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

The objectives of the expedition: Investigate the interaction between climate and the Agulhas Current during the Plio/Pleistocene. Six drill sites in the southern Indian Ocean and Mozambique Channel will determine (1) the sensitivity of the Agulhas Current, (2) the dynamics of Indian-Atlantic gateway circulation, and (3) the connection between Agulhas Leakage and shifts of the Atlantic Meridional Overturning Circulation (AMOC) during major ocean and climate reorganizations of the past 5 Ma. In addition, the Agulhas Current Density Profile ancillary project will attempt to reconstruct temperature and salinity of a depth transect during the last glacial maximum.
Operations: Leaving from Port Luis, Mauritius, we completed a 6 day transit to our first drilling location off the east coast of South Africa. Due to delays in receiving drilling permits from the Mozambique government, the ship headed south into the Southern Ocean to core on the Agulhas plateau (after a quick detour for a medivac). On a lot of optimism that drilling would be permitted, the ship headed north back to the Mozambique Channel sites. After about two days of sailing north, the ship heaved too and made up drill pipe while waiting for approval. Finally giving up hope, the ship headed back to the Southern Ocean drilling sites. After a few hours into the transit, we finally received drilling approval and turned the ship around and headed back north once again.
After successfully coring the shallow Mozambique sites, the ship headed back to the Southern Ocean to drill the final site of the expedition, just 8 hours from Cape Town.
Labs and Technical Services: Overall there were few serious hardware issues that were critical to the expedition. We lost all three Icefield orientation tools on the first site due to current induced drill string vibration. Fortunately, we were able to complete the expedition using the older Flexit orientation tools. Our data upload application (MUT) was problematic throughout the expedition, failing to recognize new files and initiate the upload process without manual intervention. The issue was finally resolved with an extensively modified version.
On the previous expedition they had numerous crashes on the SHIL. We only had a couple at the beginning but nothing afterward, other than issues with the light controllers not responding to commands, the software was stable.
This expedition saw the successful release of the IMS track software for the WRMSL and STMSL systems.

Lab WorkING Group ISSUES

• Internet access was greatly improved once the Riverbed appliance was brought online. Strongly recommend that we pay for this service after the trial period is over.
• 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.
• PWL hardware is worn and the mechanical design is not capable of keeping the transducer align causing errors in the LVDT displacement values.
• The WRMSL and STMSL rails are worn out and need replacing.
• The AR200 lasers are old and will no longer retain settings when the power is cycled. Need to be replaced.
• 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? It hasn't 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. And contribute science at the same time!

Core PROCESSING

• 6 sites were occupied and 35 holes attempted. A total of 8,311 samples were taken.
• The vessel cored 5080.4 meters and recovered 5175.69 meters of core.
• The nearly perfect APC cores allowed for the collection of excellent high resolution track data.
• Core collect in the shallow site where gassy and caused the usual curation headaches with expansion.
• The core backlog at the shallow sites was managed well by the staff and science party. Additional rack space was setup in the Down Hole lab.
• In addition the standard shipboard analysis over 544 IW samples (167 shipboard/382 APL) where processed.

U/W Geophysical activities

• The ship was in transit for 26 days for a total of 6717.25 nm at an average speed of 10.8 knots (14.3 max).
• On site: 30.1 days
• Including on site DP motion, the total distance travels was 6852.84 nm
• Bathymetric data was collected on all transit (weather permitting) and magnetic data was collected on the long transits across the ocean basins.
• All logging was canceled due the drilling permit delays and therefore, none of the planned VSPs were conducted.

LOGISTICS

• The paleo lab sieve inventory has been removed from the Paleo Lab and moved to the UTS. All brass sieves have been removed from inventory so that we only stock stainless steel in the future. Some sieve sizes have been removed from AMS inventory and placed in drawer 20D-6. These sieves do not seem to be used much but will remain onboard to see if they are really used and should be placed back in the lab and on inventory. A few new sieve sizes were added to inventory and a few sizes set for reorder based on comments from cruise evaluations. New sieves should go to drawer 20D-3 and checked out from there.
• With both X359 and X360 getting less core recovery that expected, as well as such long lead times for shipping, we have enough d-tubes and core boxes for 7000m of recovery. Six pallets are on the bridge landing, tarped and protected from the weather (a total of 66 boxes of d-tubes), plus we have approximately 90 boxes in the bulk storage area. Around 20 boxes are located outside of the B-rad van. We have used all the d-tubes from the core reefer first.
• Several of the pallets of core that were sent to Kochi had steel-banding that snapped and/or boxes sliding over. It has been suggested that we use three straps of banding in the future, as well as plastic wrap. It is important to spread out the core and fill containers full. If there is a small amount of residues, they can be placed on top of a lower stacked pallet of core. Also, dry containers have larger internal dimensions than reefers so additional dunnage bags may be needed to fill up the extra space.
• Replacement seats for the Herman Miller chairs that were wearing were received and replaced. An additional seat remained for future replacement. Replacements for the thin cushion that goes under the front seat of the chair will arrive in 361P shipments.
• Replacement seat mechanisms and pneumatic cylinders for Biofit seating were received and chairs repaired. There are extra seat mechanisms and cylinders stored in a box in UTSHOP and additional parts are coming in the 361P shipment.

OFF GOING SHIPMENTS

• Three refrigerated containers for core, and dry container for surface freight that will be loaded during the tie-up period.
• Regular and Foreign Air Freight
• World Courier
• WRMSL C-137 source

Equipment modifications

catwalk arbor press

An Arbor Press was installed on the catwalk to help recover hard core catcher material and minimize damage to drilling equipment. The press needs to be cleaned and greased between sites to prevent rusting and maintain proper functioning. The current optimal grease mixture is equal parts marvel mystery oil and lubriplate.
To operate the press simply hold an empty core catcher liner underneath the metal stand (Figure 1). One person can operate the Press by themselves, however, an additional person or bucket to hold the core catcher liner underneath is useful. The addition of an adjustable table would make use of arbor press more efficient and easier. Figure 1. Technician operating the Arbor Press to retrieve core catcher material.

Lazerkatjie

• The program will now reset the engraving size to 'FULL' after refreshed.

Procedural Issues and Solutions

label printers

• Labels within the printer frequently became stuck inside of the machine, creating a residue of adhesive. Residue occurs in two main locations: the metal feeder bar, or back-plate, and the print-head assembly bar (Figure 2).This residue leads to more labels becoming stuck and extra ink residue causing misprints. Several steps have been taken to remedy this:
  • The metal feeder bar, the largest source of residue, has been tied and is no longer in contact with the labels
  • Application of carwax to metal parts
  • Frequent cleaning of sticky areas with isopropyl alcohol – acetone is not recommended as it could melt plastic parts

Figure 2
Inside of core lab label printers
A: Depicts inside of the label printers showing areas that need to be cleaned regularly
B: The metal bar of the printhead assembly can accumulate residue
C: Metal feeder bar (backplate) lifted off the labels to reduce contact and residue buildup. Area should be cleaned regularly
The shelf life of Weber Label ribbons is one year. There appears to be differences in the labels. An offending roll is to be returned to the vendor for analysis and hopefully a fix.

contingency core racks

Figure 3:
Two constructed core racks for additional space.
A: Behind view of rack on underway bench
B. View of rack from core lab
C. Rack placement in underway lab Two additional core racks (Figure 3) were constructed to accommodate high recovery in shallow waters. As illustrated below, the racks were placed in the underway laboratory and on the bench. Bungee cords were used to help secure sections and better separate multiple cores. Assembly and disassembly are fast and is recommended if additional space is needed on high recovery expeditions. Spare core racks are stored in the upper tween next to the electric palette lift.

OUTSTANDING ISSUES

zebra label printers

Label Printers will not retain ideal darkness and position settings. This leads to partially printed labels or labels to dark to be scanned. The printers were reprogrammed and the issue occurs less frequently, but still happens.
To change printer settings open up a web browser and enter the IP address of the printer as if it was a webpage (Figure 4). Click view and modify printer settings. This will prompt you for a password, which is 1234.
Figure 4: Home page of printer configuration.
Once you are in the view and modify printer settings (Figure 5), you can click either general or advanced setup. In general setup you can alter either the darkness or the top offset (Figure 6). Current settings for darkness and top offset are 10 and 0 respectively. In the advanced setup you can alter the left positioning (Figure 7). Current settings for left position is -10.
Once you have changed a setting click submit changes. This will transport you back to the home page. The most important step is that after you have clicked submit changes you click View and Modify Printer Settings, and then you click Save Current Configuration. If you do not click Save Current Configuration the new settings will only last for a short time. This problem arose early on in the expedition, leading us to change the printer setting daily.
Figure 5: View and modify printer settings page. From this page you can access either general or advanced setup.
Figure 6: General setup for printers. In the general setup you can alter either the top offset or darkness settings.

Figure 7: Advanced setup for printers. The advanced setup allows alteration of the left positioning.

Rock saw

The Rock saw was taken apart to install an aluminum shield surrounding the blade to better direct water onto the saw. The new shielding did not fit onto the saw and should be completed during the tie up period.

CAT WALK

Drains on catwalk became clogged multiple times during this expedition. Drains should be checked and cleared more regularly, especially on high recovery cruises.

CORE Description, SEM, XRF

Sandra Herrmann

Summary

Expedition 361 was planned as a high-recovery sediment expedition. Eight core describers used the description tools in the sediment laboratory. The templates for macroscopic and microscopic description were kept very simple due to the expected speed and amount of core recovery. Six paleontologists with expertise in planktonic foraminifera, benthic foraminifera, nannofossil, diatom / radiolarian sailed on expedition 361. Templates were created for each microfossil discipline.
The SEM was used to image mainly micropaleontological samples, but also a few magnetite minerals.
The Micropaleontology Wet Laboratory was used for all paleontological disciplines.

ISSUES/To BE noted

DESClogik

• The DESClogik version (14) that was deployed at the end of EXP360 and was rolled back to 13.2 in port call. Version 14 crashes when trying to work with value lists.
• A new version was released (13.2.1.0) in the 2nd week of the expedition. This version allows to create and use templates with more than 500 columns. The recent version allows up to 1000 columns. The feature mainly helps paleontologists (diatom scientist on this expedition).
• Previous version 14 and version 13.2.1.0 were merged, tested and deployed after extended testing before drilling U1476.

BUGWIN

• At the beginning of the expedition a bug was discovered that prevented BugWin from pulling samples out of the LIMS database. The developers on this expedition re-established a database table that was deleted on EXP360. This fixed the issue. For more information details in the developer log.
• BugWin was introduced to the scientists prior to arriving on the first site.
• A slight modification of the program was requested during transit to the first site: When using abundance codes in BugWin, the program still displayed a 1 when clicked to enter a code. This was changed to display a P, as in present.
• The scientists decided not to use the software. They used the provided general log sheets for paleontology and Excel worksheets based on their DESClogik templates.

MICROSCOPE LAB

• The sieves in the paleontology preparation laboratory are a subject of discussion and complain for a while. I searched method chapters of all sediment expeditions back to Expedition 307 to scan for 'most used sieves' (see table below). I also asked the current group of paleontologists and used input from the staff scientists. Result: Stainless is preferred over brass. Main sieve sizes that should be in the lab in abundance are listed in the table below. All the information provided was discussed with ALO Crowder.

• The sieves not listed here were removed from the paleo lab and stored in the IODP store room (IODP store). The scientists can still request those sieves during expeditions. These requests will be monitored to later decide which sieves can be taken of the ship.
• Another discussion this expedition was about BORAX vs. CALGON for cleaning/disaggregating the foraminifer sediment. The scientists requested BORAX because it is 'cleaner' than CALGON. However, they tried CALGON and were perfectly happy about it.

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

Summary

The paleomagnetics lab was used this cruise to measure APC and Half APC section halves and discrete samples. A strong overprint like signal was observed at Sites U1476 and U1477 for many cores. This signal was not removed by step wise demagnetization and was visible in the data in the first two sections of many of the cores. Approximately 350 discrete cubes were collected from working half sections and measured with JR6 Spinner Magnetometer and Kappabridge KLY-4S. The Icefield MI5 tools were deployed at Sites U1474 for full APC cores. But due to the strong current, the tools failed downhole. At the scientist's request, we used the Flexit tools to orient cores at U1476, U1477, U1478, and U1479.

