutting shoe. These were filed down for a good fit.
• The shoes were cleaned and prepped. We used tools 5 and 7 for Exp 362. Ran several deck tests on tools 5 and 7. Tool 5 failed during a temperature run, later investigation found that the battery had discharged down to 2.6 volts. The battery was replaced. Tool 5 was used on later runs successfully.
• APCT-3 Tool 5 was run in site 1480E Cores 06, 08 and 12. Did not recover data on core 08. Possibly a battery issue.
• APCT-3 Tool 5 was run in site 1480F Cores 04, 06, 13 and 22. All good runs.
• APCT-3 Tool 5 was run in site 1480H Cores 04, 07, 10 and 17. All good runs.
• APCT-3 Tool 6 was run in site 1480H Core 12. Run was good.

UPS power supplies

• UPS power supply N1896 batteries failed, the batteries were replaced.
• UPS power supply N3663 batteries leaked inside the unit, we decided to decommission the unit.

ET workshop

• Replaced the motor on "Shop Vac" IODP 001.
• Replaced serviceable parts on the workshop Bio Fit chair.
• SNMP-V6 UPS manager software has been installed on the ET Shop PC, Thermcon PC and the LO's computer to monitor the Minuteman UPS's. We installed a SNMP-V6 SNMP Lan card in UPS RF 52907 as a test to communicate with the computers.
• Note: A. UPS Password is "Device Name-device" B. Password is: "upspower"
• On Internet Explorer-Top Bar: 165.91.72.50 or Minuteman-Thermcon
• The grinder with IODP number 096 was decommissioned. (This was an old 240Volt grinder)
• We manufactured several jigs for the Ice Field and Flex-It tool testing.

BAT TRACK

• The SHIL LED and M-drive power supplies and light drivers were installed.

Core Lab

• The second Emergency Stop switch on the Cryomag (SRM) was permanently installed.
• We changed out the Ocean Optics bulb on the SHMSL track on Aug 7 and Sept 10 2016.
• Cleaned the Excelsys Exgen power supplies on the SHIL and the SMSL tracks.
• The P-Wave exlar system was pulling cores to one side of the track. The exlar locked up and had to be manually opened. We added Kopr Kote to the moving parts in the hopes that it would decrease any friction in the system. We then notice quite a bit of play on the copper bearings and decided to re build the P-Wave hardware. After the rebuild everything seemed to be working smoothly.
• The Cryomag "SRM" M-drive positioning motor started slipping. We thought that the motor coupling to the shaft was the problem, so a small flat spot was filed onto the shaft and a set screw drilled and tapped for the sprocket. Everything was working fine but later there was a new noise from the drive system. We attempted to lubricate the bearings with Dry-Slide, it continued to make a noise. We then found that the motor to shaft coupling was rubbing on the motor face. We added four washers to the mounting plate of the motor to give the coupling more space by moving it out slightly and then re aligning the motor and shaft coupling.

SRM notes:

• The SRM had various problems this expedition.
• At first there were a scraping sound when the track was moving in one direction only, into the SRM. Then we started noticing a jerking motion on the boat at certain track speeds and heavy core weight.
• The first issue was identified as the coupling between the motor and the shaft slipping. The second problem seemed to be the port side shaft bearing, there was a third problem the motor shaft coupling being squeezed.

JR-6 spinner notes:

• JR-6 Spinner Magnetometer shaft started grinding as it moved up and down. The shaft was cleaned and just a small amount of lubrication added to the slide bar screw.

VELOCITY-GANTRY notes:

• We had a very weak signal on the Gantry track transducers, the Olympus Ultrasonic pre amplifier failed. This is the pre amp for the large transducers. During troubleshooting we found the Acopian model 16E08 regulated AC to DC power module inside the amplifier unit had failed. We rigged a 15Vdc wall wart power supply as a temporary workaround and a new power module has been ordered. But Mr. Mills decided to use a spare Olympus transmitter/receiver unit, just the signal amplifier part, it is set to +24dB.

Paleo Lab notes:

• The Heiser light source started to blink intermittently; we cleared this by replacing the bulb.
• We replaced the elements in two heat sealers.

Core Spitting room:

• The forward most saw tray was rubbing against the frame. We smoothed the right side (facing the saw) of the tray.
• We had an intermittent fault on one of the door pads that caused the doors to open and close on their own. We found a bare wire at the connector and two wires shorting near the pad, this was repaired.
• The same sliding doors started opening again on its own, this time we found the door limit switch was not making contact as the doors closed. By just bending the limit switch arm we seemed to fix the problem.
• The techs reported that the super saw would trip by what seemed to be an over current situation when they tried to move it. We found that the saw storage slide bars were very sticky, we cleaned the stainless steel bars and the problem seemed too clear. We also added a small amount of Kopr Kote for lubrication.
• The center saw started making a grinding noise, almost like something was scraping on the fan belt cover. We found that the drive pulley to the belt drive had worked itself loose. The pulley was re aligned and the set screw tightened.

LN₂ Gen notes:

• The LN₂ Gen ran twice this expedition without any problems.

-86Freezer on F deck:

• Cleaned out the door seals and de frosted the door seals.

Chem Lab:

• Changed out the oil in the 220V vacuum pump for the freeze dryer on Aug 07.
• The chem lab technicians requested three custom sample holders.
• Center Carver Press (Bill) started to make mechanical noises and would not pump completely up, if or when the pump reached the sample it would not hold pressure. We fixed this problem by bleeding the hydraulic system and adding half a bottle of Carver Hydraulic fluid to it.

Thin section Lab:

• Replaced a blown fuse in the mixer mill.

Upper Tween stores:

• The Makita Mitre saw safety shield jammed intermittently, the cover needed some alignment.
• The band saw blade was found to be loose, we did a setup check on the unit.
• The belt sander sanding belt was found damaged and replaced.

Underway:

• The "Maggie" was successfully deployed and retrieved, using a battery drill on the worm gear.

Gym notes:

• Replaced batteries in the new and the old display units of the stationary bicycles.
• Cleaned the large Cybex treadmill. During routine servicing we found structural damage to all four of the plastic covers. We used 5-min epoxy to re-enforce several areas of the covers so that they could be re attach properly. Replacements for all the covers has been ordered.

One of the main front bolts on the frame had sheared off, the bolt was replaced.

Manufactured a holder for the speed bag pump and installed it in the Gym.

Movie room:

• Changed out all the movie room remote controller batteries and cleaned the UPS. UPS # RF 52978.

Fantail:

• The Gun line winch (Starboard) was greased, cleaned and exercised. The Fantail Crane was greased, Dry Slide applied to the cable and exercised. The boom extensions will not extend out. The Boom will move up but not down. The reel goes out but not in. The seismic winch (Port) was cleaned, greased, had Dry Slide applied to the slide bars and exercised. The seismic winch continues to have problems tracking. We continue to use a temporary workaround to deploy and retrieve the Magnetometer. Assisted in the preparation of the seismic air gun cluster. Cleaned and re stowed at the end of the expedition.

Misc:

• Cleaned the filters in all of the vacuum units.

SHIPBOARD SAMPLING

CARB, MAD, NANNO, PMAG, RADS, and XRD samples were routinely taken from the working halves.

