ON LINE LOGBOOK TARA MICROBIOME piece off scotch inside bb3 le 12/01/2021 a 17h UTC INI CHILE LEG 1 , 11 02 2021 : PUNTA ARENAS - PUERTO MONTT . TECH : MIGUEL MOLL 13-150221 / M Moll / disassembly of SBE45 TSG and chemical C-cell and mechanical cleaning of unit, visible growth. Checked zero freq and read 2524,92 Hz Last cal dates from Dec 18 and raw freq was 2525,97 Hz postcruise. So, a bit off, but probably due to some water. SBE45 should be re-cal'd asap. 16-170221 / M Moll / restart system ko, mouse jumping, port chaos, my first time with the setup, so took a while to bring back the Windows driver management inferno back to normal life. I would suggest a cleaner setup and cabling of serial ports using industrial hardware. This seems a bit unstable. Now ok. Week 17 - 23 0221 : Running OK, no issues apparently. Went through really fresh water, when leaving main channels, seen glacier melting, saling next to Brujo Glacier, cleary ingesting icy water. Seeing low S made me doublecheck cal, but is seems ok. CTD confirmed readings, bit higher. 230221 / 19:00 UTC / M Moll-Nico / clean circuit and check filters : ACs and BB3 clean, WSCD showed some light brown film. Tygon and all tubing should be replaced and cleaned. the best is to have 2 sets and swap them. restart ok. 230221 / 19:56 UTC / DATA BACKUP TO NAS OK. PERIOD 17 - 23 02 21. 280221 / 14:16 UTC / Rutinary ceck : Found WSCD window not moving. Restarting. Maybe port. Now OK. 030321 / 09:00 UTC / found mouse going crazy / at 11:55 UTC I restarted PC and redid serial port procedure, now ok. restarting online. After restart flow shoed zero, chckd main entrance filter, lots of debris, small leaves, cleaned and now ok, RESTART w/ flow ok 12:13 UTC. 040321 / 02:38 UTC / no flow, water noise fwd, alarm fwd on, after checking, found tube to flowmeter fallen off and water flowing to the sentina, off pump and valve, redone tube, restart and now ok. about 20cm of water, needs to be pumped. 060321 / 13:45 UTC / found tsg matlab blockrd, restart pc 060321 / 18:00 UTC / stop and cleaning by Nico, restart 070321 / 21:02 UTC / stop and restart pc, doubts about recording, issues. Apparently after Nico restarting, it did not record the Golfo de Penas corssing, chcking. confirmed, no rec since last clean. 090321 / 14:06 UTC / re-cleaning of tsg circuit, main filter clogged. on anchor now for a few days in std by mode. Now restarting to chrck performance. 16:12h UTC stop after cleaning. After 30 min running ok, the pump suddenly stopped. it seems dead. we change the pump f or the spare unit and restart. 20:51h UTC, restart after changing for a new pump. Shut down after testing. 110321 / 11:08h UTC / start for nav from Cabo Raper to Puerto Montt area, for station 9. Bad weather and high swell expected. 120321 / 15:50h UTC / restart after port failure, kind of unstable, specially if cables are moved... 130321 / 01:00h UTC / found system crashed, mouse crazy again, so random, maybe some change of generator...? Restart and ok. Again a hole in the series. 130321 / 10:44h UTC / again juping , all crashed. restart ok. now stable. 23:46h UTC on anchor, stopping to backup. all shut down. 140321 / 13:40 h UTC / main entrance filtr clogged with bio stuff, stopped quickly pump to clean, now ok. 23:07h UTC stopped adq. om anchor. 160321 / 23:07h UTC / start after leaving anchor, set sail. 170321 / 23:38h UTC / finish of CHILE LEG1. Anchor in Puerto Montt. On the 19th handover to another tech.
