Note regarding lithium lifetime:
2019 pH 1: 120 / 205 AH used
Lithium ions charged prior to deployment: 10.123 AH 8 23 = 232 AH
Lithium ions in lab about 44.2% charge level = 4.470 AH / cell --> (23 * 4.470) = 103 AH remaining
According to packs we used about 129 AH, glider 120 AH
5.65 / 10.123 AH used = 56 % used
120/205 = 58.5% used, pretty close
~ 205 AH for winter mission

2019-02-21 14:18:19: Cowling slightly popped off, didn't fit too snug. Foam was indeed crushed, maybe 30-40% by eye. Optode was dead, cable seemed OK.

2019-02-19 19:04:21: Glider recovered around noon est by Chip Haldeman Liza, Laura W., and Alex S. out aboard RV Rutgers.

2019-02-18 21:08:25: Switching to 2 hour missions w/ thruster on. Dives: 17.5 degrees, 45% Climbs: 15 degrees 65%

2019-02-13 14:57:11: Optode throwing errors on NLG I downloaded. U4stalk failed to communicate with it, no dialog Turned optode off in proglets.dat for now

2019-02-12 13:49:48: Inspect pitch oddities once back

2019-02-11 19:17:15: Glider had old TWR foam in it. Changed climb to 29 degrees to help VV match dives.

2019-02-11 19:16:43 Noticed diverting VV. Then noticed avg battpos goigng forward. Looks like foam started compressing 110m +. Sending back to NJ for recovery. Limited depths to 75 m, maybe more.

2019-02-10 03:32:55: Turned thruster on for 5 cm/s too slow in surfac40 # Thruster b_arg: c_stop_when_air_pump(bool) 1 b_arg: c_use_thruster(enum) 3 # 3 Command depth rate. b_arg: c_thruster_value(X) -.05 # use_thruster == 3 m/s, desired depth rate. <0 for climb

2019-02-06 18:29:22: conducted surface test for pH sensor power usage pH uses about 36 mA @ 15.75 V = .56 W Accidentally left file transfer off after strange MBD file transfer. Need to turn on next segment. ru30-2019-036-0-0 (0257.0000)

2019-02-05 16:19:09: CTD off at surface as of 2/4 12 EST and optics to every other yo as of 2/5 8 EST -180/230 cc

Keeping it on deep side until first lane. Eventually will turn off surface CTD, leave pH on for fouling prevention.

Some quick notes that will be revised:
about .2%/day liion self drain
knee is at about 12.x V, below 13 be careful
temp derating maybe 10%
23 packs of 4S3P (10.2 AH nominal)

They are charged to about 9.9 Ah, de-rate 10% and 5% for self discharge --> 8.46 AH
8.46 * 23 = 195 AH

Using that until I learn more

Deployed by Chip H., Elizabeth Fairbanks, Brandon, and Alex Sneddon out of Stonybrook out Morgan Marina aboard RV Rutgers.