Issues

SRM

• In order to check the bore of the SRM for damage and debris, we ran a Go Pro camera through the SRM on the tray using Galil tools. There appeared to be an accumulation of dirt between the low field and degauss regions. The low field region was removed from the SRM and a thorough cleaning was completed.
• A high level of noise on the Z squid was noted during VRM noise monitoring tests. Heating the squids and repeating the noise measurements with the flux gate corrected the issue.
• The new touch screen monitor was installed at the SRM station.
• The scientists noted that for the cores that had what appeared to be a strong overprint, the inclination would not reverse. The inclination would stay at approximately 0 degrees. There was concern that something was wrong with the z-axis or that the trapped field had been lost, but flux gate measurements indicated the trapped field was still present. We were unable to identify the cause of this problem.
• We had a persistent problem with the Galil board on the SRM this expedition. There were two separate incidents:
  • While the scientists were measuring on the SRM, the software stated it had completed the sequence, but the core was still in the shield extension. The Galil board indicated an overcurrent error. The error was cleared, but the board had no power and was unresponsive to commands. The fuse in the power box for the Galil had blown. We replaced the fuse, but upon powering the system up the new fuse blew. We replaced the GALIL board and fuse again and the SRM began working again.
  • While using Galil tools to investigate a peak in the section data, the Galil board and fuse blew once again. The motor and the Galil board had to be replaced.

The problem was determined to be related to the coupling between the motor and the starboard side support for the sprocket that a pulls the core through the SRM. This coupling was pressed too tightly against the support and was causing the motor to draw too much current. The ETs adjusted the coupling and we saw no further issues with the Galil motion control on the SRM.

• The new SRM software and M-Drive motion control system were tested during the expedition with success.
• Electrical outlet drawings were completed during this expedition in preparation for the installation of the new SRM.

Icefield Orientation Tools-

• A gap was noted in the 1474E2H (tool 2043) survey. The time stamps read properly until 8:02:50 and then the next time stamp is 10:04:50. It is unclear if the tool stopped measuring for this time period or if the clock simply malfunctioned.
• The Agulhas current took a toll on all three Icefield tools. Tool 2052 (survey 1474F1H) returned to the drill floor with noticeable damage. We were unable to download the survey from 2052. When tool 2043 was retrieved from downhole (Survey U1474F14) we were also unable to download the data or contact the probe. The Palm gives a message stating that it is unable to contact the probe. In the past this message was given when battery power was too low. New batteries did not solve the communication problem. Figures 1-4 illustrate the damage noted on tool 2052.

Maggie's description:
As soon as I unpacked it I could see there was damage to both the tool and the brass connector piece (see attached photos). The brass connector piece was very difficult to pry from the slot in the tool and took one person to hold the tool while another gently tapped it out of the slot. The brass connector is also galled and there were brass flakes scattered near the threads and the spring. The tool proper is also galled in spots and the tool was not blinking when it was unpacked (a bad sign already). The Palm could not connect with the tool despite several battery changes. The batteries used inside the tool also showed some damage but still had good voltages according to Garrick. By the way it was also surprisingly difficult to remove the end of the tool where the batteries are inserted. Garrick has since polished that part to smooth out the galling there.
Figure 2- Image of wear on tool 2052. This damage was not present before the U1474F survey.
Figure 1- Brass flakes on the keyed end seal of tool 2052

Figure 3- Close up image of tool 2052 Figure 4- Keyed End piece damage







We attempted to use a DC power supply to power the tool and retrieve the data. The tool drew no power and showed no signs of turning on. Tools 2052 and 2043 were not deployed again. These tools will be sent to College Station at the end of the expedition.
As a note, the brass connections are still rather difficult to put together and take apart, even after some of the ET repair work.

• Figure 5- Broken wires at battery connection for Flex-it 0936
• Tool 2007 returned from survey U1474B1H still looking to be operational (light still flashing) but the data download failed twice. When new batteries were put into the tool, we recovered data but only for the early part of the survey. This tool seemed operational and was deployed at sites U1476 and U1477, but after further data analyses it was noted that the tool never gave an MTF value outside the range of 100 to 200 degrees. The overly consistent values were troubling and we opted to stop deploying tool 2007. Tool 2007 will be airfreighted back to College Station at the end of this expedition.
• Another issue we noticed was that the declinations after orientation correction appear to be 180 degrees off from expected. I contacted the Icefield tools vendor to inquire as to the tools functionality. They are currently looking at some of our data files to determine if there is an issue with the tools operation in the southern hemisphere. This is still an ongoing project.
• Battery connection on Flexit 0936 was repaired. The wire connections were broken just above the connector and the wires were shorting causing the batteries to heat up.
• Flex it tool 0937 was run at Sites U1476 - U1479.
• We were low on Flex it batteries at the start of this expedition. Garrick made two new battery packs using the wire hardware from our depleted battery packs and 3 SureFire Lithium premium 123A batteries for High-Drain devices (SF12-BB). These batteries are 3 volt and have a 10 year shelf life. The ship made battery packs were used successfully. If we intend to keep the Flexit tools operational, we should consider stocking these batteries. The ETs currently have enough batteries to make one more new battery pack.

JR6 Spinner Magnetometer

• Installed Rema6W 6.2.4 (odp format) software for JR6 to correct issue causing zeros in the data file
• JR6 1- Scientist noted issues when attempting a calibration. Found that the actuator rod was not moving to the UP position properly. The spinner was replaced with spinner 2. We removed the actuator rod and found what appeared to be silicon grease and dirt. The ETS used brasso and Never Dull to clean the rod and reassembled the spinner. The timing and motion worked properly.
• JR6 2 worked initially but during measurements the scientists noted an error with the holder correction. The actuator rod moved in the up and down motion, but would not spin. There appeared to be a broken wire leading to the turning mechanism. The ETS reconnected this wire and cleaned the actuator rod. The spinner was put back in storage after successful testing.
• Figure 6- Actuator from spinner magnetometer with corrosion and dirt build up.The ETs recommend we investigate purchasing set screws for the spinner actuator assembly and to monitor the actuators for corrosion. See Figure 6

• While cleaning the interior of the JR6 prior to the start of Exp 361 a lot of particulate matter was found. See Figure 7 and Figure 8. The material appears to be a mix of dirt, black plastic from the inside of the JR6 clam shell, and yellow foam. The foam appears to be from the vibration dampening gasket inside the spinner. This gasket is visible in both spinners. We are currently unable to determine if the gasket has always been visible or if the separation is a new development.

Figure 7- Close up image of particulate matter inside the JR6 spinner magnetometer

1Figure 8 - JR6 Spinner Magnetometer particulate matter. Arrow indicates the likely source of the yellow foam material.

Thermal Demagnetization Oven

• During Exp 360 the scientists and Paleomagnetics technician determined the oven switch had gone bad and preformed a temporary repair to the available switch. At the start of Exp 361 we replaced the switch with a new switch and stored the spare in the lab. The oven was tested, but was not used this expedition.

Cryomag readings

PHYSICAL PROPERTY LAB

MarGARET Hastedt, NICOLETTE LAWLER and Alexis ARMSTRONG

Summary

Expedition 361 saw relatively few issues with the lab's equipment. We had software upgrades on the WRMSL and STMSL, and a hardware upgrade with the new Cesium source for the GRA. Other than the tracks the PP lab was fairly quiet this expedition.

Individual Measurement Systems

velocity gantry

The Velocity Gantry system was occasionally used to measure the X axis velocities of split sections. The scientists declined to use the bayonets this cruise. They were happy with the velocities obtained on the WRMSL and only really used the calipers on the gantry when the sediment was too gassy and/or dry to produce velocities on the big track. The calipers were cleaned and couplant added as necessary.

moisture and density (MAD)

The MAD station ran without issue. We did not experience the database communication errors seen at the end of X360. The PP scientists only performed MAD tests on the first holes of our sites so relatively speaking it was lightly used this cruise (approximately 400 samples from over 4200 meters of recovery as of 3/21/16).
Fig 1: Ice chunk in the LaudaNote to us PP techs: Remember to periodically (twice/cruise) check the water level in the Lauda bath. It sits quietly on the shelf above and slightly to the right of the pycnometer and is very easy to forget. The water level was quite low (about 2/3 full) at the beginning of the expedition and a huge ice chunk had formed in the tank, see Fig. 1. Additional DI water was added to bring the fluid level back up which quickly melted the ice.
Issues: At the beginning of the cruise, samples were not being displayed in MADmax as a database table had been altered on Exp. 360. As a result MAD tests were not being created properly and thus would not appear in MADmax unless the user clicked on "show completed tests". Also, a single MAD vial was used for a sample but it didn't have a mass in the database. Both mix-ups were rectified by the developers.
Miscellaneous: One of the two MAD desiccator cabinets was retired and another was borrowed from the X-ray lab. The retired unit's latch was not sealing the cabinet properly and desiccant turned pink very quickly. Now both units have the same top-and-bottom latching mechanism and seal nicely. The ALOs are searching for a permanent replacement. The red felt inside the blue box of weights for the balances was removed as it was leaving more and more lint on them. The inside of the box was also cleaned to remove dirt etc.
Technical Service: Pycnometer cleaning and calibration were performed throughout the expedition. Lid O-rings were changed at the beginning of the expedition. The standard SPHERE_10 was measured as a calibration verification throughout the expedition per the usual SOP. Additionally, a data-mining study of pycnometer cell and reference volumes and SPHERE_10 calibration verifications over time (2010-2016) was created, the latter of which is included here for reference.
The graphical analysis of Pycnometer performance from August 2010 through March 2016 based on calibration verifications using the SPHERE_10 standards. Data from August 2013 to December 2014 was omitted as reports for these dates were not available on the ship. This will be added on shore post-cruise to complete the analysis. In addition 78 data points were excluded from this study as their values were extreme outliers (near zero and 20 or higher) that would obscure the higher resolution scale needed to best assess the range of interest. There is some drift in values during January 2012 which appears to be related to worn rubber seals as indicated by the Technical Report from X339. Since then values have been consistently within the allowable 1% error range for our cells. Over the six years of this study only 95 values, excluding outliers, have exceeded the acceptable threshold with 75% occurring in 2011 and a combined 13% in 2015 and 2016. Of these cells, Cell 1 has been the least consistent, and cell 6 the most consistent, even after accounting for the time cell 6 spent offline. Cumulatively the pycnometer has been within the 1% error range 95.6% of the time over the six years of this study.

shear strength station

The AVS system was not used during the expedition. Garrick reported that the fan on the Giesa controller is making more and more noise and is probably about shot. We turned everything off for the duration of the cruise.

WHOLE ROUND multi-sensor loggerS

Expedition 361 debuted the new IMS software for both the WRMSL and STMSL. Additional testing and debugging were done during the first transit. The new software brings these two tracks into compliance with the common coding structure in place on the SHIL and SHMSL.
Thanks to the effort of the staff, numerous issues were identified and fixed early on. The program has been operating for the last half of the expedition without changes and is very stable. However, there are a number of known issues that need to be addressed in tie-up that are listed at the end of this section. The Quick Start and User guides are under development and should be completed by the end of the expedition. Copies in their latest revision will be left on the desktop of both systems.
In addition to the software upgrades, both tracks were converted to use the new M-Drive servo motor systems. The current interface boards will see one more revision by the end of the tie-up period which will allow the program to sense and recover from an emergency stop event.
Outstanding Issues:

• Using the Standard editor can corrupt the configuration file. Does not happen every time. The cause needs further investigation and remediation.
• The emergency stop while disabling motion control does not cause an error condition in the software. Measurements continue as thought the track is still running. A new version of the interface board will correct this issue.
• Some misinformation on the setup screens.
• MS Setup needs a full revision. The MS correction process need to be revised to accommodate both paleomagnetics studies and correlation needs. Information left from the MS probe operation on the SHMSL are not needed on the WRMSL/STMSL version… can be confusing.
• Need to remount the top-of-section switch so that mud cannot cover the sensor. Also, mounting needs to avoid the situation where the beam passes thru the center. Clear objects can actually act as lenses and increase the signal to the sensor rather than the other way around. Lensing occurs when the beam is shines thru the exact center. Moving it to the side of center solves the issue.
• The PWL calibration interface is too complicated. Easy to make mistakes. Also, should implement the telescope P-wave standard.
• Issue with MS communication that cause a dropped value every couple of 100 measurements. This an intermittent issues that has been seen on both tracks.

Special track multi-sensor logger (stmsl)

The STMSL was heavily used this cruise on un-equilibrated cores. Essentially it ran every core that the WRMSL did and usually at the same offsets. Bill and the ETs adjusted the home and limit switch positions ensuring that the two whole-round tracks were as identical as humanly possible so that measurement offsets/computed depths in the data files would closely match.
The STMSL magnetic susceptibility has the frequency-adjusted loop. The STMSL and WRMSL MS loops were cross-calibrated using the same MS check standard mounted in a piece of liner with a hard stop glued to the outside. The check standard was inserted identically in both loops, tested repeatedly and the correction factor calculated for the software. This was an effort to make the instrument unit output of the two loops agree more closely, which helps stratigraphic correlators if/when the two tracks are run simultaneously in high-output ("half-and-half") mode as it substantially reduces the data offsets seen on previous expeditions. Half-and-half mode refers to the method of placing sections 1,3 and 5 of a core on one track and sections 2,4,6 and 7 on the other while running both tracks at the same time.

