deployment During deployment it was thought that the CTD pressure sensor was clogged or broken. Upon return to lab we found that CTD pressure sensor was definitely clogged. Numerous gooseneck barnacles were growing throughout the glider and a butter fish even popped out of the cowling.

deployment Something wrong with CTD pressure sensor...

Remora or something right on sensor or corrosion?

deployment Changed to battpos flying

turned optics off, ctd on only on upcast, changed sbd to reflect this change

trying to get through the weekend with the battery

deployment CTD pressure sensor looks fouled or plugged? Putting on short segments to diagnose if its overloading or what be it.

deployment (3:14:30 PM) dkaragon: http://marine.rutgers.edu/~kerfoot/devel/pngView/iView.php?status=active&glider=ru21&cat=segments&type=ld
(3:14:32 PM) dkaragon: this looks right
(3:14:45 PM) dkaragon: you can see it shuts the logging off on your visual sbd plot
(3:17:00 PM) dkaragon: from segment 06 to 21 of _149_000_xxx there is dupe downcast data

deployment lowered sbd size

sbd dupe problem, sensor off, sbd logging on for the state produces dupes, email being worked on to TWR

deployment 30 degrees pitch, 6 hour missions... praying

deployment CC not helping, currents high, may have to turn around in am

u_min_water_depth 80 meters to keep it diving deep
2010-05-28 13:51 GMT

deployment current correction turned off... hope this is what is causing the ground loss, otherwise its just stronger currents

deployment changed to 4 hour surfacings, no comms at 7 hours

deployment gps device error report:

back on normal missions, it obtained gps hit at surface... i think vehicle is getting < 2 m from surface turning the GPS on.

thanks.
2010-05-21 00:53 GMT
dkaragon
deployment getting close to surface < 2 m, this causes GPS to turn on, getting gps status values in sbd

sbd is large, progress is mediocre. de-convinced myself something was attached to us. Densities increasing across the board.

not sure how to decrease sbd size, best bet is to perhaps go to every 3rd up/down
