Deployed by Mike Crowley and Nilsen Strandskov aboard RV Arabella out of AC.
Recovered by Travis Miles and Greg Seroka out of AC aboard RV Arabella.
Duty cycling all science sensors heavily. Lowering TBD to first couple yo's, looks like recovery Wed.
CTD on every other yo, optics every other downcast. Weather forecast doesn't look good for recovery...
Disabled heading deadband, mean heading error went to -2.5 deg to 0.
False bottom hits
!!! U_MIN_WATER_DEPTH 20 !!!
u_max_altimeter 80 m, so we can see the bottom, may need to put this back to 7 once we come in shallow to help with surface inflections.
48 s didnt work, wondering if longer the timespan the more they fall out of sync.
Trying 48 at state 7 for pressure and pitch.
SBD note: 40 s on pitch and pressure fell out of sync, trying 46 s
Optimizing SBD slowly.
Changed TBD to just downcast optics. TBD file transfer rates very slow, .6 kbps vs normal of ~1 kbps for TBD.
Turning off filter improved accuracy tremendously.
Reqd num of hits = 1
-180 cc on the dives to slow them down a bit. Also 4.5 off bottom, 4 top.
Turned off altimeter filter to see if that changes altimeter accuracy which is now about 1.5 m too deep. real_depth = m_water_depth - 1.5 m.
Light sampling, altimeter seeing the surface, trying u_max_altimeter 7 m.
3.5 off bottom, 4 from top
3 hour missions
