Don't remember why or what we were doing

Could not feel ctd pump in tank but it spun in lab post-dunk. May want to look at some of the last profiles to make sure OK.
Lithium performance post recovery:
Recovered 11/15/2019, analyzed 1/23/2020, 69 days ---> ~ 20% SD possible in those days
167 AH used as reported by glider
Batteries did not discharge evenly, see table below:
Total reported charge level = 60.9/227.9 AH ---> 227.9-60.9 = 167 AH
If we include SD that is about 152 used AH
Match level with glider 100% and 110% as reported by glider.
Emailing TWR to see if they should be discharging equally.

Recovered by Julia Engdahl, Joe Anarumo and Dave Aragon aboard NJDEP vessel.
CTD cast with SBE-19 s/n 1581
Thrusting 40-50% @ 15-20 deg angles last 24 hours or so.
Power usage went from about 4 AH/day to 9 AH/day
Speed went up to 40 km/day
Turned science low power off, still duty cycling science sensors @ + 4 setting. Changed TBD
u_reqd_depth_at_surface 4
We can lower that for next deployments
Right now going to set it to 2.75
u_reqd_depth_at_surface 2.75
check reqd depth at surface for this glider, may need to set shallower
optics already at -4, changed CTD to -4 and u_science_low_power 15
In case we have to last another week out there.
CTD off surface
Coulomb oddities, curious what they are, take a look post-recovery.
optics to downcasts only to save some power.
!!!!!!!!! u_max_lag_before_syncing_time 946100000 !!!!!!!!!!!
only with put, if it flies well through weekend then change to longterm_put
GPS could still rollover due to 'gps battery'. Don't sync time.
optics to every 4th yo
-200/200 cc pump
post-deploy - check out the coulomb counter warnings/oddities
-200 / 170 cc
Steering problem could be West wind. Turning us 180 to where we want to go and control system overshooting cause of hardover fin.
Some wild steering segments surrounding ru33_2019_286_3_42
If this doesn't continue definitely worth a MBD/DBD analysis.
High winds but ru22 not affected much by it.
Strange heading error and every fin of +10 deg to stay straight (veering port). Result of +5 deg roll?
Set fin offset to +5 to see if it helps. Maybe ierror kicking in at some point but not in first couple yo's.
-170/200 pump settings since deployment
Lowered TBDlist from 4 every other to 6 sec every other.
g3 8.3 spare heap abort, ben said set to 30000 from 50000?
Deployed with unpumped SB19 1581 CTD Cast
OS 8.2
CTD #9408 (cal'd 2019-06-08) pumped
FLBBCDSCL S/N 3320 (cal'd 2013-09-25)
Deployed on the RV Arabella with Nicole Waite, Captain Ken Roma and Katie Liming (MARACOOS office)
