Not sure if there is a note on this. Pump on CTD had been failing and possibly completely failed on this mission. Heard through grapevine that a resistor had failed.

Glider had 3 digifin aborts during the course of the mission, the most recent a few hours before recovery. Should investigate.

Changed to single yos and 200 m dives in prep for AE recovery later today.

Turned northward toward Hydrostation S and pickup at the end of the week

-190/+260 speed the glider back up a day or so ago - RC

turned off low power mode 5/19 11 est surfacing to see if glider does any better vs the 25+cm/s

Changed SBDlist to add x_low_power_status, still need to generate cache file, will do so shortly.

Anna cleaned, mostly goosenecks. Nothing on the CTD inlet or outlet

Redeployed

Set fin deadband to .04

Created by: dkaragon @ 2015-05-12 09:04:35Informational

Snagged by the Stommel with Tim, Bruce, and Dylan.

First reports of goosenecks.

Inshore for recovery, 550 m dives starting 00 EST

Pump throw set to full range to increase speed against currents.

Created by: rcurry @ 2015-05-03 09:38:18Informational

Speed has slowed to 10cm/s against strong currents but also fouling. Set waypts to bring vehicle back for cleaning.

Created by: dkaragon @ 2015-04-28 16:34:48Informational

TBD has been changed a few times to diagnose possible CTD fouling problem.

2015_114_0_20 has science oddities (6) and data dropout

Changed TBDlist to 60 sec from 30 sec (5 m to 10 m resolution)

Created by: dkaragon @ 2015-04-20 09:55:02Informational

Slight slowdown noticed in vertical velocities at the start of April, as of today about 90% original speed. (fouling)

Quick look at battery capacity remaining (may update SD/day rate later if I get UMAINE's lithium death).

15+ C deployment --> 31 AH / cell * 26 = 800 AH
Pack about a year old, 3% --> 776 AH
5% for lithium end of life --> 737 AH
.425 AH / day (SD/day rate) * ~ 90 days ---> 700 AH total capacity

Fin abort:
:OOD:digifin_mgr_ctrl:OUT OF DEADBAND: M_FIN:-0.4333 C_FIN:0.4300
:OOD:digifin_mgr_ctrl:OUT OF DEADBAND: M_FIN:-0.4333 C_FIN:0.4300
1550803 23 DRIVER_WARNING:digifin:-1:digifin_v2_ctrl() Digifin movement warning.
Digifin busy too long!!!

Attempted to be put back in service 5 times automatically, went back in service the first time I tried manually.

Lowered fin limits:
get x_fin_max
= 0.310000 rad

Deadband still .04

Was stuck at -.4 as soon as the dive process started, wasn't long into the dive before aborted.

Created by: dkaragon @ 2015-03-18 17:04:40Informational

Doubled fin deadband to .04. It was back to .02 so I guess the previous didn't hold. I changed it at both locations x_fin and f_fin

Dockserver filled up its / mount, about 50/50 GB. The culprit was the /var/dockserver/log/zModem.log

I moved this file to /home/localuser/DATA/DS_Logs

Will do damage control on what data didn't get saved. Happened sometime this morning, possibly last night.

Created by: dkaragon @ 2015-03-12 17:04:28Informational

u_reqd_depth_at_surface 4 m (too many GPS hits during diving --> increased SBD size)

x_fin_deadband .04, doubled deadband of fin a) to save power but b) because there is fin slop that may cause overuse

Added b_arg: gps_postfix_wait_time(sec) 12 to surfac10 (nothing commanded). This might be too short, but investigation lead to believe that the glider gets extra GPS hits at surface but doesn't do anything with them. It does however use the dive GPS to calculate surface drift, whereas I think its supposed to do it due to postfix. It was possibly creating 60 sec of unnecessary GPS/surface time.

Shortened SBD again. Big culprit of SBD size is m_present_time @ 8 bytes. 50% of data file is the timestamp.

Created by: dkaragon @ 2015-03-11 22:39:18Informational

Shortened SBDlist for smaller file size.