Whole Round Multi-Sensor Logger (WRMSl)

The WRMSL ran successfully for the duration of the expedition.

P-Wave Logger:

Caliper: Came onboard and found the slide mechanism locked up. To get the system to close-open we had to set the Exlar to 5 amps which is the maximum force setting. This is unsafe. On the 6 day transit to the first site, we completely dismantled system. One shaft had to be hammered out of the bronze bearing. All of the shafts and bearing where were polished. The one bearing that was stuck had to be drilled out to open the tolerances so it would slide. The bearings where sonicated to remove old oil and grit. Afterwards they were dried and re-saturated in oil. The system was assembled and aligned. With the rebuild it now would move with 1 amp of force.
During the expedition we noticed a slight sticking behavior when either an open or close started. Looking closer we noticed that the caliper plates would cock as the pressed against the stops or core. With the two caliper out of parallel the connecting LVDT was bowing. Below is an exaggerated illustration. The sticking behavior was the actuator overcoming the bind.
This is causing several problems:

• The binding is accelerating the bearing wear and the binding will become worse.
• When one side of the caliper comes free before the other, the core is physically shoved to one before dropping back into the track. This can cause errors in the MS and GRA measurements.
• The distance measured by the LVDT no longer represents the distance between the transducer and thus erroneous velocity are calculated.

The current design allows for too much leverage between the closing force and the contact point on the core. Ideally the force should be co-axial with the transducer pushing directly from behind. All of the force is applied to the cap retaining ring and this why we have thread failures.
The next issue is calibration. If you measure the standard with large force (cocking the plates) and then measure the cores a lighter pressure, you can cause an error of more than 80 m/s. This can be demonstrated with a water core using the PWL utility after a calibration. If care is taken to keep the same contact force during calibration as with a measurement, we can achieve nearly perfect temperature corrected water velocity values. Unfortunately, this means you cannot adjust contact pressure for XCB and rotary cores.
The system is so worn out you can rock the caliper plates with just hand pressure. It is time for a replacement.
Signal Processing: The first derivative method for picking the first arrival implemented in the previous MSL was revised to improve noise suppression. A draft method note has been appended to this report.

GRA

Fig. 3: Illustration of the dual-collimated source and its shutter positions, excerpted from the 2014 GeoTek MSCL manual, p. 44.Received a new Cesium source for the GRA at port call. This new source has a shutter mechanism (fig. 3 and 3a) identical to the one currently on the STMSL.
Fig. 3a: Photo of the operating lever seated on the detent. When correctly seated you will feel the detent settle into the indentation on the barCare must be taken to ensure that the shutter is fully open. We use the 5 mm opening for our tracks. The source is tightly collimated and counts will be substantially lower if the shutter arm is not properly seated on top of the detent (which looks like a small conical stub). The following are some screen shots from the GRA utility in the new IMS software illustrating this issue.
Fig. 4a: GRA spectra with the shutter fully closed. Amplitude of peak is very low (~5), spectrum is 'hairy' and counts per second in the region of interest are < 5.
Fig. 4c: GRA spectrum with the collimator fully open and seated on the detent. This is the real deal: very high amplitude (> 1100) and ROI counts per second well over 50,000. Fig. 4b: GRA spectrum with the 5 mm collimator partially open and the operating lever up against but not seated on the detent. Nice high (~300) amplitude clean peak; ROI counts are up to ~14000. Looks pretty good, doesn't it?

Section half image logger (shil)

The SHIL saw normal sediment-core usage this expedition. As with the whole-round tracks and SRM this cruise MUT problems were common; see Developer's report for details. There was a brief time period where the lighting was adjusted to concentrate on the surface of the cores for testing RGB values coming from our very neutral-gray cores (material from our first two sites, again for the benefit of the correlators), but the effort was quickly abandoned and the lights returned to their original configuration. For further details please see the Imaging Specialist's report.
The previous expedition reported numerous and regular application crashes. We only experienced a couple during the expedition. Our theory is that the crashes are related to MUT uploading numerous images making demands on Window's memory manager at the same time the SHIL application is demanding memory access …SHIL loses! We have no hard evidence that this is happening, strictly anecdotal but since the release of MUT 15.0 (loads only one file at a time) we have had no reported crashes.

section half multi-sensor logger (SHMSL)

The SHMSL ran successfully throughout the expedition, with MS point and color spectrometry measurements taken on archive section halves. On occasion the scientists decided to skip MSPOINT measurements in order to save time for high-resolution (1 cm) color reflectance. The halogen bulbs were changed at the beginning and midway through the expedition.
During the transit to the first site, the following changes and maintenance were performed:

• Removed all of the 3D laser hardware (hopefully someday it will be implemented)
• Replaced on of the two halogen light sources for the RSC measurement, with a Blu Loop illuminator. The Blu Loop is a combination of blue leds and fluorescent doping that produces a spectral output designed to fill in the blue side of visible spectrum when used in combination with a halogen light source. It is hoped that this will address issues with Goethite- Hedenbergite spectral studies.
• Replaced the existing power supply with a modular Excelsys power supply
• Added a USB hub
• Cleaned up wiring

Natural Gamma Radiation (NGR)

• The NGR ran nearly constantly with no major problems. We have started a study of the long-term performance of the instrument since it was installed in 2009. We're investigating calibrations (slopes, intercepts, and energy channel selections), background sensitivity to latitude, and understanding the equations involved in the data reduction among other pertinent details. Analysis will continue back in the office.
• Excessive core lengths can be checked by opening LORE NGR data in Excel and using conditional formatting to highlight readings below 1CPS. Cores entered with lengths too long will often have negative or <1 CPS readings. If any of these extremely low values appear, check the Section Summary report to see if their section lengths were entered too long on the NGR at measurement time.
• Energy calibration checks were performed on 2/10, 2/20-22, 3/8, 3/17 and 3/24/16.

Issues: During the cruise's second energy calibration check detector 7 began to display unusually high (up to 70%) dead-times. Normal dead time percentages range on average in the 4.5-6.5% range. This immediately brought to mind the problems seen with detector 3 on Exp. 341 and 345. However, whatever was troubling detector 7 disappeared and has not been seen since. We have no explanation for this phenomenon and why only a single detector had problems.

Thermal conductivity

In port call thermcon worked normally on unregulated power, however, once the transit started we could no longer get any results on macor. The Teka was switched to its UPS (unplugged and running on battery for each measurement series) for the first three sites. After doing additional tests mid-cruise using both pucks and needles on macor standards, the Teka was shown to be able to produce correct values when run on both regulated and unregulated power. Measurements were subsequently performed using regulated power on actual cores with good results. Changes in shipboard power and SIEM operating systems is hypothesized as the reasoning behind the sudden change in usable power.
Issues: The 'Root Name' known bug occurred once in a while again this cruise. Manual file edits were the quick solution to the problem. Also, Garrick adjusted the gas struts on the 'coffin' so that the lid will stay wide open for loading. P-Wave Logger (PWL)
EQUIPMENT
The PWL system consists of two 1" diameter, 0.5MHz piezoelectric transducers from Olympus (model M2008) with the following characteristics:

• Central Frequency: 0.48 MHz
• Peak Frequency: 0.07 MHz
• -6DB Bandwidth: 75.42%

Both transducers are protected by a stainless steel delay-line cap. Propylene Glycol or Glycerin is used as a couplant between the piezoelectric element and cap and should be renewed weekly.
The transducers are driven by an Olympus Pulser-Receiver (model 5077PR). Vendor's description:
The Model 5077PR provides square wave excitation with a fast pulse rise and fall time. The pulse voltage and pulse width are adjusted directly to provide precise control over pulse shape. By tuning the period (pulse width) of the square wave to half that of the transducer center frequency, pulse energy to the transducer at its natural resonant frequency is increased.
For P-Wave Logger we set the Pulser-Receiver to produce a -200V square wave for 1µsec (0.5MHz), at 200 pulses per second. The return signal is amplified as necessary by the pulser to overcome signal attenuation (-50 to 50dB).
A single linear variable-displacement transducer (LVDT) measures the distance between the transducers as a voltage output. The thickness of the core liner is doubled and then subtracted from the LVDT value (converted to mm) to give the thickness of the core material within the liner.
Signal digitization is performed by a National Instruments high speed 8-bit digitizer (model NI-USB 5133). The digitizer has two channels, Channel A is connected to the Pulser-Receiver to capture the waveform and Channel B to the LVDT to capture the voltage changes related to the distance between the transducers. Both channels capture data at a 100MS/ sec (Δt = 50ns) and are triggered by the timing signal from the pulser-receiver. Channel A's range is set to +/- 1v and Channel B is set to +/-5v.
The transducers are mounted in a caliper system which is driven by a Tritex rotary-liner actuator (model TLM20). Acoustic coupling to the core liner and the material inside is enhanced by a water drip system. Both the actuator and water pump are controlled by the IMS track software which coordinates the closing and opening of the transducers as the core is moved from one measurement position to the next. Spring loading of the caliper ensures a consistent contact pressure; although, the actuator can be set to compress the liner so that contact is made between the liner and the material within.
SIGNAL PROCESSING
Figure 2 on the following page summarizes the following signal processing discussion.
Figure 1Acquisition and Ensemble Averaging: The received waveform is digitized at 10 nsec intervals and collects a record 60 µsec long. The first 10 µsec of the waveform is replaced with zeros to remove a large spike that occurs at the beginning of the outgoing pulse. We believe that electrical "cross-talk" within the pulser-receiver to be the source of this noise.
A Butterworth Bandpass filter is then applied to the waveform to reject frequencies less than 0.4MHz and above 1.0 MHZ. This bandpass-filtered waveform is then stacked, summed and averaged (ensemble averaging). The size of the stack is a value between 10 and 100 as selected by the user.
Even with this initial filtering and ensemble averaging, the resulting signal can still contain significant noise generated by the shipboard environment. Figure 1 is typical of the signal quality.
Picking the 1^st Arrival: Past attempts to use a cross-correlation method (popular in seismic analysis) have not been successfully applied to our data. Coefficients developed for one type of lithology would fail when the lithology changes. Therefore, we still depend on a threshold crossing process to determine first arrival time. The weakness of this method is that any high amplitude noise can cause a false pick.
To increase the likelihood of a correct pick, the P-wave Logger software on the Whole Round Multi-Sensor Track (WRMSL) uses a series of mathematical and data manipulation techniques to suppress the noise relative to the peak of the first arrival. Another goal is to eliminate the constant adjustment of the threshold value as the amplitude of the waveform changes due to variation in signal attenuation along the core. The P-wave Logger is automated system and constant supervision and adjustment is not practical.
Signal to Noise Ratio (SNR) Enhancement: Methods employed are based in part on Dr. Tom O'Haver's 2006 publication: A Pragmatic Introduction to Signal Processing (http://terpconnect.umd.edu/~toh/spectrum/IntroToSignalProcessing.pdf).
The ensemble averaging done at the acquisition stage is effective at eliminating nearly all of the random noise. Unfortunately, our signals contain a great deal of systematic environmental noise that cannot be fully eliminated by shielding signal cables. To suppress this noise, we need to exploit small differences between the noise and the acoustic pulse. The parameters used in the smoothing operators were developed empirically measuring a variety of materials and by degrading the signal by attenuation at the pulser-receiver. Time was limited on Expedition 361 to select the best smoothing operators and their parameters. Further experimentation is needed to improve the process and validate that it will work for all possible lithologies recovered by IODP.
Figure 2
The SNR enhancement process consists of 3 steps: 1) smoothing, 2) 1^st derivative, and 3) smoothing. The first smoothing step passes the waveform through a Savitzky-Golay filter that applies a polynomial least square fit step-wise through the data (similar to a running average). Experimentation shows that using a 6th order polynomial across a 126 data points will reduce high-amplitude, high-frequency noise while retaining the shape of the acoustic pulse.
After the first smoothing operation, we then take the 1st derivative (central-difference) which suppresses the low-frequency noise. The downside to the differentiation is that the process adds back in high-frequency noise. This why we run a second smoothing step. A FIR operation is used in the second smoothing pass. The FIR filter coefficients were calculated using LabVIEW tools.
Figure 3The Figure 3, shows the waveform (as absolute values) before and after the 3 step process and illustrates the significant noise suppression that was achieved. Attempting to find the first arrival on the un-processed data would have failed because the amplitude of the noise is greater than of the first arrivals peak.
Normalization: At this point in the process, a copy of the waveform is normalized so that the waveform is scaled between the values of -1 and 1. A second copy of the processed waveform is converted to its absolute value and then normalized with the waveform scaled between values of 0 and 1. This normalization is critical to making the threshold picking process indifferent to either amplification or attenuation of the signal. Experience has shown that the threshold value needs little adjustment once chosen unless there is a significant lithology change.
Figure 4: The left-hand graph shows the threshold (Horizontal cursor) crossing the first peak of the acoustic pulse and the 1^st zero-crossing (vertical cursor). After correcting the time, the right-hand graph shows the pick on the original stacked waveform.1^st Arrival Time: The threshold crossing is performed on the absolute copy of the waveform. The crossing time is then used as the starting point to find the first zero-crossing in the derivative waveform. From this time value, we subtract 1.5µ to account for ¼ wavelength phase shift caused by the 1^st derivative operation, and ½ wavelength correction back to the first arrival. See Figure 4.
Waveform Data: The process described above greatly distorts the original waveform. Any time shifts artificially induced are eliminated by the P-wave calibration and rolled into the system time delay value. The waveform that has been band-pass filtered and ensemble averaged is saved for post-cruise studies and the processed waveforms are discarded after the 1^st arrival.

