Post-analysis: keep an eye on power savings, may or may not be working. Say signs for both. Perhaps it works but was cancelled out on last deployment by something else?

Recovered by Dave Aragon, Nicole Waite, and Chip Haldeman on R/V Rutgers out of Tuckerton. Double recovery with RU34.

Comparison CTD cast at recovery done with SB19 a/n 1645 and ballast tank laptop.

u_alt_Reqd... was 1 I think from deploment, lots of false hits around 5-10 m but never turned around but now in the shallows it is turning around. Prob not a good settin to use, trying 2 if not follow up notes 2 worked much better.

Moved box a little south to avoid mooring.

TBD to every 4th yo. Not much spatial sampling on this mission.

Switching to a ~ 2km box to get more directions in DVL data.

u_reqd_depth_at_surface 1.75, making sure DVL running to near top.

Switched back to RU Rudics. Problem appears to be fixed. File transfer went OK.

Created by: dkaragon @ 2020-12-04 15:37:34Informational

Seems like decent steering so far with 2 deg roll, I imagine based on tank saying 0 deg that the DVL is about +- .5 deg roll reported. Fin offset about 5 degrees starboard.

Port 1 problems Twr analog?

TBDlist every 3rd, DVL on state 7 since deployment.

Created by: dkaragon @ 2020-12-03 23:03:32Informational

Changed surfac40 no_comms surface time to 390 seconds since TWR analog seems a bit unreliable with missed calls. Lowered it so glider doesn't sit on surface forever.
