deployment pump abort, glider may have developed a brake/pump problem similar to history on ru07

pump stuck moving inward, witnessed it during surface test as well

re-ran mission
2012-06-15 14:25 GMT
dkaragon
deployment yo stop_when 60 sec
4.75 m from surface

Reset goto to -1 initial waypoint
2012-06-15 13:04 GMT
dkaragon
deployment u_max_bottom_slope .4
u_hovering_frac_nom_dive_rate .3

Still impacting occassionally, backed off bottom slope filter and trying to get glider to better detect being 'stuck'.

deployment Took optode timestamp out of TBD
2012-06-14 14:39 GMT
dkaragon
deployment 3.25 off bottom, 5 off surface
2012-06-13 21:29 GMT
dkaragon
deployment Also note: no altimeter lag/inaccuracy when the filter is disabled. Our bottom samples matched where glider said altimeter was minus 1 meter for pitch angle glider pressure sensor.
2012-06-13 19:08 GMT
dkaragon
deployment Dropped optics out of the TBD, changed CTD to no longer sample at surface.

Set optics to sample 1st yo and every 24th beyond that.
2012-06-13 15:09 GMT
dkaragon
deployment Climbing to 5.25 m

Attempting the setting u_max_bottom_slope(m/m)=0.04 which is defined as altitude / horizontal

deployment .15 D battpos: lessen pitch just a little

sbd/tbd catch up script is on
2012-06-12 21:09 GMT
dkaragon
deployment Fixed battpos flying:
.2 in D
-.5 in C

Angles look good, perhaps a bit steep on the dives, but will run overnight.
2012-06-12 15:43 GMT
dkaragon
deployment Increased climb_to depth to 5.5 m to help surface time in turning GPS and other surface sensors on.
2012-06-12 13:36 GMT
dkaragon
deployment Lowered pump throw to about +- 200 c, turned off optics on downcasts.

Battery drain faster than usual. May try to trim glider up today to see if that helps with power.
2012-06-11 19:09 GMT
dkaragon
deployment That setting seemed to help, back to 3.5 off bottom.
2012-06-11 13:05 GMT
dkaragon
deployment u_max_altimeter 20

This may help get rid of surface reflections and being we're never in > 25 m of water should not impact ability to see bottom.
2012-06-10 04:24 GMT
dkaragon
deployment Increased to 4.5 m
2012-06-09 03:51 GMT
dkaragon
deployment Couple bottom samples, backed off to 4 meters off bottom. At least we have a bottom record now to compare with new altimeter settings.
2012-06-08 21:01 GMT
dkaragon
deployment So far so good, no bottom impacts at 3 m. Next is to check where bottom actually is.
2012-06-08 16:43 GMT
dkaragon
deployment 1.5 hour test with altimeter filter off

3 m off bottom
2012-06-08 15:21 GMT
dkaragon
deployment Some slight bottom sampling on a couple segments. Backed off dive to to 5.5 m off bottom.

Almost 2 m discrepancy between altimeter bottom and actual bottom (pressure record)
2012-06-07 17:48 GMT
dkaragon
deployment u_pitch_max_delta_battpos .045

Moved to next waypoint since we overshot the original waypoint.
