All Notes (33)
Recovered 7 am EST 11/24 by UDEL team out of Ocean City, MD.
Glider heavily fouled, mostly fuzzies some goosenecks.
Optics on every other yo, CC off again to get onshore for servicing.
CC turned on (close to shore)
Fin abort was fin stuck hardover at -18.6 coming up from first yo. Didn't change fin limits.
Ran 30 min diagnostic mission (MBD) ud_476-2015-321-0-16.mbd
Seems to be flying OK, not sure why trouble navigating.
Re-sequenced mission to see if navigational slow downs are fixed.
science cutout (investigate)
Glider started calling TWR at 508, problem with their datahost lead glider to being 'stuck' at connection. Finally called Rutgers after 10 hours or so of contacting TWR.
Back on 2 hour missions and regular fish-finding.
Some altimeter ground truth segments (sampling)
And the one after.
Abort was bad goto.
Visited, cleaned, and on its way, 2 hour missions. Not changing any fin settings, but Breece has pictures. Possible barnacle interference...
Aborts have been for digifin. 2nd abort 2:41 EST 10/20 stayed out of service causing BEH errors when transferring data.
Fin was reported at recent surfacing as -.43 rad
x_fin_max was .45, lowered it to .32 assuming hardover was the problem.
MLG from 2nd fin abort was 200 KB same as MBD, worth downloading later
Tide must be coming in, brief intermediate offshore waypoint to stay out of shipping lanes.
OTIS II was recovered, cleaned, and redeployed on 10/7/2015. Had trouble w/ external VMT, so removed and added wingrail weights. Flight mechanics looked good, but over the last 24 hours, OTIS II has been retasked to search for the Blue Hen. It has heard from it several times; we are currently heading towards last known argos position.
Changed yo top inflection from 5 to 4.5 to try to get a bit more flight column since it shallow time.
Changed u_pitch_max_delta_battpos from .2 to .15, it might not do much but to try to ease the overpitching on OTIS. (causing some altimeter noise and rapid yo's)
CC back on for overnight
Onshore waypoint, no current correction until the currents relax.
Current correction ON
(back to fighting currents)
wpt -7421.7050 3820.1700
u_use_current_correction 0; tired of flying against the strong tail current
Gliders are breaching (getting gps signal). Changing climb-to to 5 m to try and keep them underwater in high seas (significant wave height 17 ft at Delaware buoy).
Changing dive-to from 27 to 25 m to avoid overdepth aborts.
OTIS II still making a bit better headway than RU28 (heavier glider), so adding southern waypoint to bring it in closer to RU28
Already losing ground to strong NE currents, so setting the wpt east. Leaving yo to full depth and 2 hour surfacings.
73 29.7310 W 39 06.8900 N
OTIS II, being the heavier glider, is flying north a bit faster than RU28, so I'm backtracking it a bit to get them closer. Mid waypoint added to the goto.
Retasked to a midpoint, then off to the NE with RU28 to weather the approaching storm. Saw some odd behavior when attempting to transfer files:
Error from wcs(00430243.TBD)
SCI: Sent 0 file(s):
SCI: FAILURE xmit_to_host(): results=1
1023784 65 Freewave console restored
REVERTING FROM SCIENCE COMMAND MODE
SCIENCE COMMAND MODE TERMINATED because:
Science Program QUIT (cts lowered)
Tried again to transfer .tbd and .vem files; no problem.
Changing waypoint to inshore DEP waypoint; matching up to fly w/ RU28.
Ctrl-F from the yo10.ma change reset the goto_l10.ma, so glider is heading back to initial (0) wpt. Changing back at this surfacing.
Changing climb-to back to 3 m; still breaching occasionally.
Changed climb-to from 2 to 2.5 m, as we were breaching:
Changed u_reqd_depth_at_surface from 4.0 to 2.0.
Changed dive-to from 5 m to 3, and changed climb-to from 3 m to 2 m to increase the water column being sampled. M. Oliver requested science data closer to surface, so may be adjusting further.
Adjusted and loaded RU28.mi (should have renamed) - altimeter settings. 7 m limit, filter is OFF.
Deployed this morning off Belmar (Shark River) by Nicole C. and Nicole W. off NJDEP vessel.