Summary

Expedition 361 has been a high recovery, and 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.
No major issues with software/programs occurred. The exposure/white balance was checked between each site and adjusted as needed.

Equipment & Software Performance Summary

• 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 whole round sample check. These all worked fine as expected.
• A bulb was replaced in the core lab stereoscope light source.

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.

Additional duties

CHEMISTRY LAB TECHNICIANS REPORT

LISA BRANDT & RACHAEL GRAY

As of 1800 March 25

Instrument Status

|Segment #|Force (lbs)|Dwell time (min:sec)|

Ampulator

• The Adelphi ampoule sealer was used, with no issues to report. We requested that several "BBQ" style lighters be purchased at port call, as part of the shore shopping list. Lighters cannot be sent in the shipment. We currently light the ampule sealer with a propane torch, which is overkill.

Balances

• No issues to report for the Cahn & Mettler balances.

Carver Presses

• The Carver presses received a lot of attention this expedition. For hilarity's sake, we have renamed the presses Brad, Bill, and Roy. Bill the middle pump worked fine all expedition. Brad and Roy had their motorpak pumps replaced. The new pumps were filled with oil, and also had their oil levels checked after the site completed. They were then topped up with oil. We also changed the preset speed settings, so that the pump reached its initial setting more quickly, without overshooting the setting. We also created an automated program for squeezing that worked for our whole rounds, which were described as "silty margin sediments." The program might not work as well for other lithologies. We have the initial force setting of 3000 lbs for one second, in order to overcome the pump speed issues. The pump speeds can be changed via following the procedures in the Carver publication, Carver NE Press Maintenance and Calibration screens. I put a copy of this in the Carver Presses binder.

Cary Spectrophotometer

• The Cary was used to analyze phosphate, with no issues to report. We received the new auto-sampler for the Cary, but did not install it. It is currently located on the upper tween landing. We had an issue with the flow cell. The pump was not dispensing solution. We took all the tubing and connections off, and blew air through them to remove any potential clogs. I was not able to get any air or solutions through the flow cell. I replaced the cell.

CHNS

• Total carbon and nitrogen were measured on the EA. There were no issues with the unit.

Coulometer

• The coulometer was used, no issues to report.

Freeze-drier

• The oil was changed mid-expedition. The seal to the cooling chamber was replaced at the start of the expedition. We requisitioned a new vacuum hose, to replace the vacuum pump-condenser connection, as Garrick has been requesting this.

Fume hoods

• All chem lab fume hoods are back in service after a fan was repaired (by SIEM) early in the expedition. No other issues to report.

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.
• Hydrogen generators
• No issues with the hydrogen generators.

IC

• The IC continued to have issues with inconsistent uptake by the auto-sampler. The workaround we have found is to have the auto-sampler pump DI water (by manually pointing the needle to the "Special beaker" full of water and manually starting the auto-sampler peristaltic pump) and disconnect the tubing after the membrane filter, then let the water drip through into a waste beaker for a few minutes.
• Since the lab working group decided that we no longer need to upload PDF chromatograms, IC results can now be uploaded by dropping the determination reports (Excel file only) into MUT's upload directory in large batches, instead of one at a time.

ICP

• The ICP was used to measure minor and major elements on the IW samples, as well as to analyze sediment. We replaced several parts at the beginning of the expedition: fan filter on right side of ICP, air knife, purge gas tube, and welder's glass on spray chamber door. Welder's glass has held up well, with no cracking. No instrumental issues to report.

salinity

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

SRA

• The SRA was disconnected and moved to the cold room to make room for a third-party IC. It is now back in its regular location, but has not been hooked up or tested.

Pipettors

• No issues to report with any of the pipettors. All pipettors are going to be shipped to shore from Cape Town to be calibrated, with the exception of three to be left on board for training/general use during tie-up.

alkalinity

• No issues to report.

Chloride

• No issues to report.

Water system

• No issues to report.

XRD & ICP SAMPLE PREP LABS

Seth Frank

Summary

A high recovery sediment expedition that saw little to no samples processed through this lab and a plethora of unexpected transit time. All extra time was used for cross training techs in both this lab, thin section and physical properties. All instruments and machines in the X-ray lab worked without incident, an updated lab guide was written, and an X-ray lab cookbook started for future techs in this position.
Total Samples

• XRD: 15
• ICP: 100
• MBIO: 0

Equipment Status

X-ray Diffractometer

• A full QAQC at the beginning of the expedition showed no need for adjustment. Subsequent runs of the NIST1976 throughout the expedition also showed no need for any adjustment. Water flow rate from the Haskris began at 6.40 l/min and at the end of the expedition was 6.34 L/min.
• X-ray tube conditioning should still be recorded and monitored for any changes.
• During tube conditioning, a high-pitched, faint sound (squeaking perhaps?) heard from what I can only assume is the D4. Looked for source and found nothing. Tube conditioned fine, water flow range good, no errors or faults, sound was regular for about a minute, then became much less regular as time went on.
• Wrote a new detailed diffraction guide. This was used to train both Ben Daniel and Nicolette Lawler, both of whom spent a considerable amount of time training in the X-ray lab during the transit times and in otherwise free time.
• My recommendation for tie up is to inspect the x-ray tube and cooling water hoses and backflush the system to clean it and sonicate and clean the spray nozzle and filter head in the tube housing.

ICP Prep

• Flux fusion sediment ICP was performed this cruise with good results. It is my recommendation that 10 of the platinum crucibles should be sent off to get re-cast, these have been set aside for the time being. Those 10 have been packaged up in the AF to be sent back to IODP.
• No LOI was done this cruise. Beads were made in only 13 of the crucibles that exhibited no scores, dents or folded top lips and they were made without issue.
• Mettler Balance: The unknown balance now regularly stops working and displays the error "Program memory defect. Contact Service Technician" at least once a day. I kept the balances off for the entirety of the cruise.

THIN SECTION LAB

problems encountered

• Led Seth Frank through the process of receiving orders, making thin sections, and imputing finished product into Sample Master correctly. Provided advice and oversight as he attempted to make a set of 6 on his own. Gave him basic instruction in operation of all equipment as well as several techniques and tricks that I have learned over the past year.
• WG2 polishing head seemed to be rotating slower than normal. Would not respond to commands when first turned on, removed electronic connection between WG2/PM5, cleaned and reconnected. Worked after this.
• Had some issues with consistent vacuum pressure on the LP50 Vacuum adapter hose heads. Took apart the white vacuum adapter heads for cleaning. Sonicated and swapped a broken coupling sleeve out with a used but good sleeve in the LP50 drawer. Kept broken sleeve. Might be able to be fixed with glue, but I have not done this.

Miscellaneous

• Routine equipment maintenance and cleaning was done as needed.

So long TS lab, it has been a trip.

UNDERWAY GEOPHYSICS & FANTAIL REPORT

WILLIAM MILLS

Underway Lab

Bathymetry

• Bathymetry was collect on all transits and sites. No issues to report.
• Experimenting with Threshold setting, it appears that setting the value to highest has the best chance of locking onto the bottom.

MAGNETOMETER

• Data was collect on all major transits;
• When retrieved the magnetometer after the transit up the Mozambique Channel, we found that two of the three stabilizing fins where gone. We found replacement in the lab and have ordered two more spares. It looked like fishing line pulled them off.
• Removed the Chinese fingers from the line after discussing the need with Roy. We agree that it is better for the cable to take the stress around the circumference of the drum instead at a single point.
• Re-repaired some of the jacket patches that where coming undone.
• Wrapped the cable with bull dog table and scotch coat where it sets in the level wind when fully deployed. Wear protection.

GYRO

Where's the gyro?! Apparently on the previous expedition the MCS lifted the Blackbox Serial server (per their tech report) and installed it on the SubC DVR. Hopefully they got Roy's permission first.
While it is true that we have set WinFrog to use the GPS baseline between our two GPS antennae for heading information, but if one of the GPS should fail, the gyro becomes our only source for heading information. Without it we have no navigation. DON'T TOUCH!

Fantail

Deck Crane

• Was serviced and exercised. The last extension is jammed (rusted). We need to think about doing some major preventive maintenance soon.

Port Magnetometer Winch CONTROL ALIGNMENT

• !worddavbfb18112b65fca66cc23bfc2f55fff7d.png|height=245,width=245!If there is a cable on the drum, then remove it from the level wind and wrap it tightly around the drum. Use a line to secure onto itself so that if the drum turns in any direction it cannot damage the cable.
• Open the access hatch to the hydraulic motor and you will the control adjustment near the top.
• Loosen the nuts (orange arrows)
• Adjust the bolts (blue arrows) so that they rotate the control shaft (red arrow) to the hydraulic motor so that the drum is in the neutral (not turning) position. You'll need to turn the drum on to verify that you have done it correctly. If you are careful you make the adjustments with the drum on. Just make sure no one can get hurt or damage the cable.
• !worddavbd4a1faf4cc84204d4ac54bedcf3ebd6.png|height=242,width=242!Once you have found the neutral position, you need to check for play in the control handle. If you can move it back and forth, and the drum does not move, you have compressed the spring too much.
• Evenly back of the bolts (blue arrows) until the spring, on both sides touches the bolt (yellow arrow) attached to the control shaft.
• When done right, there will be no play in the control and if you pull it in any direction and let go, the control will center and the drum will stop turning.
• On the outside, you can adjust the angle of the control's handle my loosening the handle and the set screw (180®), and then moving it into the correct position. Tighten the set screw and handle.
• Don't forget to tighten the nuts (orange arrows)

Level wInd

If I had a dollar for every time I was told that the level wind is fix…
On our first deployment, the level drove straight for the portside. Only by jamming down on the manual override where we able to control level wind position. After the ET's, using Juries' repair instruction, failed to get them system working, I ask them to disconnect the fleet arm control and make it manual only system. I was tired of fighting the D### Thing!
It was working without issue until we deployed it on our last transit. It started off fine and then the system drove at full speed until end-of-travel rod hit the chain guard. Made a very serious dent! Randy could not over-ride it with the manual controls and it was not stopped by the end-of-travel proximity sensor. Before we shut down the power it made two popping sounds and died.
The ET's post-mortem report found two blown fuses and two dead SCRs in the DC motor control. The DC motor appears to be fine. Fuses we have on board and the two SCR are on order. I plan to go talk to the folks at Dynaco to see if they made any upgrades to this system. At least we can upgrade the motor controller. The one in use is no longer being made.
By the way, we don't know if the damaged components caused the run-away or are the result of the system running into the stop. There is a good chance that there is more damage to be found.
G-man attached a bolt to the level winds acme screw and we were able to use a hand drill to position the level wind when we retrieved the magnetometer. It was left attached.

ET REPORT

GARRICK VAN RENSBURG & RANDY GJESVOLD

CORE DECK

DHML:

• Tested and prepped APCT-3 Tools number 7 and 9. Ran Tool 7 at site U1474 on Cores 07 and 10.
• Built battery packs for the Flexit orientation tools;
• All three Icefield tools where damaged by current induced drill string vibration and have been returned to CS for repair;
• Assembled two temporary core racks in down hole lab for overflow core;

BAT TRACK (SHIl 2)

• The track installed on the previous expedition as a 2^nd SHIL, was inverted and hung above the end of the SHMSL. Now referred to as the BAT track. The plans are still in the work but the ideal is to turn this track into a general purpose track that can set up as a 2^nd SHIL or other use for other measurements without disassembly of the SHMSL. An M-Dive motor was installed on this track.

SHIL notes:

• The SHIL does not use the TOC, END and CAP inputs.
• There is only one Emergency switch on this track, the second Emergency input must be "shorted" the use the M-Drive controller.

!worddave2d912f8f8574cb8c4c0966f40c02d26.png|height=159,width=222!WRMSL notes:

1. The WRMSL M-Drive uses all of the I/O's except for the CAP input.
2. There are two Emergency inputs to this M-Drive unit.
3. The Fiber Optic cable was re enforced at the mounts to ensure the beams stay constant on the WRMSL and the Fast Track. Flexing the cable could cause false indication and interrupt the track's program.