Residues

The residue distribution is as follows:

• The geochemists included the types and volumes of residues they would be requesting in their sample request. Geochemistry residues were then divided as the samples were processed.
• All residues, with the exception of geochemistry residues, were reassigned to each scientist's request code and number.
• Biostrat Slides: Jan Backman (39482IODP), Wenhuang Chen (39507IODP), Sarah Kachovich (39446IODP), and Freya Mitchison (39786IODP) requested all slides they made from the working halves and core catchers.

• Smear Slides: For core description to the KCC. [Loan requests from Steffen Kutterolf (39464IODP), Freya Mitchison (39786IODP) and Paola Vannucchi (41941IODP) under "Action Items".]

Thin Sections

A total of 41 thin sections were made during the expedition by Susan Boehm. They will be shipped back to the Kochi Core Center with the other residues.

SAMPLE REQUEST NUMBERS AND CODES

Below is a list of shipboard scientists, their sample request numbers, and their assigned sample request codes:

Below is a list of shore-based scientists, their sample request numbers, and their assigned sample request codes:

PROBLEMS ENCOUNTERED

Core Expansion: U1481 cores started to expand after they were brought in from the catwalk. We decided to tape the bottom end caps with electrical tape on the catwalk and then sonic weld the endcaps on after sampling and describing had been done on both section halves. In the case of a considerable amount of expansion of some of the sections, liner extender was applied with acetone. Curated length for sections that had expended more than 2 cm were changed in SampleMaster
Crushed and Shattered Liner: Some of the U1480 core liners were crushed or shattered when they were received on the catwalk. We accommodated for this by acetone-ing liner patch to reinforce some of the sections.

COMPUTER SOFTWARE

Request Code Manager: A new sample request code manager was implemented during Week 6 allowing me to assign sample code to sample request numbers without the developers help.

ACTION ITEMS

Sedimentology Smear Slide Loan Requests: There are two requests to borrow smear slide post cruise. Steffen Kutterolf (39464IODP) and Paola Vannucchi (41941IODP) have requested to borrow smear slides for a period of up to one year. These smear slides will be sent to the KCC and will need to be sent to the requester for a period of one year upon their arrival. The Expedition 362 SAC has approved this request. The requesters contact information is as follows:

MISCELLANEOUS

Auther: The curator was given all privileges for all of IODP's applications and the ability to grant these privileges to others.
Play Core: A couple of mudline cores were greater than 9.5 meters. The drillers eventually realized there was a calculation error in their drill pipe tally. Since the mudline was missed, we did not know where the sediment/water interface was or the depth of the seafloor. These cores were entered normally and were ran through the whole round tracks. U1480A-1H, U1480B-1H, and U1480C-1H were split and sampled as normal. U1480D-1H was donated by the Expedition 362 SAC to the JR for testing and training. It will not be used in future expedition science.

PUBLICATIONS REPORT

JEAN WULSON

Summary

• My duties included collection of publication materials from the scientists and generating the visual core descriptions (VCDs). I generated VCDs for two sites and eight holes, core recovery figures for each hole/site, and figures for the Methods chapter.
• I distributed/collected shore passes, passports, and crew declaration forms from the scientists and technicians for port call activities. I also kept track of seagoing personnel using the check in/check out spreadsheet for port call.
• Other expedition related administrative duties.
• When I had free time, I assisted on the catwalk.

Equipment & Software Performance Summary

• Software used: Strater 4, Acrobat, Illustrator CS6, Excel, Word, Groupwise, FontCreator. Any issues with the software and the Yeop PC computer were addressed and corrected on the ship.

Database, entries, and data upload or downloaD

• L2E was used to export depth, section, core scale, title, core images, samples, some analysis data, and core composites photos. I experienced no problems with the performance of the L2E software.
• DESC export was used for all core descriptive data. I experienced four problems with the use of DESC:

1. When doing an all-tabs download, the data from different tabs would intermingle and appear on different tabs. This was corrected in DescLogik 16.1.0.3.
2. Bottom depth of U1480G was not updating after a depth recalculation of the hole. Algie and Tim manually changed the depth, but this problem is still unresolved (as far as I know).
3. After version update Desclogik v. 16.1.0.5, DESC did not download top and bottom depths for cores/sections/intervals. This was corrected with Desclogik v. 16.1.0.6.
4. After version update Desclogik v. 16.1.0.6, the classifications were visible where they had previously not been visible. Also, the scientists were not able to use the auto complete function of data entry. These were corrected in Desclogik v. 16.1.0.7.

• Lims Reports/LORE exports was used for downloading all track data for plotting in Strater in order to utilize the trim data feature. This feature did not work on NGR until Algie fixed it with software update limsM Web Services version 1.2. Otherwise, the database worked fine.
• Limspeak – no problems with the use of this program.
• Virtual Photo Table – glitch in programming made it stop working randomly. Per Tim Blaisdell: The program has a timer set to fire once per second. In there, it says "does the time since the last processing equal the specified interval?" The problem with that is that the time might fire at some second 1 + 99 ms, and then by chance not fire again until 3 + 01 ms. The time between firings is only 2 ms over 1 second, but a second has been skipped. Thus, the fix was simply to use ">=" rather than "==" in the comparison of the interval. Corrected with software update VirtualPhotoTable v. 6.2.0.1.

Volume Materials

• Chapters were collected as they were finished and I kept track of all material using the tracking logs for text, tables, and figures.
• In the beginning, I updated the VCDs twice per day and provided the scientists with a PDF with comments indicating areas of concern. When the recovery rate slowed down, I produced VCDs once per day.
• Minor changes to the description/interpretation process occurred multiple times throughout the expedition requiring new downloads and replotting of VCD data multiple times. In addition, various depth issues occurred that required rebuilding the depths and, in turn, required replotting the data.

General Duties Performed

• Exported data using L2E, DESClogik, and Lims Reports; reviewed data for accuracy and ; plotted data using Strater software version 4; produced PDFs of the VCDs, and recovery plots; and distributed PDFs to the scientists for review.
• Worked with the scientists to ensure accurate data display in the VCDs. Corrected/modified VCDs, Strater schemes, templates, and Methods legend figure as needed.
• Collected, organized, and tracked all publication volume materials including text, figures, and tables in hard copy and electronic files.
• Assisted scientists with figure creation and in the use of the Adobe Illustrator software.
• Attended science cross-over meetings as needed.
• Provided administrative support to scientists and technical staff as needed, including providing supplies and assisting with travel arrangements.
• Distributed and collected necessary expedition paperwork - IODP communication policy, photo image release, manuscript and copyright forms, cabin repairs, personal safety equipment, and shipboard network access.
• Worked with the Radio Operator to ensure the science party and technical staff had appropriate documents for departure from Colombo and arrival in Singapore.
• Kept track of seagoing personnel using the check in/check out spreadsheet for port call.
• Arranged movie nights for technicians on 6 to 6 day shift
• Planned and executed the Kite Flying Contest and T-shirt logo contest.
• Arranged birthday celebrations for 5 scientists and technicians.
• Communicated with shore staff regularly to provide updates.
• Restocked Publication supply cabinet as needed, and provide science party with supplies per request.
• Updated IODP book library spreadsheet with actual book location for books moved from the User room to the Conference room. Re-stickered the books with correction location.

