deployment Recovered outside of boating limits by Mike Brown and Palmer crew after drifting overnight w/ blown ejection weight.

deployment m_why_started: 16
# 16 -> Dbl Bus Fault
2016-03-08 11:44 GMT
haldeman
deployment Glider failed to call in throughout the day yesterday; surfaced ~12 hours later w/ blown weight. Was already on the way up when the wire started burning, but was too late. Glider aborted from initial.mi; meaning we reset underwater again. Drifted overnight; rescue mission currently underway.

haldeman
deployment Switching back to along canyon. Will set min alt later via script to 80 m.
2016-03-03 16:20 GMT
haldeman
deployment Science super abort again today; fatal error from science_reopen_log_files. Also seeing de_pump OSL and pitch_motor warnings.

deployment u_alt_min_depth 2 for cross canyon transect
2016-02-27 22:50 GMT
haldeman
deployment !!! u_alt_min_depth 80 !!!

at next surfacing.
2016-02-27 17:17 GMT
haldeman
deployment Retasking back to along canyon line. Will use set sensor script later to change u_alt_min_depth back to 80 m.
2016-02-26 14:42 GMT
haldeman
deployment u_alt_min_depth 2 (default)

Retasked for cross canyon transect.
2016-02-25 15:49 GMT
haldeman
deployment !!! u_alt_min_depth 80 !!!

Turning around at 70 m for false hits; so trying to go deeper, but will need to keep close eye on this.
2016-02-23 19:41 GMT
haldeman
deployment u_alt_min_depth 40 to account for false hits. Saw a couple of early turnarounds today. Will need to adjust for cross-canyon transect.
2016-02-23 16:48 GMT
haldeman
deployment Noticing a lot of pitch motor oddities and warnings; will need to keep an eye on this and investigate back in the lab.
2016-02-22 16:21 GMT
haldeman
deployment Switched to cross-canyon transect again on Sunday; back to along canyon on Monday. Awaiting input from Mike Brown as to when best recovery date is.

deployment app reset again Friday night. Grabbed and resequenced.

deployment APP reset 3 times today; not sure what this is about. Possible bad plug or something messing w/ the glider's tail end.

deployment Underwater reset last night; hung around SE side of cross channel section for the last few hours. Resequencing 1k_n2 and will send off down UAF line later today.

deployment RU26d was about to be retasked from cross canyon section to UAF line, but last segment had aborts for science super being taken out of service. Difficult to troubleshoot, as no .nlg created for these errors. Science super back in service, RU26d repeating cross canyon transect.

deployment Retasked to station keep near midpoint. Flying a small box, 25 m satisfying distance, single yo.

haldeman
deployment samedepth_for abort - appears glider was stuck either under an iceberg or a ledge approximately 12 m above inflection depth. Appears zcancel may have resulted in odd "emergency" state requiring Ctrl-C and a system reset to fix. Glider currently in relatively shallow water w/ south waypoint.

deployment 185.52 28 sensor: f_crush_depth = 1150 m
5392 67 sensor: f_max_working_depth = 1050 m
2016-02-01 15:41 GMT
dkaragon
deployment OD and UNREASONABLE abort were due to crush and working depth being set to 300 m in longterm. This was likely left over from previous mission (LTER leak) to prevent glider from going too deep.
