Recovered by Dave Aragon and Nicole Waite aboard SeaTow vessel Jennie Lee with Captain Nick.
Surface water samples taken with niskan bottle prior to recovery - glider logging at surface with ph on, ru30-2021-078-1-23 (0372.0023)
Comparison CTD cast done after water sampling, with SB19 s/n 1581 and ballast tank laptop.
All sensors every +5th yo, TBD 8 sec all
Slowed glider down a bit too. Try to hold out through storms.
TBD to every 4th yo @ 8 sec from 2nd @ 10
FLBBCD to every 4th yo, -4 nth yo. FLBBCD and optode off at surface.
Legendary segment

Steep climbs coming on shelf, missed it last night so did steep climbs for longer than anticipated.
Extra yo, next surfacing. A bit steeper pitch and slimmed up SBD and TBD again.
Trying to minimize time off shelf.
Also turning CC off to try to more smoothly go south.
Slimming up TBD and going to SBD min until we get safely back on the shelf. 10 sec TBD
CC back on, offshore currents.
4 yo's and TBD 8 sec every other for 200m offshore leg
CC off
Sped glider up, bad currents.
Maybe time for new air pump system, LNA?, sat phone inspection.

Missed calls from 2/28 00:47 to 06:56
Got GPS during those calls it appears.
Vacuum looks to be getting lower over time at surfacings.
