- LPA-10kV A Power Module was removed, cleaned, and re-seated with no improvement. The spare module was also cleaned and tested with seemingly no difference. The original module we have been using was replaced back into the unit.
- The cover of the lower unit was removed to inspect the internals. Everything was clean and dust free.
- In the upper unit, the 'brains' of the Bathy, boards A00107 S/N 6209 and A00108 S/N 6210 were taken out, cleaned and inspected for any damage.
- The spare boards S/N 5921 and S/N 5920 were installed for testingon AUG 28th. Upon installation when the software was turned on it would immediately show 'Sensor State Unknown'. It is unclear whether these boards are not functional or if they simply need a firmware upgrade/downgrade in order to work with our system. The process for updating firmware on the boards is described in the Underway section of the EXP. 350 tech report found here found here. The files needed can be found on the WF2 computer and have been copied to _IODP OFFICIAL\UW\UW User Guides and Info\2 Bathy to be backed up.
- The original boards we had been using all expedition were re-installed SEP 1st and the software began working as normal again. These are the boards that are installed as of the end of expedition. *This caused some slight confusion as it was unknown to me that the spare boards had been installed in the first place. When trying to trouble shoot the new 'Sensor State Unknown' issue I thought I was installing the spare boards when I was really putting the originals working boards back in.
Magnetometer
- Cable was taken from underway and spooled back onto the winch.
- The depth is still not being recorded properly but it was decided that we did not have the expertise on board to fix the internal electronics even if we opened it up and identified the problem.
- One short deployment was conducted during the transit back to Kristiansand. No issues running the instrument and collecting data besides the depth displaying as 0.
