Summary

Expedition 368X, was a low recovery cruise and allowed testing of the major changes made to the NGR software that occurred during the Subic Tie-Up. Though the NGR was the major project for this Expedition, we also had minor issues on some of the other systems in the lab, these were all corrected or work arounds were found to alleviate the issues. Once testing and debugging was completed all systems ran without any major problems for the extent of the Expedition. The forward MSL track was not used for measuring core during the Expedition and instead was prepped for the installation of the X-ray imager.

One main objective for the technical staff on X368 was the cross training of the new Physical Properties technicians, Seth Frank and Beth Novak. Each individual was brought up to date on the current workings of each system within the PP Lab. As a group, we were all able to troubleshoot any bugs found on the different systems and create a bug list that will be delivered to Bill Mills at the end of the Expedition.

Physical counts were done for all inventory items in the lab; O-rings for the MAD station are in transit to the Punta Arenas port call.

Individual Measurement Systems

Moisture and Density (MAD)

  • The MAD station ran without issues on any cells.
  • There were some mistakes made by scientists, the wet mass of a sample was canceled within MADMax, but when corrected by the Developers MADMax didn't populate the corrected values. The problem was fixed, but has to be done by the Developers. Please see Developer report for additional detail.
  • The standards got set to 10cc in the database instead of 10.255, this was changed by developers to the correct value. This caused a 2% error to be seen in all cells, which was immediately corrected with the switch back to 10.255.

Technical Service

  • Cleaning and calibration were performed at the end of the Expedition. The O-Rings for all cells were replaced at the beginning of the Expedition.

Natural Gamma Radiation (NGR)

  • The NGR was upgraded to new software, and was tested extensively.
  • There is an on going  bug list available on Confluence.
  • The new QSG is representative of the upgrade, we will wait to write the UG until the software has been fully debugged.
  • Please see Appendix for a full upgrade report.

Technical Service

  • A 6-hour background was run at the beginning of coring. Calibration was performed once during the Expedition. The back door was raised and the acrylic tube was cleaned out.
  • Symbol bar code scanner was replaced with new zebra scanner

Section Half Image Logger (SHIL)

  • When the user is on the start measurement screen scanning a label, the behavior should be 1. scan label, 2. software should pull a LIMS length. Currently it is defaulting to the label length instead of the LIMS length.
  • A default is set to automatically print VCD's, this should not be a default.
  • At the beginning of the Expedition, MUT had issues uploading. The developers fixed this issue here, see developer report for more detail.

Technical Service

  • All technical service for the SHIL was performed by the Imaging Specialist
  • Symbol bar code scanner replaced with zebra scanner

Section Half MultiSensor Logger (SHMSL)

  • The SHMSL had only minor issues, at the beginning of the Expedition during testing the y-axis CW switch was hit and the motor shut down. It is not quite understood how it did this, but it was able to be corrected by resetting the m-drive board.
  • Move to safe height command in the Y-axis setup does not move correctly.  Motion looks to be only half a centimeter rather than the 3 cm entered.
  • The profile of each core appears to have a threshold limit. Seen only once when a core with variance in thickness was run, the lower part of the section was completely missed by the detectors. We are not sure what the logic is here, and will report the occurrence to Bill.
  • The software does not appear to use the Laser Profile to determine correct Y-axis motions. This caused instances where the sensors did not touch a core. The core surface was a few millimeters above the benchmark and the instruments were remaining 5mm above the core. 

Technical Service

  • Changed out QEPRO holder bands, previously the holder bands had been epoxied in place and with the changes in temperature recently they had become extremely stiff. New ones were installed and the instrument reconfigured, the downward motion is now more flexible removing the chance of a gap between the sample and the collector.
  • The halogen light source was changed once before and once during the Expedition and will require changing on the 18th of January 2019.
  • The white standard for the spectrometer was cleaned at the end of the Expedition.
  • Symbol bar code scanner replaced with zebra scanner

Shear Strength Station

  • The AVS was not used during this Expedition.