DEVELOPER'S REPORT

ALGIE MORGAN & TIMOTHY BLAISDELL

Overview

This document highlights changes to the JOIDES Resolution laboratory data management environment during Expedition 362.
Selected issues are highlighted, but not reviewed in exhaustive detail. In general, see the ship activity log and Pending pages of various products on the developer site for additional detail: https://sites.google.com/a/scientific-ocean-drilling.org/developer-page. The title of each product section is a link to the release notes for that product on the development Google Site.
The web service redesign project completed on 362T, just prior to the beginning of Expedition 362. TAS and the application developers conducted an extensive project to test all of the applications and track systems during the transit. They did a very good job of finding and correcting all of the major problems during the test phase. As expected, however, there were a significant number of minor bugs that remained to be detected and fixed; the first three weeks of Expedition 362 were devoted to the process of fixing issues reported by techs and scientists. As of the writing of this report there have been no significant problems reported and we have high confidence that the new web services are performing to their designed specifications.

WORK IN PROGRESS

During 362 the developers actively participated in development of:

• Complete the refactor of IMS system; add motion and instrument plug-ins for the Superconducting Rock Magnetometer (SRM), fix bugs in Sample Information dialog, and other optimizations.
• Completed a new Request Code Manager program for use by curatorial staff.

WORK COMPLETED

Curation and Core Handling

SampleMaster

• Changed. Operating at release 12.2.0.1
• Modified to use new web services (this modification made on Expedition 362T).
• Fixed a defect: exception when the user changed the core type on the Edit tab.
• Fixed a defect: request code list not populated.
• Made changes to allow SampleMaster to run and present a usable UI when run on a machine where the OS font size setting has been set to a non-default setting.
• Fixed a defect: when the user used the right-click -> Delete -> Entire Row option to clear a row on the Enter tab, the internal "dirty" flags SampleMaster uses to determine what needs to be uploaded would get out of sync. This resulted in rows that had changes (or new samples) in them not being uploaded, and sometimes caused errors to show (red color) on fields that had nothing wrong with them.
• Changed Parameter Search as follows:
  • Sort order now works.
  • If no sort order specified, samples appear in depth order.
  • Ability to search for a range of cores.
  • Minor fixes to other parameters that didn't work right.
  • Horizontal scroll bar no longer appears underneath the hierarchy search lists.
• Fixed several places where it was omitting "status = 'D'" in filters to samples and tests.
• Fixed an issue related to samples getting their parentage incorrectly assigned upon upload (manual entry of samples).
• Fixed an issue related to samples getting their parentage incorrectly assigned when data was pasted into SampleMaster from a spreadsheet or CSV file. NOTE: This change is in SampleMaster version 12.2.0.2, which has not been deployed on ship, but is checked in and ready to be deployed at AD\DEPLOY\product\clickonce\samplemaster.

Geology

DESCLogik

• Changed. Operating with release 16.1.0.7.
• Modified to use new web services (this modification made on Expedition 362T)
• Fixed a defect: non-admin users were not able to recover autosaves.
• Fixed a defect: after recovering from an autosave, it was not possible to upload data.
• Fixed a defect: if a template had two tabs with columns defined the identically (i.e. drawing from the same qualified parameter/value list), then data for that column from both tabs would appear on both tabs when downloading. This caused data to appear differently depending on whether you did an all-tabs or a single-tab download, since the all-tabs download would retrieve data for both tabs.
• Fixed a defect: the "View data properties" feature (right-click on a cell) was broken.
• Added a new formula function "concat", which will concatenate a list of columns (along with optional string literal values) to populate a column. This is used in some of the 362 templates (e.g. 362_macro -> sediment -> Bottom contact or geometry+definition)
• Fixed a defect: If a tab contained more than one formula column, only the first one was evaluated.
• Made changes that greatly increased the speed with which Desclogik loads templates and downloads data (16 sec. vs. 44 sec. for loading a template, 3 min. vs. 9 min. for downloading all data on a big hole).
• Note: A few minor issues showed up after the above optimizations were added. Subsequent versions were mainly clean up. As of now, all known issues of this type are resolved.

Virtual core composite GENERATION (aka Virtual Photo Table)

• Changed. Operating with release 6.2.0.1.
• Modified to use new web services (this modification made on Expedition 362T)
• Fixed a defect: there's a timer in VPT that fires once a second. In its event handler, it was checking for elapsed time == specified interval. Every once in a while, the timer would fire in such a way that a second was skipped and when the skipped second happened to be the one in which the comparison would have been satisfied, then VPT would appear to stop working altogether, since the equality comparison could never again be satisfied. This was fixed by replacing "==" with ">=".

Stratigraphic Correlation

[ SCORS Data File Download

• https://sites.google.com/a/scientific-ocean-drilling.org/developer-page/applications/java/jnlp/scors-downloader]Changed. Operating with release 12.

  • Modified to use new web services (this modification made on Expedition 362T)
  • Made slight modification to fix header so Correlator 2.1RC2 will import file.

SCORS Splice File Fixer

• No Change. Operating with release 14 since Exp. 362T.
• Application was modified to work with the new web services on 362T, no modifications were required on Exp. 362.

Scors aFFINE/SPLICE uPLOADER

• No Change. Operating with release 3.
  • Application was modified to work with the new web services on 362T, no modifications were required on Exp. 362.

Microscopy and Imaging

360 ImagE Composite Processor

• No change. Operating with release 4 since Exp. 362T.
  • Application was modified to work with the new web services on 362T, no modifications were required on Exp. 362.

ImageGRABBER

• Modified to use new web services as of Exp. 362T.
• Fairly major modifications were made to this application during 362. Changes include the following:
  • The user can select multiple holes to download images for.
  • Several analyses are now supported, rather than only LSIMG. The user can select among the following:

LSIMG
CLOSEUP
COREPHOTO
MICROIMG
SEM
TSIMAGE
WRLS
WRLSC

• • As analyses are selected, a third listbox is updated with the available images for each analysis. As before, LSIMG includes "consumer", "cropped" and "original". Most analyses include an original (tif) and consumer (jpg). Some include only one.
  • The internal workings of the downloader have changed so that it uses TestWorkingSetGet followed by multiple calls to TestsGet to get the samples, tests and results it needs. Also, "binning" is used to ensure that the URL is not too long, since there might be several thousands of tests to retrieve, depending on what hole(s) and analysis(es) they picked.

Geophysics-TRACKS, IMS Applications

• IMS 9.2 was deployed ca. 17 September to all tracks systems except for the NGR.
• A new SRM DAQ and INST modules have been added to IMS. This software replaces both section and discrete version of the previous application. In addition this release includes replacements for all of the other SRM utilities such as DAFI, U-Turn, etc
• MagSpy is a new IMS LabVIEW application that works with the SRM Instrument modules that provides a number of real-time features for the paleomagnetics lab. In its current release it must run on the PC that controls the SRM. In its next release it will run on any network connected PC. It provides the following functionalities:
  • Plots for Zijdveld, Equal Area and Demagnetization for a sequence of demag steps
  • Printout for the above plots
  • XYZ moment and Intensity, Inclination, and Declination graphs
  • Real-time ship's head indicator.

