All Notes (18)
Recovered for repositioning.
4.5hr hover 8.5 W thrust towards caldera
Up thrusts, some short segments in case boat recovers.
No thruster normal single yo's
Upcast thrusts all night long until 11:28 est switched to 4 hour at depth hover 6 W
Just completed 4 hour at depth thrust at 850 m, using these rough settings. Doing another for 3 hours at depth.

Thruster turned on again, 7 watts upcast
Turned thruster off. Going to back up into ru36 station keeping location. Single yo's
Thruster being turned on again at next surfacing on climbs, 6W (approx. 2023-06-05 14:30 UTC)
Thruster turned off 2023-06-05 02:41:56 UTC
Waypoint changed to send glider to WHOI TR Transmitter
Followed by 700 m thrust mission for 1 hour @ 7 Watts.
5 Watt thruster hover mission @ 400 m for 1 hour.
Turning CC off
Waypoint changed to bail south off Caldera and loop back around.
Double yo's, climbing to 10m, thruster to 5 W.
8 Watt upcast, 15 degrees. CC on, figthing the current.

2023-05-26 14:07:35 Changed thruster method to 4, Command input power -- set to use 6 -- climbs
2023-05-26 14:05:39 900m thrusting on climbs at 40% overnight last night
2023-05-25 22:55:55 700m yo with thrusting on climbs at 40% current correction off
2023-05-25 22:35:23 200m yo then 450m yo FLBBCD on dives and climbs down to 200m only
2023-05-25 22:34:46 iridium issues during deployment.... coinciding with sync_time attempts - which also cycles iridium. putting it in a weird state? should investigate.
