All Notes (20)
Recovered by Magali and Jerome from Agoa with Captain Marco off Martinique
Shallowing yo up to 600 m in prep for recovery tomorrow
CTD back to upcasts only after finishing StL passage.
Look at abort segment, why did sag persist to surface? Also seemed to have a sag a few days prior too.
undervolts abort.
Checked quickest example I could find ru25 amundsen with alkalines. That voltage sagged 3.5 V from 13V to about 9.5 V It drew a little over 6 A
Previous ru29 deployment at 14.4 V sagged only 1.5 V but pump drew same little over 6 A
Probably 8.5 V is getting low which is upper voltage of 8.5+ 3.5 = 12 V should shallow it up by then.
CTD to dives and climbs at next surfacing for Passage crossing.
CTD back to just climbs at next surfacing
Strange segment (final 300 m) wobble
ru29_2022_320_0_152
CTD back on ups and downs for St Vincent Passage Crossing
Turning on CTD at next surfacing full time. Will be at northern edge of St. Lucia passage overnight.
Dominica passage complete. CTD back to upcast only.
CTD on ups and downs as of late last night for passage crossing