SHMSL notes:

1. The SHMSL M-Drive uses all of the I/O's except for the CAP input.
2. There are two Emergency inputs to this M-Drive unit.
3. The Fiber Optic cable was re enforced at the mounts to ensure the beams stay constant on the WRMSL and the Fast Track. Flexing the cable could cause false indication and interrupt the track's program.

Fiber switches on the WRMSL and STMSL tracks:

We used this opportunity to secure the fiber connectors with set screws as we noticed fluctuations in the readings if the fiber cables were moved. In addition, we used clear tape to secure the fiber cable to the support as this assisted with signal stability.
Please note, the laser beam should not project through the center of the "water core" as this would result in amplification of the light source and not trigger the switch properly. So, make sure the beam is off center. Currently the "trigger" value is set 200 points below the actual receive value. We have noted the normal receive levels.
If the light intensity levels seem low, then make sure that the receive connector is clean.

Tape and nut added to prevent wobbling and false triggers PHIDGET ACCESSORIES on the WRMSL track:

Water pump control signalsMS loop core detector (distance)Room temperature and humidity sensorsWater pump relayRelay powerTemperature and humidity inputs.USB control to WRMSL computerA Phidget 8/8/8 interface was added to the WRMSL system and controlled via USB cable. From this hub we can control a relay that will turn the PWL pump On/Off, measure the ambient room temperature and humidity and detect the presence of a core in the MS loop. In addition, via another USB connection we have an IR sensor that measures the surface temperature of the core. Except for the pump control, all of the other sensors are experimental.
Pump control: The ON command is sent anytime a measurement starts and the OFF command is only sent when the program closes. The user can still manually override by clicking the on/off button on the pump.
Pump priming and tubing: After reading the manual, we discovered that the pump can be primed by holding the on/off button down for 1 second. The pump will run at high speed until you remove let the button go.
The correct tubbing material has been ordered for the pump. The rubber hose is not what's recommended by the manufacturer.

SHMSL

• Removed the 2^nd halogen light from the SHMSL and replaced with a Blu Loop led light source. The purpose of adding this light is to provide a bluer illuminator of the sample.
• The new Blu Loop light ocean optic's unit was installed on the SHMSL. This light source do not have a shutter control function. Please note that the Blu Loop light is a 6Vdc instrument and not the 24V used by the Halogen light source. CAUTION: They both have the same connector!
• Both the Blu Loop and the Halogen units are switched on and off via the relay Phidget.
• Removed redundant wiring and the old power system from the SHMSL, re installed an Excelsys power supply system.
• Removed all of the 3D laser hardware
• Added a USB hub;
• New prototype mounted was tried this expedition for the integration sphere. Worked well after a few design changes. New mounts are being fabricate in CS for both the integration sphere and MS probe.

M-Drive

• During the commissioning phase of the WRMSL, M-drive motor serial number MDI3CRL23C7-EQ 172130445 V3.014 appeared to be faulty. It was decided to replace this motor and perform tests at a later stage.
• During expedition 361 we had the opportunity to upgrade a few existing M-Drive V3.2 to the new V4.0 M-Drive system. The main reasons for this was to move away from a two board system where the control and power supply was separate and with opto isolating IC to a single board design. The v4.0 also does not need the 75Vdc to 12Vdc and 5Vdc converter as V4.0 M-Drive uses a 50Volt DC power supply. The tracks that were upgraded during this expedition was the SHIL, WRMSL and the SHMSL.

M-Drive Design Issues

During the commissioning phase of the M-Drive v4.0 we discovered some design flaws:

1. The led indicators on the board were designed to light when the switches closed assuming a NC state but to make the switches fail safe, they are configured as NO (active low). This meant the leds stayed lit until the switch was engaged and then off. Opposite to what is needed. A 220 Ohm resistor was added to keep the leds dim until the switch is engage. Unfortunately, this meant that the LED's are constantly in the ON state when not active and in the OFF state when the input is active. In the v5.0 design the led and switch states will be configurable via jumpers.
2. The second problem, although not a design problem but an easy oversight during installation is the +15Vdc on the communication cabling that could be connected directly to the GND of the M-Drive motor. This happened during the SHIL installation and we lost the M-Drive motor, three limit switches and the USB485 to USB converter. In the v5.0 design we have opted for a 6 wire connection that requires the technician wire both the GND and the supply.

New components and the v5.0 boards have been ordered and will be assembled during the tie-up period. By the end of this time the following tracks will use the v5.0 M-Drive: SRM, SHIL, SHMSL, WRMSL, STMSL and BAT.

Mag Lab

• The motor came loose and spun, damaging the power wires.As the worm gear was found to be sticky. No lubrication was added to the worm gear. Primary JR-6A Spinner Magnetometer ceased to spin, we found the rotation motor to be loose. The loose motor turning broke the supply wire to the motor and caused a loose pin on one of the connectors, these were repaired
• Secondary JR-6A Spinner Magnetometer actuator rod was moving too slowly and was gummed up. This was cleaned and tested.

• Binding hereThe Galil motor controller for the SRM ceased to function. During troubleshooting it was found that the Galil amplifier was dead and there was a blown fuse in the power supply We noticed the following:
  • Signs of heat damage to the motor's power plug where connects to the amplifier.
  • Servo motor became very hot running normal loads.
• Replacing the servo motor and amplifier got the system running but then a week later it failed with the same symptoms. On closer inspection we found that the coupling between the reduction gear box shaft and the drive sprocket shaft, had shifted inward and was binding on the inner support for the drive sprocket. After adjusting its position so that it would turn freely, the motor runs warm and no further failures have occurred.

FO'C'SEL DECK

The plastic support between the valve body and the actuator mount was sheared apart.LN2 Gen:

The Chill Water cooling system was re built and the controller with a new 3-way valve system was installed. When the old actuator was removed we found the plastic support (that screws into the valve body and provides a mounting point for actuator) had sheared apart. The installation was missing a bracket that prevents the torque from spinning the actuator. Not sure if this was the cause of previous problem but certainly could have interfered with either opening or closing the value.
Both the actuator and valve were inspected and fount to be in good working order other than the issues described above. The flow restriction diaphragm in the new and old 3-valve are quite different. The new valve was ordered as 1 gpm. Not sure what the old valve gpm rating was, but it was significantly higher. The LN2 generator seems to be happy with the 1 gpm flow. The original brass manifold was disassembled and cleaned. Both the flow control and high pressure by-pass valves where gummed up with debris. Cleaning restored their functionality.
A horizontal bar of T-slot was anchored to the LN2 frame. From this, several vertical T-slot bars where attached that formed the frame work for the manifold. After a discussion with the Chief Engineer, we decided to leave out the high-pressure by-pass valve. As a closed loop system the chill water loop cannot have pressure spikes as seen with a city water supply. As shown in the photo below, we rebuilt the manifold using the SS high pressure fitting from UW lab. Although this is was extreme over kill to use these parts, the long pipe nipples provided secure point to mount the manifold.

Caver Presses

• Replaced the Autopak pumps on the forward and aft Carver Presses, "Brad and Roy".
• During operation the new pumps would not maintain pressure, we replaced the jack on the aft most pump "Brad". The problem remained, we then used a temporary manual Carver Press on the floor of the chem lab to help speed up the squeezing process. After re setting the automatic programs and changing the pump speeds the pumps worked fine on harder sediments. But at low pressure and soft sediments the pumps still have problems maintaining pressure. We also did oil "top-ups" on Brad and Roy.

Fantail

• VSP: Air gun cluster was assembled but never used.
• Deck Crane: The crane was greased, dry slide applied to the cable and exercised. Found that the second extension wouldn't extend out. It appears to be corroded in place. Will address during the stand down.
• Starboard Winch: The winch was greased, cleaned and exercised
• Port Winch: The winch was cleaned, greased, had dry slide applied to the level wind shafts and exercised. The winch control was adjusted so that it will stop in neutral (see Underway Teach Report). Designing a cage for the forward end of the winch to protect personnel. To be built and CS and may be on board by X362
• Port Winch Level Wind: During our first deployment, the level wind drove straight for the portside. Only by jamming down on the manual override where we able to control level wind position. Following Juries' repair instruction the issue seemed to resolved but returned during the next deployment. Per the Lab Officer's request, we disabled the fleet arm leaving only the manual push button to control the level wind's position.
• On our last deployment the system drove at full speed until end-of-travel rod hit the chain guard. It would not respond to manual controls and before the power was cut, the follower hit the end (ignoring the limit switch) and then made two popping sounds and died.

Suspect Component. Replacement Ordered.Upon inspection we found two blown fuses and a dead SCRs in the DC motor control. The DC motor appears to be fine. Fuses we have on board and the two SCR are on order. Bill Mills will talk to Dynaco about upgrading the system.
A bolt has been attached to the level wind's acme screw and can used with a hand drill to position the level wind manually.

Miscellaneous Repairs

• The Core Lab vacuum cleaner motor ceased to function, during troubleshooting we found the fusible link had failed. Manufactured a replacement fuse for the vacuum cleaner.
• The door to the Fisher Scientific drying chamber in Physical Properties would not seal correctly, this was allowing the desiccant to saturate with water. The door latch was bent back into shape to seal the door properly.
• Zebra printers have adhesive coming off of the labels and gumming up the machines. Cleaning them every 6 hours with Isopropyl Alcohol seemed to help. After applying some car wax to the slide bar the problem ceased.
• The Laser Door seal failed and during investigation the lower door hinge was found to be worn. This was replaced and a small patch of Velcro was added to the sealing surface of the door.
• Core Splitting Room: Repaired connections on the door pads. Assembled new bracket for the new water system on the Ubersaw.
• Thin Section Lab: Replace faulty transistors in amp, tested ok.
• Gym: Replaced the sprocket on the Schwinn stationary bike. Installed the electronics for the lap counter on the other bike.
• Movie Room: Cleaned, inspected and updated the Popcorn Media Player. Cleaned and inspected the UPS.
• A new Onkyo amp arrived at port call (TX-NR636), it was installed and programmed. The speakers were balanced to the new system. Reviewed with ships staff how to operate the new system. A user guide was generated to help the crew operate the system.
• Had numerous issues with the Bosc 12V drills. Continually cleaning the mud and corrosion from the drill chucks. Two drills were scrapped on this expedition, corrosion on the control boards.

Preventative Maintenance

• Changed out the Ocean Optics Halogen bulbs, Feb 5 and March 7 2016 on the SHMSL.
• -80Freezer on F Deck: Cleaned out the filter and de frosted.
• Upper Tween Stores: -80 Freezer facing forward only cools down to – 72. Cleaned out the filters on both units.
• Cleaned the filters in all of the vacuums.
• Recycled UPS batteries.

Science Movie Room User Instructions

07 FEB 2016, C. FURMAN
The entertainment system in the science movie room was recently upgraded and reconfigured due to the replacement of the audio amplifier. The old Pioneer amp is no longer in use and has been replaced with an Onkyo that has slightly different settings. The following is a brief description of how the system is now configured and what settings should be used for each of the primary modes of use.

System Diagram:

Onkyo A/V AmplifierProjector
(Video only)Sony Blu-Ray Player (BD/DVD)Popcorn Hour Media Player (STB/DVR)Samsung VHS/DVD Player (CBL/SAT)Side Panel Jacks
(Game, PC)Speakers (5.1 Ch w/ dual front pairs, Audio Only)

Connection Details:

• The Blu-Ray player (used for Blu-Ray or DVD playback w/ multichannel audio) is connected to the amplifier using an HDMI cable to the amp's BD/DVD input
• The Popocorn Hour Media Player (used for playback of media files such as MP4 video or MP3 audio, etc. from the internal hard drives or an external USB source) is connected to the amplifier using an HDMI cable to the amp's STB/DVR input. It also has one of its rear-panel USB ports connected to the side-panel USB port on the cabinet to accommodate USB hard drives, thumb drives, etc.
• The VHS/DVD player is connected to the amp's CBL/SAT input using a 3-channel composite cable (Left, Right, Video) and is NOT one of the main functions; it is there primarily to be used as a tuner so that the ship's CCTV network could be viewed on the big screen in SD quality, but this should only be set up with the assistance of an ET – normal TV should be watched elsewhere, such as the science lounge or conference room, under most circumstances
• The side panel jacks have several connections. There is a USB port that connects to the rear panel of the popcorn box, so plugging a storage device such as a thumb drive or USB hard drive into that port will allow playback of media stored there through the popcorn box. The "Component" inputs are not connected. The iPod connector is not connected. The "Composite" inputs (Red=Right, White=Left, Green=Video, normally yellow) are connected to the "Game" input on the amplifier and could be used to connect older analog devices such as a VHS player, video game console, or other such device that does not use HD output. The 3.5mm Stereo plug (labelled MP3 player) is connected to the amplifier's CD input (2 channel stereo) for audio only and can be used to connect to an MP3 player, laptop, mobile phone, or other analog 2-channel audio source. The HDMI connector on the side panel connector is connected to the amplifier's "PC" input and can be used to connect any HD source with audio and video such as a laptop with HDMI output, newer generation video game console, or other such device.
• The amplifier is directly wired to 7 full spectrum speakers plus one subwoofer and has been configured to treat those speakers as a 5.1 Channel setup with "top middle" additional front channel speakers (i.e. the front speakers are "front", the rear-most speaker pair are the "surround" speakers, and the middle speakers are set up as "top middle" in the amplifier's internal setup menus so that they get the same audio channel feeds as the fronts, with the center speaker as center and the subwoofer as a subwoofer). Additionally, the amplifier has one HDMI output line that goes to the overhead projector to provide video output. The line can carry audio, but the projector has no ability to utilize that portion of the signal – audio output is provided via the Onkyo amplifier and associated speakers only.
• The projector takes an HDMI video stream directly from the amplifier – do not attempt to change input channels on the projector, as no others are connected except the HDMI input coming from the amp – all switching between devices is accomplished at the amplifier.

