All Notes (7)
CTD off at surface, see if that helps with logging aborts.

Glider stayed connected for a while - tried to re-sequence, then aborted again for initialization error.
optics off below 300m
pitch set to 30 degrees for dives and climbs
undervolts abort when pumping at depth, change mission abort to 12.5 for undervolts