Data is provided by sharing global variables, which in the next release will network shared variables. The code is part of the I_PI_SRM instrument library.

IMS Changes

Version upgrades are deployed when a significant number of changes have been made or changes that creates an incompatibility between the releases. In this case, both apply. The SRM projected forced a number of changes and additions to the IMS_Common toolbox libraries. In particular, changes to "FILE INI Writer.vi" (writes and reads various ini files used by the IMS's DAQ, INST and MOTION modules) resulted in a file format change, therefore; pre-9.2 configuration files can no longer be read. The previous version of this vi relied on Open_G libraries which were unable to read variant data written as part of an array of cluster. Checking the LabVIEW forums, this apparently was a known problem. Based on recommendations from those same forums, the Open_G libraries where removed and the Read/Write Anything libraries from MGI (Many Good Ideals). This fixed the issues with the variant data types but resulted in a different text format for the ini files. Actually, it is a cleaner and easier to read format when compared to the Open_G files.
Other changes to the IMS_Common toolbox libraries include:

• LIME_LV and LWS DROP_BOX libraries: Updated to reflect changes in the new web services and improve functionality in the Sample Information window vis.
• TIME library: Add a Wait Time vi that replaces LabView express vi with the same name.
• TRANSFORM library: Added this library, which contains vis for transform matric manipulations. Used by the SRM program for sample axial rotations.
• SYSTEM SPECIFIC library: This library contains both vis and controls that must be shared between the DAQ and INST modules of a particular track systems and therefore cannot be contained with private access scope in their libraries. Primarily supporting the SRM and WRMSL tracks.
• PHIDGET library: This library is not in a stable state at this time. It contains both 32 and 64-bit versions and vis that need to be moved to the SYSTEM SPECIFIC library. Use caution when working with these vis until we can get them sorted out.
• ID library: Added transform matrix controls.

DAQ Module changes All tracks

• Sample Information back panels updated to be similar in structure and to accommodate the changes to the new web services.
• Outstanding: Need to check how each respond to a network or web service disconnect.
• SHIL DAQ:
• Fixed Section Information dialog to display WRNDs removed from a selected section.

INST MODULES

Magnetic Susceptibility:

• Removed the range check during normal acquisition, which was triggering false error when another instrument delayed the acquisition cycle. Range checking is now only performed during initialization and in utilities.
• Disabled instrument inter-calibration setup and utility.

P-wave Logger

• Remapped the transducer open/close command and timing delays to accommodate issues with the hardware.
• Updated the time pick module to extrapolate the zero crossing time between two points of data.

Outstanding Issues:

• Using the Standard editor can corrupt the configuration file. Does not happen every time. The cause need further investigation and remediation.
• The PWL calibration interface is too complicated. Easy to make mistakes. Also, should implement the telescope P-wave standard.

Sonic velocity (GANTRY)

• Operating with release 7, which changed the reported units from meters to millimeters for bayonet separation and sample thickness
• There is a new version of this software ready for deployment. It was not deployed on Expedition 362 pending thorough testing.

Thermal conductivity (TCON)

• No change. Third party acquisition software. Operating with vendor TCON release 5.0.0 build 7 since Exp. 335.Uploader utility. Changed on Exp. 362T to use new web services.

Moisture and density (MAD)

• Changed. Operating with release 3.1.0.2.
• Changed on Exp. 362T to use new web services.
• Fixed a couple of minor annoyances:
  • Formerly, if you performed a tare in the balance test dialog, the tare did not "stick". It would have to be re-done over and over if you wanted to repeatedly test the balances, or run something through other than a normal sample. This has been fixed.
  • Also in the balance test measurement dialog, there was no "cancel" button, and no other way to close the window without going ahead with the measurement.

Paleomagnetics Non-Track

JR6A SPINNER MAGNETOMETER

• No change. Operating with AMSPIN unchanged since Exp. 335.

Geochemistry

ICP Analyzer

• No change. Operating Coulometer with release 2 since Exp. 349.
• Outstanding issue: software is not subtracting the signal for the BLANK analysis from the signal for an unknown—as documented in p 35 of the manual.
• The last applied drift correction is wildly negative. Implies that software is applying an incorrect factor.
• Request that calibration plots include dashed 95% confidence lines bracketing the existing calibration lines.

Gas bottle monitoring

• No change. Operating with release 1 since Exp. 362T.
• Outstanding issue. Chemists request a larger font for the pressure read-outs—to enable it to be visible across the room. Work-around is to modify the CSS on-the-fly or ctrl-zoom.
• Applied Wireshark to capture traffic between the pressure capture device (DI-718B-E) and the Dev desktop computer. No further analysis has been conducted.

Development Tools and Frameworks

SQL Developer

• No change. Operating with version 4.1.2.20.64 since Expedition 360.

Other

MegaUploadaTron5001 (MUT)

• Changed. Operating with release 15.1.0.6.
• Modified to use new web services (This change was made on Exp. 362T).
• Fixed a problem parsing date/time stamps within track files.
• Fixed bug on GC3 where MUT would sometimes "see" two copies of each file.
• Fixed some of the uploader modules (notably the track file base, so this applies to all track files) so that they can parse a file that has non-standard line endings (e.g. CR only or LF only).
• Fixed a bug where multiple simultaneous uploads that reference the same file (e.g. IMS config files) could stomp on each other.
• Added a feature (sort of): new "MaxThreads" setting in Settings.xml determines the upper limit on simultaneous uploads. Set to 3 by default, can be set to more for testing (e.g. set to 10 to make threading issues that are hard to reproduce happen), or down to 1 to force one upload at a time.
• Change to JR6 spinner uploader to upload geographic-inclination and geographic-declination values.
• Fixed a bug that caused MUT to fail to process a track data file if the MULTI section contained a line on which a component appeared more than once.

LORE

• Changed. Operating with Release 14.
  • Modified to use new web services (This change was made on Exp. 362T).
  • Changes were made to the following reports:
    • Hole Summary List: modified layout of report and fixed "seafloor depth estimate method" bug (corrected in LORElib).
    • SRM (expanded and standard): modified to use new components created in upgrade to IMS.
    • MAD: modified report definition to exclude Incomplete MAD tests.
    • NGR: trim top-and bottom offsets caused all values to be removed from report (corrected in LORElib).

LIME

• No Change. Operating with Release 8.1 since Exp. 362T.
  • Modified to use new web services on Exp. 362T.

Thin Section Report Builder

• No change. Operating at version 2.0 since Exp. 362T.
  • Modified to use new web services on Exp. 362T.

Thin Section Report Writer

• No change. Operating at release 10 since Exp. 362T.
  • Modified to use new web services on Exp. 362T.

WebTabular reports

• These reports were aggressively pared down effective Exp. 362T; all Sample and Science report pages were removed; only a small number of Drilling summary reports were left in place since these reports are used by Ops and Siem drilling operators. These groups have well established work flows that rely on the specific formats presented by the WebTabular summary reports.