Quick User Guide for Various Modes of Operation

To Watch a Blu-Ray Disc (BD) or Digital Versatile Disc (DVD), do the following:

• Turn on the Onkyo Amplifier and select the BD/DVD input
• Turn on the Sony Blu-Ray player
• Turn on the Projector
• Insert your disc in the BD/DVD player, and you can watch it in full HD w/ 5.1CH audio; no other settings need to be adjusted
• To adjust the volume during video playback, use the volume control on the amplifier or its remote control; if you have a problem with the video settings, please contact an ET at x231. Note that this player is Region 1 / Zone A (USA), so if you need to playback a DVD or BD from another region, please contact the ETs to have it converted to a media file for playback from the popcorn box (see next section) instead of trying to play the disc directly or else connect your own compatible device to the side panel jacks and play back from there.
• When you are finished, eject your disc, then switch off each of the three components (BD player, amplifier, and projector) you used – note that you must push the "off" button TWICE to power down the projector (first push, it will ask for confirmation; second push confirms)

To Watch a digital media file (MP4, MKV, AVI, MP3, etc.) using the Popcorn Hour Media Player:

• Turn on the Popcorn Hour Network Media Tank (Popcorn Box)
• Turn on the Onkyo Amplifier and set it to the STB/DVR input
• Turn on the projector
• There is no need to adjust any other settings; if you have problems, contact an ET at x231
• If you are playing back a movie, exercise video, music video, or other file from the Popcorn Box's internal hard drives, use the "source" button on the remote to select the icon for hard drives, then select the appropriate drive containing your desired media file. Navigate the menus using the remote's arrow keys with the center "enter" button to select and the "return" button to go back one level.
• If you wish you play back your own media files from a personal storage device such as a thumb drive or USB hard drive, please connect your device using either the front-panel USB ports on the Popcorn Box itself or the USB port on the side-panel of the media rack (do NOT use the USB port on the amplifier!), and then navigate to your storage device once it is recognized by using the "source" button on the remote to select the USB device and then navigate the menus as you would for the internal hard drives
• Note that while there is a volume control on the popcorn hour remote, this should NOT be used – the popcorn hour audio level should always be set to "+1"; if you wish to adjust the volume, use the volume knob on the amplifier or the volume buttons on the amplifier remote, not the popcorn hour one.
• When you are finished, if you have connected a personal storage device, you may disconnect it at any time while media playback is NOT in progress, then power down each of the three components you used (Popcorn box, amplifier, and projector). Note that it takes TWO pushes of the "off" button to switch off the projector

To view the ship's CCTV network (AFN, rig cameras, etc.) using the VHS/DVD player as a tuner:

• Turn on the Samsung VHS/DVD combo player
• Turn on the Onkyo Amplifier and set it to the CBL/SAT input
• Turn on the Projector
• Make sure the VHS player is in VHS mode – there is a select button on the remote and another on the face of the device itself – as you will be using the internal tuner, which is only active for VHS
• Select the desired channel using the channel buttons on the VHS player remote or front-panel
• Adjust the audio level as desired using the volume controls on the amplifier or amplifier remote, not the VHS player one
• When you are finished, switch off each of the three devices you used (VHS player, Amplifier, and projector); note that it takes TWO pushes of the off button to switch off the projector.

To listen to audio from an external stereo source such as an MP3 player or laptop audio-out port, etc.:

• Place your device on the shelf to the right of the media rack – there is a power jack on the wall there, if required
• Connect the 3.5mm Stereo lead (tagged MP3 Player) to the headphone jack on your device and set the volume to a reasonably high level on your device (50% - 75% typically – this will vary by device)
• Turn on the amplifier and select the "CD" input
• There should be no need to adjust any other settings; for help, contact the ET on duty at x231
• Play back the audio from your device as per manufacturer's instructions (varies by device)
• Adjust the volume of your device at the beginning to a high enough value that the amplifier can handle it, but do not turn it up so much that the speakers crackle (over modulate); then use the volume knob on the amplifier or the buttons on its remote to adjust volume to the desired listening level
• When you are finished, switch off the amplifier and disconnect your device

To playback HD output from a personal device such as a laptop or video game console:

• Place your device on the shelf to the right of the media rack and connect it using your own HDMI cable to the HDMI input on the side of the rack. There is a power jack on the wall, if one is required.
• Turn on the amplifier and select the "PC" input – this will take both video and audio over HDMI
• Turn on the projector
• There should be no need to adjust other settings; for help contact the ET on duty at x231
• Configure your device to output video to the HDMI output connected to the media system – the system will work best with 1080i video output up to 60 FPS and virtually any common audio format.
• Use the volume control on the amplifier to adjust audio volume to the desired level
• Playback media using your device as per manufacturer's instructions
• When you are finished, disconnect your device and switch off all of the components you used (amplifier and projector); note that you must push the "off" button twice to deactivate the projector.

To playback SD content from a personal device such as an older generation game console:

• Place your device on the shelf to the right of the media rack and connect it to the "Composite" inputs using your own composite 3-channel A/V cable. The right audio channel connects to the red jack; the left audio to the white jack, and the composite video stream to the green jack (this is typically the yellow plug on the cable). Note that this input is NOT to be used for Component video stream (i.e. discrete red/blue/green video channels without audio) – doing so may damage the amplifier and/or your device. There is a power jack on the wall if you need it.
• Turn on the amplifier and set it to the "Game" input
• Turn on the projector
• There should be no need to adjust any other settings; if you need help, call an ET at x231
• Configure your device to output to its composite video port and playback your media as per manufacturer's instructions
• When you are finished, disconnect your device and switch off the components you have used (amplifier and projector); note that you must press the "off" button twice to power down the projector.

For any other configuration, please contact the IODP ET on duty at x231.

General Tips:

• Make sure all of the devices required for the desired mode are switched on (and connected, if using any of your own personal hardware)
• Note that it takes a minute for the projector to warm up when it is turned on, so be patient
• Note that you must press the "off" button TWICE to switch off the projector – the first press brings up a dialog asking if you wish to switch it off or not; the second press selects "yes" and causes it to actually power off. Please be sure to switch it off when you are finished to conserve bulb life!!!
• The amplifier is the "brain" of the whole outfit and should always be used to select input devices as well as set the volume level. You can select inputs by pressing the appropriate button on the front panel or on the remote. Likewise, the volume can be adjusted using the knob on the amplifier or the buttons on the remote.
• If you find a remote with dead batteries, please contact the ET on duty for replacements – do NOT just take them from another remote without telling anyone!
• If you have a DVD or blu-ray disc that is not compatible with the players provided, you may connect your own player to the side panel jacks or ask the ET on duty for assistance with converting your media into a digital format that is region-free and can be played back from the popcorn box.
• When in doubt, if you have any problems or need a special configuration, please contact the ET on duty at x231 for assistance
• Do not make unauthorized changes to the wiring or settings of the system – if you need something changed, the ET on duty will be happy to assist you; making unauthorized changes without consulting the ET will result in you being banned from using the equipment for the remainder of the expedition!
• If you have media you wish you use regularly (i.e. an exercise video you use every day, etc.) that you would like to have installed on the popcorn box rather than having to bring your own storage device every time, please ask an ET for assistance.
• If you have any problem of any kind with the system, do not start poking around at settings – call an ET for help at x231!!!!

CURATION AND SAMPLING

Pre-site to Site Conversion

CATWALK SAMPLING

The catwalk sample plan for U1474A, U1475B, U1476A, and U1478A is listed below.
Mudline Sample:

• A mudline sample was collected in a bucket for U1474A, U1474C, U1475A, U1476A, U1476E, U1477A, U1478A, U1478C, U1478D, U1479A, U1479B, U1479D, U1479I.
• This sample was entered at the top of 1H1 with an offset of 0.0 cm and volume of 5,000 cm3.

Interstitial Water (IW) Samples:

• Figure 1 details the IW sample plan.
• 0 to 200 meters: 1 per Core and every other Core for ½ APC.
• 200 meters to TD: 1 every 3rd Core and 1 every 6th Core for ½ APC.
• Increased to 10-15 cm when water content decreased.
• Bottom of Section 6. If interval was found to be disturbed, the sample location was adjusted.

Head Space (HS) Sample:

• Taken below IW sample:
• 5cc plug.
• Small pieces were taken for lithified material.

PAL Sample:

• 5 cm Whole Round (WRND) from bottom of Core Catcher.
• Splits were taken for foraminifera and nannofossils.

Ancillary Project Letter (APL)

An Ancillary Project Letter (APL) was approved for Expedition 361. This consisted of high resolution sampling from 0-150m in selected holes. This was implemented on U1474B, U1475D, U1476B, and U1478B

• Figure 2 details the IW sample plan.
• One 5 cm Whole Round (WRND) was taken from the bottoms of Sections 1-6.
• The liquids acquired are being sent to Sophia Hines at the California Institute of Technology who serves as the APL science representative.
• Three additional 5 cm WRNDs were taken above APL sample for Cores 1-3 for shipboard analysis.
• Increased to 10-15 cm when water content decreased.
• There was significant heave on Site U1475. This caused disturbance in the tops of the cores collected at this site. To accommodate for this we took an additional IW sample at the bottom of Section 7 for U1475D. This is illustrated in Figure 3.

Non APL Sites (U1477, U1479):
For Sites U1477 and U1479 we did not drill a hole dedicated to the APL. The catwalk sample plan for U1477A, and U1479A is outlined in Figure 4. The PAL and HS remained the same as illustrated in Figure 1. The IW sample plan for these sites is listed below.

• For Cores 1H-3H a 5cm WRND was taken at the bottom of Sections 2, 4, and 6.
• For Cores 4H-200m a 5cm WRND was taken from the bottom of Section 6. For ½ APC Cores every other core was sampled.
• For 200m to total depth a 5 cm WRND was taken from the bottom of Section 6 every 3rd Core. 1 every 6th core for ½ APC cores.

Other Samples Taken from Section before Splitting:

Rhizon Samples:

• Rhizon sample were taken for Dr. Rebecca Robison U1475D, U1476B
• A split was used for shipboard nitrate analysis
• The remainder is being sent to Dr. Robison (ROBI).

SAMPLE TABLE SAMPLING

The general shipboard sample plan for Exp. 361 is listed below. Slight variations were made for individual sites depending on recovery and core flow.

ACTION ITEMS

Nine shore based requests were submitted by Adkins, Charidemou, Goldstein, Latimer, McClymont, Micallef, Sloss, Takayangi, and Ziegler. These will be reviewed by John Firth before the Expedition 361 Sample Party.

MISCELLANEOUS

• Play Core-A couple of mudline cores were greater than 9.5 meters. These were missed mudlines since we do not know how far these cores penetrated the water/sediment interface. These core were entered as Site/Hole/Core and run through the Whole Round track systems. 361-U1474G-1H was not used in the science splice and will not be used in the future for expedition science. The Exp. 361 SAC decided not to split this core and donated it to the JR for testing and training.
• Herman Miller Chair-The seat on the curator's chair was replaced on this expedition.

PUBLICATIONS REPORT

KEITH DUPIS
This is the Publications Specialist's summary report for Expedition 361. It is separated into two main sections: Publications summary and YEOP summary. There were no persistent problems to report.

