All Notes (12)
Recovered by Nicole, Lori, Ashley on SeaTow Jennie Lee. Water sampling and comparison ctd cast done with rosette and SB19plusV2 s/n 8199. Net Tows also done.
Some tcd's small or un-decodable. I think it was the result of u_science_low_power. MLG showed AZFP errors. NLG didn't show much.
Needs full investigation and feedback to Webb.
u_science_low_power not a great idea with AZFP for long periods of time, MUST monitor for oddities!
RU Logs Down Note:
Many science_super oddities, noticed this:

Will try to get MLG or NLG and turn off science low power.
Low power first yo sampling only again, another WWE
sci_low_power off
CTD, pH, AZFP back to every yo
FLBBCD back to every other yo
Power saving until get back on track
Check inflation time/pressure/vacuum on this glider, perhaps all heavily used. Noticed ru38 inflated slowly and 39's vacuum looks low?