LIBRARIES

IODPUtils

• Many changes, almost all are small and related to application changes. Some highlights:
  • The user can now click and drag on the little message box that appears in the login dialog and move it. This is so that if something weird about the system causes that message box to obscure other controls, it can be moved out of the way.
  • Fixed a few bugs in the WSCaller class (mostly error handling, which could still be improved).
  • Rearranged the folder structure for source files so that things are easier to find (hopefully).
  • All apps now come up pointing initially to the server they were installed from, rather than whatever was selected last time the program was run.
  • Minor improvements to the "PleaseWait" form that's used in many apps.

LIMS.NET

• This library is no longer used.

NOTE: Effective Expedition 362T the following hardware and server modifications occurred

• All resteasy web services except resteasy-drillreport have been deprecated. All applications have been converted to use new IODP web services.
• Solaris servers were decommissioned and services running on those servers were distributed to new hardware:
  • All Oracle databases now hosted on Oracle Database Appliance (ODA).
  • ASMAN file server has been moved to virtual server Olympus.
  • Ararat, Rainier, and Shasta servers were decommissioned and Tomcat servers were moved to virtual servers Elcapitan and Matterhorn.
  • Apache Load Balancer was relocated to virtual server Olympus.

WAPPS libraries

WAPPS are a set of libraries that support applications and web services; they are designed to standardize a set of functions that are used across a variety of applications and services. With the Exception of ZedGraph all of the libraries in this collection were written as part of the web service rewrite project.

• AuditLib: Operating with version 2.0 since 362T
• AutherLib: Operating with version 2.0 since 362T
• DBOverviewLib: Operating with version 2.0 since 362T
• DescinfoLib: Changed. Current version: 2.4.
  • After calling FilesData.FileToDisk, it is assumed that the "fileout" value is an instance of the original file, if "oldfileflag" is set. That way, processing can continue on the file. Needed for DESC value lists processing.
  • ValueListData.setSubList and .setValueList now return "DESC-001: Success (duplicate found)" if a duplicate was found.
• DescLib: Operating with version 2.0 since 362T
• FilesLibrary: Changed. Current version: 2.4.
  • Numerous minor tweaks and fixes, mostly in FilesData.FileToDisk.

  • Fixed bug that caused seafloor depth estimate method not to display.
  • Modified report format to print in vertical rows instead of horizontal columns.
• MonitorLib: Operating with version 2.0 since 362T
• PrinterLib: Operating with version 2.0 since 362T
• QAQClib: Operating with version 2.0 since 362T
• ReferenceLib: Changed. Current version: 2.2.
  • Fixed PitaLogGet so it takes an extra argument for "maxrecords" so that it can format the query as SELECT * from (SELECT * from pitalog.log ... order by ...) where rownum < maxrecords
• ReportDefLib: Operating with version 2.0 since 362T
• SampleLib: Changed. Current version: 2.5.
  • Added code to add, remove, update and retrieve request code data.
  • Fixed sample reparent.
• SCORSlib: Operating with version 2.0 since 362T
• Utility: Operating with version 2.0 since 362T
• RibbonBar: (.NET) Unchanged.
• ClickOnceReinstaller: (.NET) Unchanged since 362T

The libraries below are third-party or special-purpose libraries we maintain in our SVN repositories.

• ZedGraph (.NET)

Web Services

• Auther: No change. Operating with Version 3 since Exp. 362T.
• ChangePassword: No change. Operating with Version ? since Exp. 362T.
• OVERVIEW: No change. Operating with Version ? since Exp. 362T.
• WRIMG: No change.
• WTR: No change. Attempted to retire. Still in use, only Core Tech Sheet, Hole Summary, and Core Summary reports remain in place.
• autherR: No change. Operating under 1.0 effective Exp. 362T.
• autherW: No change. Operating under 1.0 effective Exp. 362T.
• filesW: Changed.
  • Made changes to the underlying filesLibrary so that if a duplicate file is found, the library call opens up the original and returns a reference to it, so that the caller can continue any processing with that file. This was needed for some of the DESC value lists services.
  • Fixed a bug: the underlying library was looking for duplicates using the passed-in catalog name, rather than the one from the database.
• limsM: Changed.
  • Fixed problem in LORE NGR standard report to correct section top-and-bottom trimming.
  • Corrected a problem where alternate-scale headers were showing up as "zzzscaleName".
  • Changes related to reporting (added "calc_columns" and "post_sort" features that can be included in report definitions, although it turns out we didn't need them yet. Paul thought we should leave them in in case we do need them at some point).
  • Changed (1 October 2016) limsM POM file modified to include dependency on LORELib version 2.5, no changes to limsM source code.
• limsR: No change. Operating under 1.1 effective Exp. 362T.
• limsW: Changed.
  • Fixed ReparentSample to use original_sample from new parent. It was setting original_sample = sample_number, which was wrong.
  • See the change described for filesW. This service was updated to use the new version of the library, and it's processing of uploaded value list files changed so that they go ahead and process the file even if it's a duplicate.
  • When new HOLE samples are logged, don't create the LATLONG and ORIGDEPTH tests unless corresponding non-empty values exist in the data passed to the service. Otherwise we just create empty tests that never get data put in them, and then SampleMaster goes and creates other tests with the values.
  • New services to add, update and delete request codes.
• logs: No change. Operating under 1.0 effective Exp. 362T.
• printer: No change. Operating under 1.3 effective Exp. 362T.
• reference: Changed.
  • Added RequestIdFromCodeGet service for SampleMaster
  • Added PitaLogGet service and related services.
  • RequestCodesGet now accepts a parameter to let the caller select whether to retrieve only the codes as a JSONArray or strings, or the entire records as a JSONArray or JSONObjects.

Labview svn repository

On Expedition 362 the SVN repository https://build.ship.iodp.tamu.edu/svn/ims/ was renamed to https://build.ship.iodp.tamu.edu/svn/lv/. After the rename the following projects were exported from https://build.ship.iodp.tamu.edu/svn/jrlv/ to the lv repository:

• Alkalinity
• Analytical Gas Bottle Monitor
• DHML
• LazerKatjie
• ngr
• ngr_pos
• PasswordMaintenance
• Underway Geophysical Apps
• Velocity
• Acuity AR 1000 Laser Class

Projects in jrlv NOT exported to new lv repository:

• EventsExample
• IMS
• IMS Common
• msl
• SHIL
• SHMSL
• SRM
• SRM Survey Mover
• SRMUturn

Solaris Tomcat Server

• Sites. No change.
• labnotebookWebDav. No change.
• resteasy-asman. See description of change above. Operating at release resteasy-asman-4-PJR-20151017085744-dev since Exp 359.
• resteasy-image-tiling: No change. Operating at release 2.0.0.1-PJR-b12-20110905111358-fackler.

Developer Resources

Office Space

• Changed on trial basis. Developers on expedition 362 took half of the E & O office on the F-Deck. Near the end of the expedition one of the developers (Tim) returned to working in Lower-Tween office due to the noise and distractions in the more crowded office upstairs, and also so that he could play music over the speakers without bothering anyone. We will do a post-expedition assessment to determine whether to continue sharing the office on F-Deck with E & O representatives.

Desktops

• No change.