Publications summary

• Visual Core Descriptions (VCDs) were created for six sites on Expedition 361.
• Core description and physical properties data were downloaded and plotted to create the VCDs. The data were plotted daily using Golden Software's Strater program. The VCDs were posted to Uservol on the Ship's Server as .pdf files. A legend/key figure was created to define the VCD patterns and symbols. Hole summaries and recovery plots were produced for each hole. The Hole summaries were included in the Sedimentology reports.
• The sediment VCD template/header is shown in the figure below. The scientists chose the layout. They used a graphical list of previous Expedition VCDs to communicate their preferences.
• Expedition 361 VCD Headers

• The software programs used to download data and create the VCD's were:
  • IODP Lims2Excel
  • IODP DESCLogik version 14.0.0.0
  • Golden Software - Strater 4.1.1156 (64-bit)
  • Microsoft Excel + macros for pre-processing data
• Software comments: There were no persistent software issues to report.

Report Tracking

• The Expedition Report has seven chapters:

1. Methods
2. Site U1474
3. Site U1475
4. Site U1476
5. Site U1477
6. Site U1478
7. Site U1479

• Each chapter has ten sections:

1. Background and Objectives (Introduction for Methods chapter)
2. Operations
3. Sedimentology
4. Physical Properties
5. Micropaleontology
6. Paleomagnetism
7. Stratigraphic correlation
8. Geochemistry
9. Downhole measurements (Site U1479 only)

DEVELOPER'S REPORT

ALGIE MORGAN & JON HOWELL

Overview

This document highlights changes to the JOIDES Resolution laboratory data management environment during Expedition 361.
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.

WORK IN PROGRESS

During 361 the developers actively participated in development of:

• Redesign and rebuild of REST Web Services, scheduled for deployment prior to begin of Expedition 362
• SRM upgrade to IMS, to be completed by the end of the second tie-up 361P-2

Curation and Core Handling

SAMPLE MASTER

• Changed. Operating at release 10.5
• Fixed bug in copy-paste functions, mostly for entering samples on the Sample Table tab; also affects copy – paste operations on other tabs.

Geology

DESCLogik

• Changed. Operating with release 14.1.
• Release 14 incorporates these changes.
  • The operator specified sample and offsets are now honored for both single-tab and all-tabs downloads. Previous version only honored the sample top and bottom depths ignoring any further restrictions on interval.
  • For Piece List columns. Now only the whole piece data is retrieved, not the splits. Minor efficiency improvement time the number of pieces looked up.
• Release 14 is intended to be distributed with resteasy-desclogik-services 6. The getDescData service was revised for greater efficiency of operation when some types of template and tab based queries are conducted. The combined products are only being vetted for the remaining few days of the expedition and then rolled back.

Virtual core composite GENERATION (aka Virtual Photo Table)

• No change. Operating with release 4.0 since tie-up 349P.

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 10.

• Version 9: Added new "drilling disturbance" data type; several groups of correlation specialists have requested this capability. This version of the SCORS downloader requires version 16 of resteasy-scors web services.
• Note that the data for this data type is compiled from the DESC analysis and it relies on long-standing conventions used for naming components and on the DESClogik templates. If these naming conventions are changed in the future it will likely result in breaking this feature in the downloader. This was all discussed with DESClogik techs and DESClogik project manager before adding this feature to the downloader.
• Version 10: fixed two bugs in writing section-summary file:
  • It did not honor the "Append core to hole information" option yielding different results for section-summary and data file behaviors.
  • Renamed file-headers to conform to Correlator 2.1 requirements: "Type" header renamed to "CoreType".

SCORS Splice File Fixer

• Changed. Operating with release 9.
• Minor change in this application to accommodate change in output format of affine tables by Correlator. Correlator 2.0 and prior versions wrote affine and splice table files without "Expedition" column. Beginning with Correlator 2.1rc the affine and splice file tables included a new column for expedition; titled "Exp"

Scors aFFINE/SPLICE uPLOADER

• Changed. Operating with release 3.
• Fixed bug that caused hole-list to be accumulated incorrectly while building up affine and splice tables.

Microscopy and Imaging

360 ImagE Composite Processor

• No change. Operating with release 4 since Exp 359.

Geophysics

Whole-round logger (WRMSL), Special task logger (STMSL)

Expedition 361 debuted the new IMS 9.0 software for both the WRMSL and STMSL. Additional testing and debugging were done during the first transit. The new software brings these two tracks into compliance with the common coding structure in place on the SHIL and SHMSL.
Thanks to the effort of the staff, numerous issues were identified and fixed early on. The program has been operating for the last half of the expedition without changes and is very stable. However, there are a number of known issues that need to be addressed in tie-up that are listed at the end of this section. The Quick Start and User guides are under development and should be completed by the end of the expedition. Copies in their latest revision will be left on the desktop of both systems.
In addition to the software upgrades, both tracks were converted to use the new M-Drive servo motor systems. The current interface boards will see one more revision by the end of the tie-up period which will allow the program to sense and recover from an emergency stop event.
Outstanding Issues:

• Using the Standard editor can corrupt the configuration file. Does not happen every time. The cause need further investigation and remediation.
• The emergency stop while disabling motion control does not cause an error condition in the software. Measurements continue as thought the track is still running. A new version of the interface board will correct this issue.
• Some miss-information on the setup screens.
• MS Setup needs a full revision. The MS correction process need to be revised to accommodate both paleomagnetics studies and correlation needs. Information left from the MS probe operation on the SHMSL are not needed on the WRMSL/STMSL version… can be confusing.
• Need to remount the top-of-section switch so that mud cannot cover the sensor. Also, mounting needs to avoid the situation where the beam passes thru the center. Clear objects can actually act as lenses and increase the signal to the sensor rather than the other way around. Lensing occurs when the beam is shines thru the exact center. Moving it to the side of center solves the issue.
• The PWL calibration interface is too complicated. Easy to make mistakes. Also, should implement the telescope P-wave standard.
• Issue with MS communication that cause a dropped data.

Natural gamma Radiation (NGR)

• No change. Operating with release 4 since Exp 353P.

Section half image logger (SHIL)

• No change. Running IMS 8.4 using M-Drive Motion Control Module. Because changes in the interface board this M-Dive code is not the same as running on the WRMSL. By the end of 361P-2 this will updated to IMS 9.1.

Sonic velocity (GANTRY)

• Operating with release 6.1
• The caliper calibration needed 6 measurements to activate the "Save" button. In the label underneath the button it said 5. The threshold was changed to accept a minimum of 5 measurements. The program was using a structure with arrays that started indexing at zero, not 1.

Reflectance and susceptibility (SHMSL)

• No change. Operating at release IMS 9.0 but using the Galil Motion control Module. By the end of 361P-2 this will updated to IMS 9.1 and switched to the M-Drive system.

Thermal conductivity (TCON)

• No change. Third party acquisition software. Operating with vendor TCON release 5.0.0 build 7 since Exp 335.Uploader utility. No change. Operating with release 1.3.1.0 since 341S.

Moisture and density (MAD)

• No change. Operating with release 2.0.0.9 since Exp 344. Display shows different version than available in the distribution site.

Paleomagnetics

JR6A SPINNER MAGNETOMETER

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

Superconducting magnetometer (SRM section)

• No change. Operating with release 318 since Apr 2011.
• Observed issue. Do not open the Configure Instrument Panel. It hangs the system, and writes zeros to the instrument.ini configuration file. Configuration file must be restored from backup.
• Development work continued during the early transits on the new IMS9.1 software. Successfully tested M-Drive motion control, SQUID and Degausser driver code. Completed the Sample Information interface along supporting code. The development cycle is at the point where we need full access to the hardware to complete integrated testing. Currently schedule to complete development by the end of 361P-2.

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 359.
• 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.
• Early in Expedition 361 it was observed that MUT would "stick" and fail to auto-upload; files would accumulate in upload folder but MUT would not add them to the files-to-process list. Clicking "Refresh" button would cause files to appear in upload grid so they could be uploaded. Application had to be fully closed and restarted to get it to begin uploading files automatically again; after one or two upload operations it would "stick" again.
• Version 15 added feature to actively poll upload folders based on a time interval configurable by user.
• Version 15 also contains modification to LSIMG analysis implementation class; this version causes all LSIMG uploads to happen sequentially. Other analyses will launch up to three uploads concurrently. It was observed that allowing multiple uploads of LSIMG would overload web servers, therefore decision was made to limit LSIMG so that it performed all uploads sequentially.

LORE

• Changed. Operating with Release 14.
• Code changes allow for the use of the (, ), _, and – characters to be put into the Sample name field as these are legal values for samples where measurements of depth are added to the name.
• Added a Reverse Sort Order to Expedition so most recent Expeditions sort to the top of the selection drop down.

LIME

• Changed. Operating with Release 6.0.
• 5.3 Code Changes: allow for the use of the (, ), _, and – characters to be put into the Sample name field of the EDIT SAMPLE screen as these are legal values for samples where measurements of depth are added to the name.
• 6.0 Code Changes: Added new Screen "Display Samples" that allows users with the "Display Sample" authorization to access a panel where they have the standard Selection Criteria used for all Sample functions. The Action Button is replaced with "DOWNLOAD SAMPLES" that takes the "searched" samples to a local machine CSV file quickly.

Thin Section Report Builder

• No change. Operating at version 3 since Exp 360.

Thin Section Report Writer

• No change. Operating at release 1.2 since Exp 356.

WebTabular reports

• No change. Operating with Release 7 since Exp 355.
• The WTR report drillers report is still used by the Operations Manager, OIM, and photographer.

Libraries

• 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. Worked with MCS's to set up port side of Education Office for use by developers. Over the course of this expedition noon-to-midnight developer continued to work in old developer office on lower-tween deck while midnight-to-noon developer shared Education office with E & O representative. Initial impression is that developer relocating to F-Deck works well for several reasons:
  • Expedition technicians appreciated that software developer is more accessible and closer to labs, yielding faster response time if developer assistance is required in one of the labs.
  • F-Deck workspace is generally better lighted and less noisy than office in lower-tween, making for a better working environment.
• Negatives to consider:
  • There is somewhat less total space in the Education office since we share that space with the E & O representatives.
  • Potential for greater space constraints if there are two (or more) E & O representatives. Expedition 361 was a special case since we sailed with only one E & O representative.
  • Potential for undesirable work environment if office becomes a gathering or meeting place for people visiting E & O representatives.

Desktops

• No change.

Servers

• Load Balancing. Rainier is configured to be in the load balancer, but it is by default disabled. Ararat and Shasta carried the entire laboratory data load. Issues only observed when conducting mass 360 composite uploads, or when conducting 3 or more all-hole, all-tab DESCLogik downloads.
• 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 353, 355, 356, 359, 360 and Janus samples have been loaded on the system. In terms of data queries and data modifications, this system is much faster and more efficient than the production system.
  • Olympus 165.91.150.123.
    • A virtual OES SUSE Linux node running Tomcat over a file system with 1 TiB of disk space attached.
    • ASMAN and normal LIMS services have been run end-to-end through this server. A large number of WRLSC image pairs were uploaded to exercise this system.
    • An expedition's worth of LSIMGs was load via MUT through this server change in Java version. OES was updated to new version during last tie-up.
• New production Tomcats. Two virtual servers have been spun up. They are intended to replace Ararat and Rainier. If the next expedition desires, these systems may be put into service immediately. To use these servers with the load balancer, their addresses must be added to that configuration.
  • Matterhorn.
  • ElCapitan.
• BuildJR. Changed. Updated these software packages.
  • 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).
  • Matterhorn and ElCapitan presently contain web-services and applications built to address the ODA server. This configuration may be scrapped. The boxes are production ready. Snapshot the WAR files from Ararat or Shasta to make these production ready against the existing Solaris database server.
  • Olympus. Is configured with trunk builds of web-services and applications. These address the ODA system.
  • Olympus carries a tasapps distribution directory. Access it via WinSCP and the directory /opt/tomcat/webapps/ROOT/tasapps. The content there is specifically targeted for use against the SHIPT environment (with the ODA database).
  • BuildJR carries a tasapps 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.

SYSTEM MANAGER'S REPORT

MIKE HODGE AND JAMES GILLETTE

Servers (Microsoft):

• No issues or changes to report.

Servers (Linux):

• Server Cleveland has been setup as SMT update repository for all Novell Linux servers. Was discovered that Cleveland was pointing to https://nu.novell.com for its updates while also running an SMT update repository duplicating update downloads. Re-configured server Cleveland to point to local SMT update repository for its own updates.
• Per request from the developers updated Tomcat on server Olympus (future replacement for web uploads to Asman) to version 1.8 from 1.7 and made necessary configurations for ship environment.

