- New Limit switch design for P-Wave Caliper.
- New DI water system installed in Paleo Lab. (Alex and Johanna completed Chem Lab installation.)
- Chem Lab floor repairs, and fume hood repairs were done.
- Knudsen System installed in Underway. Maggie Cable removed for protection against work done at faintail.
- New Trimble GPS Antennas also installed.
...
Installed secondary monitor next to the door for experimentation to see if it helps with easier workflow.
New 6KVA Minutemand Minuteman UPS was Installed.
The Electrical Dept. put in the new cable and 208V supply needed for the UPS.
...
Moved the core racks against eachothereach other, and a little towards the STBD side to make space for the new X-Ray system.
Painted floor where ols old rack config was.
We moved the Isoducts to the top just below the ceiling, and installed a lab air line with shut off valve for the unit.
...
We then installed them and did colour color and camera calibrations. The 1 baffel baffle was a brown color, and so it caused an eye sore.
We then received high heat black spraypaintspray-paint, and dissasembled disassembled the lights again, the give both baffles a new coat, assembled all again, with the bench test, and re installed the whole system and tyding tiding up of wires.
All 8 fans plus the High Temp Alarm run 12VDC from the same Power Supply that feeds the camera, and the heater elements inside the alluminum aluminum heatsinks run on AC Power. All of which is controlled by the Temp controllers.
...
The high temp alarm was set to 50 Degrees celciusCelsius, and the setpoints are at 30. It has a flashing red LED, and a very annoing annoying buzzer to make everyone aware that the lights are too hot, in case they failed to switch off automatically after a scan
...
- We had a problem with the left controller supplying constant power to the elements, perhaps through a stuck relay or arc inside, and it heated the block to 150Deg CelciusCelsius!
- Smaller 150W elements has been ordered for installation, since the 200W elements currently inside draws perhaps little too much Amps, though it is still inside the 5A current limit stated in the spec sheet, but since we are not heating up the heatsinks to high temps, smaller heaters will easily keep the setpoint temp steady just as good.
- We have also ordered 2 x new controllers for spare, but the current one seems fine now after we dropped down the temperature, and got the heating output relay switching, and also set the heating output to switch at a longer "refresh" time. The cooling switching is much faster, since we want a quick response for when the lights are switch on and the LED's heat up.
...
Old LED SHIL light system was stored in a P-Box on the shelf at the NGR. The unit is still complete, since we used new LED's for the new system and left the old one funtioning functioning as backup.
SRM
New Haskris was installed, in order to bypass the ship's chill water feeding directly into the compressor and causing dirt/rust build-up inside. Alex did basically all of it since it was his project.
...
Repaired and painted the floor where the previous Haskriss Haskris was.
Installed an additional "home" limit switch.
...
Purged the inside dewar with N2 for 10min after the air was off for most of the expedition, and switched on the unit to start makin making LN2.
Underway Lab
Installed new Knudsen Ecosounder system, and the correct connectors were fitted. System seems to be running very well along with the new software.