Servers

• Load Balancing. Olympus is configured to be in the load balancer, but it is by default disabled. Elcapitan and Matterhorn are virtual servers and all web service traffic was routed to these two servers during Expedition 362T. We only observed two instances where the servers became overloaded and stopped responding; analyses of these incidents revealed that they were caused by an ill-formed SQL query in an isolated web service. That service was modified to throttle the data return and there were no other instances of problems with the Tomcat servers.
• SHIPT. A ship test environment has been setup over several expeditions. The current ship test environment consists of
  • Upgraded to Oracle 1.8 for new web services testing.
  • Oracle Data Appliance (ODA).
    • Data from 360, 361, and 362T have been loaded on the system.
• BuildJR. No change.
  • Java 8u66 JDK
  • SQLDeveloper 4.1.2.20.64
  • Adobe Flash Player 20.0.0.286
  • Microsoft Silverlight 5.1.41212.0
  • Adobe Air 13.0.0.83
  • Fiddler 4.6.2.0
  • Notepad++ 6.8.8
  • Mozilla Firefox 43.0.3
  • Novell iPrint Client 06.02.00
  • LabVIEW 14.0.1f3 patches and driver updates
  • Novell GroupWise 14.0.2.120664
  • Microsoft Visual C++ distributables for 2008, 2012, 2013 x86, x64 products
  • Adobe Reader XI 11.0.08
  • WinSCP 5.7.5
  • 7-Zip 15.07
  • Nexus repository manager 2.11.4-01
  • VisualSVN 3.4.2 was updated prior to Thanksgiving. The shipboard copy was revised to run as the DEV user to avoid file permission issues that were preventing logins and check-ins.
• Environment configurations. Change these server platforms to meet your production, development, and testing needs.
  • The BuildJR Tomcat is configured with trunk builds of web-services and applications. These address the production environment (PJR).
  • BuildJR carries an apps distribution directory. Test applications targeted to the production environment may be distributed there.
  • The Nexus repository manager is configured to proxy the shore repositories necessary for old web-service and new web-service and application builds.
  • ODA. The Oracle data appliance carries complete sets of data from several expeditions. It is a great convenience and relief to be able to test some of the more complex issues we see in a completely separate and independent environment. Even a PITALOG instance is present there for new web-services use.
• Database modifications. These changes were applied to the test environment, and later on to the production environment.
  • The way depths are handled has been modified. The management of inputs related to depth computation is completed separated from the activities of depth computation. The older depth computation scheme is retired (depth-services + activity from set_sample_depth). Only one depth computation set is run and when stored in x_sample_depth, they are immediately copied over to the sample.x_sca_depth_top, bot fields.
    • Removed LIMS.SET_SAMPLE_DEPTH, LIMS.set_x_curr_len.
    • Removed LIMS.FNC_COMPUTE_DEPTH
    • Removed triggers LIMS.trg_depth_change_ai, LIMS.trg_depth_change_aifer, LIMS.trg_depth_change_before.
    • Removed package LIMS.depth_state_pkg.
    • Added trigger LIMS.maintain_orig_len. Maintains x_orig_len, x_length for COREs based on change to section inputs. Maintains x_orig_len, x_length, x_advancement for HOLEs based on change to core inputs.
    • Added procedures LIMS.CORE_maint and LIMS.HOLE_maint which implement the rules for maintaining core and hole sample table lengths. No longer maintaining x_curr_len for these sample types.
  • Unused column indexes have been remove in all environments.
    • drop index lims.sample_customer45;
    • drop index lims.sample_parentaliq;
    • drop index lims.sample_charge_c591;
    • drop index lims.sample_product6772;
    • drop index lims.sample_project13866;
  • Removed these convenience triggers. Current syntax obviates the need for them
    • drop procedure lims.disable_result_triggers;
    • drop procedure lims.disable_test_triggers;
    • drop procedure lims.disable_sample_triggers;
    • drop procedure lims.enable_result_triggers;
    • drop procedure lims.enable_test_triggers;
    • drop procedure lims.enable_sample_triggers;
• AD/DEPLOY. The directory structure here is flattened somewhat. Where there are WAR distributions no sub-directories are needed. The distribution scripts have been modified to accompany the change. WAR files must carry at least a version number to distinguish them in the directory.

MIKE HODGE AND MINH HUYNH

Servers (Microsoft):

• At beginning of Expedition 362 EPM notified shore that various URL links were not resolving within Cumulus after BOX shore import of files. It was discovered that user roles and passwords did not transfer correctly from shore's backup into ship Cumulus system. Moksa (the vendor) or MCS could not determine if data was not collected in backup or if it was not properly uploaded. Moksa is to work with MCSs on Expedition 363 and verify shore backups are correct and work with MCSs in uploading shore data into ship system.
• Encountered one instance where one of the Microsoft servers had hung on August 24^th. During routine check of Acronis backup status server Moaunaloa was found in a hung state. Reboot of server resolved matter and no further incidents for remainder of expedition.
• Server cleanup was run on the Windows Server Update Services (WSUS) resulting in a reduction of the updates database. This action ensures that the server and clients will run optimally and is taken according to best practice.

Servers (Linux):

• On August 16th Developers contacted MCSs about Tomcat services were not responding. Investigated Tomcat servers ElCapitan and Matterhorn and found them unresponsive. Logs in /opt/tomcat/logs revealed service Java had ran out of memory. Rebooting the servers released memory issue and allowed for Tomcat services to come back online. Outage was approximately 30 minutes in duration.
• Because of the Tomcat incident on August 16th the Developers requested a third Tomcat server be provisioned. Tomcat server Urulu was stood up for Developer's testing requirements.

Servers (Solaris):

• Solaris servers Etna and Pico were retired and packed up into freight for shore, to be surplus. This section to be removed from future reporting.

Servers (ODA):

• During routine check discovered not able to login to Oracle ODIE2 root account. Was able to ssh into server and reset password.

Servers (VMware):

• No issues to report concerning VMWare server or services.

EVA4000 SAN:

• HP EVA4000 was retired and packed up into freight for shore, to be surplus. This section to be removed from future reporting.

3PAR SAN:

• No issues to report concerning HP 3PAR SAN.

Network:

• New DNS & DHCP servers were implemented during tie-up period prior to this expedition. Discovered various Macs and PCs workstations with old DNS server IP assignments. Changed these workstations to reflect new DNS server IP assignment. On internet stations this mitigated workstation from bypassing ship DNS server and forwarding DNS requests to shore DNS servers on TAMU campus.
• The Extreme Network ETS-TAG server was configured with old DNS server address. ETS-TAG server was reconfigured with correct DNS server address.
• Upon discovering that a recent update to Adobe Acrobat enabled the Adobe automatic update program on Windows workstations, the MCS disabled the update component over the wire on the PCs across the network. Adobe updates are blocked by the firewall, so there is no need for Adobe products on workstations to attempt downloading updates from Adobe.