Servers (oracle):

• OEMJR updates were starting to exceed disk space capacity on local boot partition. A new partition was created for OEMJR updates and directory /var with OEMJR updates was moved to this new location.
• On March 1^st during afternoon break users called exclaiming that web apps stopped working. Reviewed CommVault tape backup process and found Oracle backups had paused with RMAN (ORA-16038 errors), users started calling about ~30 minutes after backups had started. Disk space for /U02 was down to 18MB whereas it was at 22GB at BOX. What had happen was RMAN archivelogfiles did not have enough space to write to disk and had paused awaiting for disk space to complete. Jon (developer) went thru archivelogfile directories and found a file with only 512 bytes that could not be opened. Upon deleting this file he was able to do archivelogfile cleanup and CommVault backups resumed and completed.
  • The original reason web apps stopped was due to Oracle database was not fetching/returning data for the requested web app queries.
  • Shore personnel reviewed server disk space and performed addition disk cleanup on Oracle volume /u02. This eventually freed up ~57GB of space.
• Continued effort to patch current our OEM installation. Was successful in getting all patches downloaded local to OEM server but, configuration issues persist. Two Oracle support tickets were opened on various aspects of the problem and working with vendor on resolution.

Servers (VMware):

• Upon mounting new OEM partition and migration of /var to new partition VMware console window access to OEMJR GUI lost keyboard and mouse support. Ticket SR16893668402 was opened with vendor for assistance. VMware Tools with mouse and keyboard support were installed 4 times two different ways unsuccessfully. A 5^th method was identified to install open source VMware Tools but, documentations states that it is for version 7 of Oracle Linux, we currently run version 6.5. VMware's latest recommendation is for us to update OS to Oracle Linux version 7. Other means are available for OEM GUI access and latest VMware suggestion would make ship version inconsistent with shore version. This has stalled pending further research.

EVA4000 SAN:

• No issues or changes to report.

3PAR SAN:

• No issues or changes to report.

Network:

• Certain workstations with internet access were experiencing print issues. Was discovered that iPrint was resolving to wrong IP address caused by shore DNS servers. Looking at shore IP assignments showed wrong IP assignment. Notified shore to implement correct IP assignment for ship iPrint services which have been implemented by shore personnel.
• Renewed JR Dell SonicWALL firewall appliance license.
• Was indirectly informed by TAMU Network Security Team on campus that the "conficker-worm" malware was encountered in ship environment. They isolated it to two IP assignments. One was assigned to a workstation and other was identified to our wireless network. The workstation was thoroughly vetted and found clean. Wireless user was unidentifiable. Instead URLs associated for the malware were content filtered for blockage and occurrence in ship firewall. The malware has not been seen since implementation of blockage and no further occurrences have been logged or flagged by TAMU Network Security Team.

PC Workstations:

• Six Dell M4400 spare laptops were rebuilt and a system image captured. They were thoroughly cleaned and new heat sink compound applied to processors.
• Two Dell E6430 laptops were rebuilt and a system image captured.
• Installed SolidWorks 2016 on LO's PC52709 and licensed current. Was not able to install software on Engineering PC52481 due to software is now only 64-bit version. Because of Rigwatch software PC52481 is 32-bit OS.
• Touch feature on several touch screens in Corelab were disabled due to differences in usage between the crews. Touch screens were enabled on all disabled screens for this expedition.
• Three new Dell P2314T Touch screens were installed to replace failed HP L2105tm units. Discovered on occasion that they would lose their touch capabilities. Unplugging and re-plugging USB cable between monitor and PC resolved issue. Suspect problem may be associated with usage of hub for connecting multiple devices into the PC.

MAC Workstations:

• Two 30" monitors were setup for the Co-Chief scientists to use with their laptops in Staff Scientist's office.
• Education Outreach Teacher had repeatedly reported issues about slow connection and how long it takes to upload photos to the JOIDES Resolution blog website. In an effort to improve performance pipelining and extended caching options were enabled on EO MAC52631 Firefox browser. This will allow their browser to make simultaneous requests to the website and allow caching of larger data and applets (i.e. blog and pictures) which will improve the "responsiveness" of the blog site and its posting. Feedback from EO teacher has been positive about these changes.
• Mac VDU MAC52610 failed in Userroom. This unit will be shipped to shore for repairs and was replaced with a spare unit.

Printers:

• CTShop HP5200 printer would incur an error code 49.4200 on display status screen and would require a power cycle to become usable. Error would reoccur frequently. Applied firmware update but, did not resolve matter. Ultimately, swapped MCS HP5200 with CTShop's failing unit restored printer usability for CTShop. Setup CTShop's original printer in MCS office and investigating corrective action to pursue.
• The Zebra printers have had ongoing problems with sticky labels, darkness settings resetting and printing un-scan able IR codes. To fix the problems we upgraded the firmware on all Zebra Printers to the newest version available. This has improved the performance and print quality of the printing overall. To address the "stickiness" problem, we tied up the "Dancing Plate" assembly that was in direct contact with the label ribbon. This, in addition to regular cleaning of the printer, has dramatically improved the overall performance of the printing. Unfortunately, the printer is still, on occasion, resetting its printing settings during power off events. We will be logging an issue with the company to try and resolve this issue. Shore has informed us they will be purchasing the Zebra branded labels instead of the third party ones. Buying those labels should remove the sticky problem all together. We will continue to monitor the label printers and mitigate any continuing issues with these printers.

satellite/Internet/Phones:

• Rignet satellite service provider recently received some spare equipment from slow-downs in Gulf of Mexico. As a test they offered for us their Riverbed WAN Optimizer for a trail usage. Plans were made and unit installed. Some before and after tests were conducted in an attempt to measure bandwidth performance. First test was for 8 specific commonly accessed URLs. Before times showed 15 minutes to resolve all 8 URLs, after showed 9 minutes. Second test was for four specific scientist's email access to their institutions. With optimization enabled all participants were able to resolve and access their institutions. With optimization off one scientist was not able to resolve at all over a 30 minute window. Two others required multiple attempts to resolve. Overall, the Riverbed appliance is viewed favorably and recommended to keep.
• Satellite outages due to TAMU network maintenances on March 12^th and 17^th, duration about 30 minutes each.
• Rignet informed ship that the Spring Equinox has started. We could possibly see short duration outages of up to ~30 minutes starting 20Mar16 thru 07Apr16. Ship personnel have been informed and requested Operations Supervisor to inform Siem personnel.
• VSAT outages of short duration on March 2^nd & 3^rd, duration less than 10 minutes for both instances.

Other Equipment/Projects:

• On March 7^th Aux AC tripped a breaker and caused server room to start heating up. Early intervention minimized heat buildup.
• DP Gyro Serial-to-Ethernet adapter was re-appropriated on Expedition 360. New unit was configured and installed in DP on Expedition 361 for gyro feed to UWGL WinFrog stations.
• AC belt swap Feb 9^th & 29^th.
• Three Dell P2314T Touch Screen Monitors installed, AMS locations for monitors have been updated.

Engineering Report

Mike Meiring
Mauritius to Cape-Town SA (30 January to 31 March 2016)

OVERVIEW:

The main task for this expedition was to assemble the VIT Surface Telemetry box and re-fit Telemetry Pod S/N 1 with the new Seaview Telemetry cards. Pod S/N 2 will not be converted and all Surface VIT parts will be kept in the unlikely event we have to revert back to the Network telemetry.

ENGINEERING WORK SPACE:

Created Engineering work space with LED lighting and solder station aft end of DHML.

SEAVIEW VIT TELEMETRY SYSTEM:

SURFACE TELEMETRY BOX:

• Installed Seaview telemetry cards, Black Magic converters, Optical distribution parts and Power supplies in 4U 19" BOX.
• Wired I/O's to backplane connectors.

TELEMETRY POD:

• Replaced 7 port end-cap with 11 port endcap.

Mounting holes for center optical connector were changed from 10-32 to ¼-20. Discovered ¼-20 bolts could not pass through the flange holes in the connector. Siem mechanic drilled/tapped 10-32 holes at 45deg offset. The 2nd endcap needs to be modified in same way during CT tie-up. Wired end-cap connectors to distribution boards

• Removed redundant telemetry parts from Pod S/N 1 and installed Seaview telemetry cards. Connected to p-supplies and wired card I/O's to output ports.

SYSTEM TEST:

Completed the optical links between the Telemetry pod and Surface Telemetry box including a 15 dB, 25 dB and 25 dB attenuator in optical links OF-1, OF-2 and OF-3 respectively. The FORJ/Slipring was included in link. Actual link attenuation can only be measured when optical cable from winch to Subsea to DP has been pulled in and terminated, but is expected to be better than calculated.

• When power was applied, LED indicators on all cards for "Power" and "Link established" came on.
• 3 x SD Video inputs each on both SS 109 card sets functional.
• Serial inputs 3-8 on both SS-109 card sets showed activity on both TX and RX indicators, confirming correct wiring and circuit functionality.
• Both CH1 and CH2 on the SS-309 HD Video cards functional.
• On SS-209 GB card, confirmed both Port 1 and 2 functional. Port3 and not wired/not checked.
• Port 3 and Port 4 HD Camera "Survey" and Re-entry respectively both functional with RS 232 controls and HD Video.
• Re-entry camera NTSC video output, when switched, functional to Surface telemetry box.

SLIPRING/FORJ:

• Measured insertion loss on both FORJ's, S/N's 1518 and 1519 with both OTDR and power source/meter. At 1550nm measurements varied between -0.8 and -3.6dB. All better than the -4dB spec.
• Prepared both FORJ's for installation by installing pressure gland at winch-end and waterproofing cable entry.
• Small Pelican-type case modified to store the spare FORJ.
• Machining to deepen bore in drum shaft to accommodate FORJ, to be done first half of tie-up in CT.
• Spacer, gaskets, bolts, glands and flexible protective tubing for installing FORJ all in a box in Subsea, marked as such.

SUBSEA:

The "Subsea FO-J BOX" was installed and a mounting for the optical splitter fabricated. FO connectors with patch-cords installed and splice-tray mounted. Outstanding is the FO cable from Winch and DP that will be pulled in and terminated during CT tie-up.
The "Subsea VIT J-BOX" was stripped of redundant parts. The Seaview SS-309 HD Video board, Black Magic SDI/HDMI converter and optical interface parts were installed. Functionality of video circuits to Subsea monitor and Drill-shack confirmed. Outstanding is a SC to SC optical patch-cord from the adjacent FO j-box. Patch cord on order.

FO CABLE:

• FO J-BOXES were installed in Subsea and DP.
• Siem plans to pull in the FO cable from Winch to Subsea to DP during first half of CT tie-up.

AS BUILT SCHEMATICS/DIAGRAMS:

• Available at: P:\2-Engineering Files\VIT\0 SEAVIEW VIT Telemetry\SCHEMATICS\Schematics pdf 03202016

FCB-H11 HD CAMERA:

• Installed a Sony FCB-H11 HD camera in the second Kongsberg pressure vessel (S/N 2). It is similar to the Survey HD camera with the only difference, the "wider field of view" optical port in the pressure vessel.
• Wired both cameras to output a NTSC composite video signal on connector pin 4, when commanded to, via RS232. This feature will offer redundancy in the case of the Seaview HD card failing.
• Replaced o-rings in Survey camera S/N 1 and installed a dc-dc converter to allow operation from the standard 24v supply.
• We now have two HD cameras in smaller pressure vessels, S/N 1&2 with a spare HD camera only. We also have two SD cameras installed in the larger pressure vessels S/N SD1&SD2 with a spare SD camera only.

ERS PROXIMITY SW.

The Hall-effect proximity switch indicating the presence of a tool in the RS latch failed during the Exp 359 test. The initial assumption was that the failure was due to hydrostatic pressure on the Hall-effect semiconductor device but has to be verified. Some development is required to rectify this failure. It was decided to have a work-around ready for deployment on Exp 362./366
An IE4M plug was modified and used in place of the Hall-effect sensor plug. When a pulling neck enters the latch, it pushes against the spring/plug breaking a contact. Leaving the latch will relax the spring and reset the contact. Status of this contact indicates the presence or not of a fishing neck in the RS-latch.

RS-latch with plug, pulling neck "Tool Present" plug
Plug and pulling neck
Two changes have to be made to existing system to accommodate this work-around:

1. In the Electronics module) two wires have to be swopped on the MHDG-FCR 7pin connector. (Changes in wiring shown on ERS Schematic diagram)
2. In the "Pulling neck", the magnetic bolt must be replaced with standard bolt and adjusted for hole depth of 1.6"

One pulling neck has been modified. Electronics modules will be modified before end of expedition, time, sea-state permits.

RIGWATCH:

• On the first site, Rigwatch application froze periodically requiring a re-start of the application on the Master. It was eventually traced to the Altech tracer pump comms circuit in the mud-pump room. Disconnecting this circuit in the Master resolved the issue.
• Dongles expiring June 2016

SET2 TEMPERATURE TOOL S/N 540:

• Replaced broken connector and confirmed tool serviceable.

VIT UMBILICAL:

• Measured attenuation on all four umbilical fibers with OTDR and compared to traces shot when cable was accepted. No noticeable change.

MDrive

• Designed interface circuit and associated PCB for MDrive motor used on the tracks in core-lab.
