Glider aborted for no pitch battery movement. Battery was halted at .5 in foreward. Batt_vel was 0.0000 which only matched 2/10 battery vel on ru23 for pitch motor disconnected. No attempt was made to put pitch back into service or reset the glider. Thrusting was done on climbs (5 deg fixed pitch angle) to swim and appeared to be working.

CTD pump suspected dead as well. Noticed 3/11-12 time frame.

Recovered by David & Nicole out of AC aboard Sea Tow 26 foot. Performed CTD cast corresponding to segment ru30-2019-071-7-0
(0285.0000) on flume toughbook.

Some strange file creations, yo, goto, etc. Result of which went north for a bit and going to miss a segment of TBD FLBBCD data.

Really need to look at science oddities and get the science logging crashes figured out, pH caused? What's causing it. Surfacings from not too long before this note look strange.

Noisy CTD pressure sensor, about .25 m peak to peak.
CTD s/n 9417

Created by: dkaragon @ 2019-03-08 14:49:09Informational

TBD to every 3rd, optics on every 3rd as of PM 3/8. Heading back onshore.

Pressure sensor on this CTD looks noisy too, peak to peak about .25 m

Created by: dkaragon @ 2019-03-06 17:25:54Informational

Changed TBD to every 4th yo, perhaps until we get offshore and the winds die (1-2 days). Losing to currents currently.

Created by: dkaragon @ 2019-03-06 15:37:49Informational

Optics every other yo. May change optics and TBD to every 3rd yo after it hits waypoint.

New plan is to run ELINES as much as we can.

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

CTD off at surface starting late PM 3/5

Created by: dkaragon @ 2019-03-05 09:38:46Informational

Abort for stalled for 3 am est 3/4. Glider appeared to dive normally but abandoned dive. Thinking a timer was running during surface interval that shouldn't have been. Must have been stalled for abort timer? m_pressure was stuck for surfacing?

Created by: haldeman @ 2019-03-01 12:58:49Informational

Dave checked pressure sensor on surface; looks good. u_reqd_depth_at_surface to 2m via script, dive-to from 4.5 to 4.25m, climb-to from 4 to 3.25m; all on next surfacing.

Created by: dkaragon @ 2019-03-01 12:37:11Informational

Still pH errors turning science on/off during surfacing. Should report to TWR.