PC Workstations:

• About a dozen PCs had lost their Identity Finder agents around June 8. ZENWorks was used to push the existing bundle of Identity Finder Agent Version 8.1 to those computers. All computers in Identity Finder are now reporting correctly.
• Encountered several PC workstations where McAfee On-Access Scanner (OAS) became disabled. When McAfee OAS becomes disabled the NAC Agent quarantines the workstation denying network access. Updating the workstation's virus definition DAT files and reboot generally cleared the problem. However, a service request was opened with McAfee and they provided 4 registry values that need to be confirmed set and then restart McAfee service. This fixed the issue when encountered and no further McAfee incidents on affected workstations.
• It was discovered that the Downhole Measurements Lab (DHML) PC52698 computer's time stamp varied from Rigwatch's time causing issues with data time stamps from tools verses Rigwatch's server time. Specifically the DHML was losing several minutes per week causing time stamp on instrument data to not correlate with Rigwatch time stamps of drilling events. To mitigate the time loss before a scheduled time resynch, a daily time sync task has been added to the scheduler on the DHML computer.
• PC52845 was reimaged from a Zenworks image and configured to replace original SRM PC52708. PC installed during first week transit and operational whole expedition. Also, installed second touch screen monitor RF53024 on SRM PC. Second monitor for track control and primary monitor for data visualization and secondary track control.
• XRD technician requested Diffrac Plus DQuant software to be installed on existing workstations where EVA software currently installed. DQuant installed on following workstations;
  • Installed on XRD PC52710
  • Installed on Corelab PC52519.
  • Installed on VCD2 PC52511
  • Installed on Userroom PC52487
• MCSPC1, one of two management stations in the MCS office had to be rebuilt. The system suffered stop errors caused by a device driver that did not properly uninstall. MCSPC2 remained operational throughout the process and was used to clone MCSPC1.

MAC Workstations:

• Publications (YEOP) MAC52629 workstation repeatedly requested Keychain password everytime YEOP would login to the Mac. MCS was able to reset the password via "Change Password for Keychain "login"" within the Keychain Access app. However, upon reboot to confirm fix other Keychain entries opened requesting passwords that were unknown. They were probably created during tie-up period for personal use by individuals utilizing this station.  MCSs discourage Keychain usage in ship environment.  A crew rotation occurs and on-coming party does not know the passwords created but, the workstation dogs the user with messages to enter password. All keychain entries were removed so no further Keychain password prompts persist.
• The 19" monitor (RF53814) on PMag MAC52635 was replaced with a 20" widescreen model RF51849. Scientist complained that the old monitor caused eye fatigue. MCS did verify that the monitor's video was blurry when viewing text. The 19" monitor had two blank records in AMS that MCS was not able to correct. An email was sent to shore to seek assistance to correct the monitor's AMS record. After AMS record issue was resolved the monitor was placed in freight for shore to surplus.
• Publication's PC52498 encountered multiple loss of network connections at beginning of expedition. Review of NAC agent said workstation was in compliance but, when opening a browser to JR homepage would result in an assessment loop. The assessment was successful but, loop back into another assessment when attempt at network connection. Multiple steps to troubleshoot were performed from swapping out local Netgear switch and NIC cable but, these steps did not resolve matter. Final solution was direct connection from PC to LAN F44-023 port and computer would function correctly. The Netgear switch was moved to LAN F44-021 and connect both MAC52629 & MAC52625 (port window). No further incidents remainder of expedition. Fix implemented Aug 26th.
• Updated Mozilla Firefox to version 45.2 ESR on all Macs utilizing Apple ARD utility.
• Mac OS X patch 2016-005 has been deployed to All Macs.
• Multiple Mac VDUs were discovered with their Wi-Fi radio turned on. Using MCS Apple ARD utility tuned Wi-Fi off on all Mac workstations.
• MCSs and Developers were locked out of Dev's MAC52627 workstation. OS and software had to be re-installed.
• A case has been created with Extreme Networks (case # 01245363) regarding the NAC agent crashing, exiting or hanging on Mac workstations. A diagnostic session was started on Userroom MAC52622. Seven days after the diagnostic began, MAC52622 logged a disconnection. Log files from the NAC Manager were sent to Extreme Networks for analysis. A NAC agent crash on a different Mac was determined by Extreme Networks to be unrelated to the issue under investigation.

Printers:

• Coredeck color printer RF53031 encountered some event that caused damage to the installed JetDirect card and physical Ethernet port. The Ethernet cable now no longer will seat firmly in its socket and will come out far enough to cause network disconnection. The Ethernet cord has been rewrapped with Velcro to limit movement. Replacement card has been ordered and to be shipped to Exp363.
• Server upgrades during recent tie-up period caused some incompatibility with Sharp Copier on Foc'sle deck and the Novell file servers. Users could no longer scan documents directly to a network folder on a Novell server. Windows server Hood has been configured to be a redirector for network scans from the Sharp copier en route to Novell server Novarupta. This is a workaround solution until a fix can be identified for Sharp Copier.
• The two HP5200 printers (MCS & CTShop) were replaced with existing HP4350 printers in spares. The replaced HP5200 printers were packaged into freight for shore to be surplus.

Satellite/Internet/Phones:

• Discovered rack rails for Riverbed WAN Optimizer in VSAT cabinet shipped from vendor were wrong type. Contacted vendor and had correct units shipped to IODP. In freight for Exp363.
• VSAT outages:
  • Aug 9^th - Bow antenna stop tracking satellite on 9Aug. Power cycled PDU restored bow antenna operational.
  • Sept 1st - At ~1:45 AM ship time Rignet started the AT&T fractional T1 circuit migration to new virtual Ethernet circuit hosted by Phonoscope. The migration took ~hour to implement. Immediately notice increase in bandwidth from ~1.3MBs to ~1.9MBs. Youtube videos streamed with minimal buffering. Was able to download a ~12MB file in 77 seconds. Phone circuits functional as per call from shore and was able to call shore without issue.
  • Sept 8th - VSAT outage occurred between 6:35AM and 7:20AM. F18 Below Deck Equipment was inspected and no error or alarm conditions indicated, both domes were tracking satellite. Rignet support was contacted. It was later determined that routing tables within JR Cisco router had become corrupted. Power cycling Cisco router restored operational.
  • Sept 18th – Both dome antennas lost satellite connection and went into search mode when the ship made a sharp turn to starboard. Outage was around 20 minutes.
  • Sept 24th – Lost internet connection around 10:07 PM. Below Deck Equipment did not indicate any issues. Shore check discovered that shore did not have internet connection either. Confirmation by shore personnel indicated TAMU IT campus was working on IODP network connection and had interrupted data connection. Phones service was operational.
  • Sept 25th - Another unscheduled TAMU IT network outage occurred from 5:00 PM to 5:56 PM and again at 9:00 PM to 9:55 PM ship time.
• Sept 13^th – received email notification that the Autumn Equinox for 2016 was to occur Sept. 21^st thru Sept. 29^th for ship and again Oct. 6^th thru Oct. 15^th. Outages were first encountered on Sept. 19^th and concluded on Sept. 29^th.