Thermal Conductivity

  • The TCON ran without issue.
  • The QSG was updated to given more detail on the Half-Space Probe.
  • The Half-Space probe was the only probe used during the expedition for both hard sediment and hard rock.
  • To help keep track of the different probes, we have entered them into AMS as property. There are three different types of probes, then each individual probe has the serial number we are familiar with on the JR.

Whole Round Image Logger (WRIL)

  • The WRIL was used for hardrock 360 images.
  • There was a consistent issue with the "green flash" but it did not hinder core flow and the imaging specialist was not concerned as long as the flash did not impact the material it self.

Whole Round Loggers

Both

Current bugs:

    • When doing a PWave calibration. If the Calibration window is opened it automatically turns off the Pwave once the window is closed. If the instrument is then turned back on, the track completely bypasses the GRA. The work around this for now is to do the Pwave calibration and close the program before running. Another issue, the GRA standard was rebuilt and the offsets changed, this needed to be updated in the software. Note, this seemed like it had been updated until we rewrote the .ini file.
    • If physical changes are made to the track the user should also adjust the values within the software (i.e., defaults for distance between top of core switch and the pusher have now changed by 1 cm with the addition of the GRA standard holder). Ditto for offsets to the three instruments.
    • Default values were changed in the code to adjust to the correct offsets, this keeps the user from having to define the top of section switch each time the software writes an .ini file. The default value was changed in the Public Data structure in the DAQ WRMSL Motion Parameters.vi.
    • Liner thickness in "Set P-WAVE Logger screen" has incorrect units. Says cm should be mm.
    • After calibration, the liner delay is not displayed in the "Set P-WAVE Logger" screen. However, the liner velocity is displayed properly.
    • Disabling the velocity filter in "Set P-WAVE Logger screen"  is not honored in practice. Track continues to apply 'out of bounds' filtering regardless during the measurement pass. Also, filter hard max is 7000 m/s which is not high enough for naked Al standard run as a core (~7200 m/s). But, behavior is inconsistent and needs further testing.
    • If you change the liner thickness in the PWL calibration screen (e.g. after using a default PWL config file) it can take an extra button push to generate reasonable liner velocities and delays.
    • When adjusting the offset to the P-wave instrument, the values are written to the Pwave .ini file as soon as the user clicks outside of the text field. If the user cancels, this incorrect value is still in the .ini file (previous value used stays in the setup window). If the software is restarted, the incorrect value is pulled from the .ini file. This does not happen for the MS or GRA.
    • Occasionally the IMS software gives an error at start up indicating a problem with the NI-scope dll files. The issue was resolved by restarting the computer.  

FWD WHOLE ROUND Logger

  • The home switch was physically moved to match the home switch on the Aft Track, 158.30cm.
  • P-Wave has been removed from the track in prep for the installation of the X-Man project.

AFT WHOLE ROUND Logger

  • Although, the P-Wave logger was not used there were still issue with the MUT uploader on P-WAVE files.
  • It was noticed that there was oil build up in the air line of the P-Wave hardware.

Velocity Gantry

  • When the power is turned off to the AR700 it resets itself to default values (specifically the baud rate). We were able to set the correct baud rate and hard code it so the value is now default.
  • During measurement if the user selects the piece caliper selection, the software does not allow an offset to be entered, instead a value of zero is set as the offset. The behavior should be selecting an offset instead of fixed zero position.

Software Issues

  • On going bug list compiled and will be forwarded to Bill at the end of 368X.
  • The whole round track software was tested extensively by Maggie and Beth, we have added all findings to the the bug list

General

  • Make sure all physical offsets on the tracks system have not changed before the Expedition, if they have changed the adjustments need to also be reflected in the software.
  • Active analysis in MUT - there were instances where we saw a purple question mark for files in MUT, this was caused because the analysis was not selected as an active analysis within MUT itself.