Other Equipment/Projects:

• Researched and resolved Autocad versioning and installation confusion. OPS PC and CTShop PCs are only two authorized Autocad 2017 installations on JR. All else are to use DWG Trueview for viewing Autocad files. Downloaded Autocad 2017 and received license from shore. Proceeded and finished installation on designated workstations.
• Sassafras K2 has been successfully deployed on the ship to collect software licensing data on shipboard computers. Data collection is on-going. The previous software inventory and license compliance software Flexera has been depreciated, replaced by Sassafras K2.
• Sun servers Etna and Pico, OES Cluster Servers Ararat, Rainier & Shasta, server rails and HP EVA4000 have been pulled from server room racks (LTDAT) and in freight for shore.
• RF52786 Dell WXA2000 appliance in F18 VSAT locker removed, packed and in freight for shore.
• Surplus Dell Augmentix laptops.

• Haivision decoder unit for VIT video streams was successfully installed on OPS office TV per OPS Manager's request. Decoder connected to HDMI port 2 on TV. Network port for decoder is LAN-035 (ge.1.3) and was configured for VLAN 90.
• MCSs in coordination and directive from Developers have standardized on software Correlator v2.1-RC2 for Stratographic Correlator MAC52767. All prior versions have been deleted due to software issues.
  • NOTE: Corelyzer has been depreciated for ship environment. IODP Developers no longer support it. We are to keep for those scientists whom demand or require it but, they are to self-support if software issues are encountered.
• The WinFrog2 computer generating positioning data in Underway lost connection to the ship's network on multiple occasions during the expedition. Troubleshooting did not find any misconfiguration in Windows that had caused the disconnection. The network cable connecting the PC to the network switch was replaced. During the Cape Town tie-up period, large items were stored behind the server rack which could have damaged the cable.
• The Uninterruptible Power Supply (UPS) in the Thermcon area was connected to the network. This is part of a larger effort to network-enable all of the Minuteman UPS on the Core deck to allow the Electronic Technicians to more efficiently monitor their performance.
• MCSs worked with LO & ALO to compile a preliminary listing of locations for new 27" monitors to arrive on JR for Expedition 366. New desk stands with arms to accommodate the larger monitors is still under review.

Engineering Report

MIKE MEIRING and DEAN FERRELL

ENGINEERING

OVERVIEW:

• Multiple deployments were planned with the SLB-Wireline /ERS/MDHDS/T2P combination. The T2P was extensively damaged on the first deployment and further deployments were put on hold.
• The VIT was deployed in water depths <4000m for the first time, without any issues. Two of which exceeding 36 hours. VIT was dropped ~6m onto the FFF due to an operator's error. No apparent damage.
• A new single window control application was written in LabView.
• No evidence of changes in optical attenuation, implying the optical fibers are well isolated from any destructive forces within the cable.
• VIT tensiometers did not hold up in the harsh environment in the moonpool area. Parts are on order to address the issue. Mounting position also to be revisited to avoid removal/mounting on cable for each deployment.

VIT System:

GENERAL

• Multiple deployments were made to <4000m with no issues. Two deployments for <36HRS.
• The new SeaView Systems multiplexer cards functioned without any issues.
• No evidence of changing attenuation in test fiber.
• Adjustments were made to "Near Focus" of both HD cameras to prevent them from focusing on objects on the pressure vessel window.
• Opened Re-entry cam S/N2 to remove foreign particle from port window. Replaced O-ring 2-018.
• Pan/Tilt faulty. Spare unit on order. Expected Exp 366.
• Populated AMS with VIT critical spares list and adjusted stock levels.

SOFTWARE

• New Software – HD-VIT Control 2016 V1.0
• The VIT control software has been updated to incorporate all of the VIT control functions into a single user Graphical User Interface (GUI), with the exception of the proprietary Sonar software. LED control, Pan/Tilt control, Camera Zoom and focus as well as Gyrocompass display are all controllable within the single "HD-VIT Control 2016V1.exe" executable. The GUI defaults to a "Simple" interface with fewer tabs and visible controls. An Advanced GUI can be selected via the "Interface" menu. The advanced interface allows the use of additional commands and diagnostic and debug data.

New in this Version 1.0 :

• Single window Operation
• Automatic Ships Heading and Latitude
• Ships Heading displayed on Gyro (Blue Needle) for ease of determining relative camera direction
• Simple and Advanced Graphical User Interfaces
• Additional Controls
• Improved Gyro drift correction for earth's rotation

TENSIOMETER

Overview:

• Payout calibrated to the Siem Veeder Depth meter. Calibration factor = 22.999p/min.
• Both tensiometers failed during deployments. 354A as a result of water ingression into j-box and 355B TBD. New j-boxes to be fitted and extra measures to be taken to prepare the units for working in the harsh environment in the moon-pool area.
• Repositioning of the tensiometer on the cable to be considered to avoid mounting and dismantling the unit for every deployment. This task is cumbersome and the potential of dropping parts while assembling/dismantling tensiometer over moonpool is high.
• j- boxes and m A Converters on order.
• Created spares list in AMS

DOWNHOLE TOOLS

T2P/ERS/MDHDS DePLOYMENT

• Only one deployment was made resulting in the T2P being damaged beyond repair.
• From the RIS and T2P data it was determined that the pins sheared and MDHDS de-latched prematurely when landed in the BHA. The T2P suffered buckle damage when it could not penetrate the sand formation and the push force from Standpipe pressure at 1200psi was more than the T2P could support.
• Lessons learned:
• Do not deploy in sand.
• Shearpin design to be revisited.
• Standpipe pressure to be limited to 600psi when deploying the T2P.

ERS

• A new motor was installed and motorcan filled with water.
• ERS release of MDHDS in BHA were normal.
• "Tool present" indication did not function.
• ERS failed to attach to MDHDS. Probably due to sand in the cavity for "Tool Presence" switch.
• Water drained from motor-can at end of expedition.

MDHDS

• Tool was not maintained following Exp 359. However, it was layed out and latching mechanism appeared to be operating normal.
• Pins sheared prematurely when landed in BHA.
• Following the deployment, the latch was rebuilt, assembled and tool placed in the shuck.
• Reccommendations from TomP and PeterP following failure:
• Never deploy in sand
• Limit standpipe pressure to 600psi
• Add step to verify tool is latched to deployment procedure.

T2P

• T2P tool DAQ1 was assembled and when pressure tested it was found that Tip pressure did not release. Disassembling the tool we found obvious damage to the shaft o-ring.
• After consultation, it was decided to omit one of two o-rings on the TXD-block which cured the issue above.
• Dimensions of the big porous ring is critical at 0.2". Any smaller, the porous ring seal between shaft and TXD-Block is compromised. Any bigger, the small o-ring seal for thermistor-shaft through TXD-block is compromised.
• During the actual deployment the thermistor constant current source was interrupted, causing a shift in the A-D Vref.
• The CDAQ stopped recording data shortly after the T2P fell through the bit into the formation. At the time of failure, Mud pumps were running with Standpipe press around 1100psi.
• Two MDM/GREENTWEED/FISCHER connector harnesses were re-wired.
• Reasons for failed deployment as stated by TomP and PeterP
• OT 7043, coupling from T2P to MDHDS, no fit. A spacer ring had to be machined as a work-around to couple T2P to MDHDS. BobA working on an Eng change.
• T2P to stay onboard for Exp 366
• PeterP to arrange for spare parts below to have a 2^nd T2P ready for Exp 366:
