Salinity: + 0.269

Quick checked the air bladder via m_vacuum, during 1 missed call event it appeared air bladder inflated OK. Looks like solenoid is working OK.

Adding 20 cc more to pump on dives, and switching angle to 26 just to see if we can make any progress to the east. Still 260 nm offshore :-(

Going to 30 deg dives.

Both D and C @ 30 deg. See if we can lower oddities and get a speed boost.

Upcast CTD off as of 2 surfacings ago.

Created by: dkaragon @ 2016-03-06 11:31:22Informational

As of last 2 surfacings CTD upcast should have been on but didn't see it in the diagnostic plots.

As of 2 surfacings ago, set fin offset to -3 degrees. f_fin_offset -3 deg

Created by: dkaragon @ 2016-03-01 22:14:36Informational

Climbs are suspect for double pumps, also slightly slower vertically than dives.

Trying 30 degree upcast.

Created by: dkaragon @ 2016-02-29 14:40:20Informational

Oddities on pump are still high even at 550 m, trying 500 to see if it calms or if flying deep again changed the oil retract rate.

Created by: dkaragon @ 2016-02-26 10:05:38Informational

16 de_pump oddities at 550 m for last segment, will let it go another one since I think fouling is going to be a problem soon.

Created by: dkaragon @ 2016-02-25 10:34:09Informational

Dockserver crashed due to java update? would hang during file transfers. Missed callins likely due to that.

About 30+ hours no communications.

Upon surfacing de_pump oddities went from 41 to 78 the last call in. Roughly 2 segments so about 18 / segment or about 2.3 / yo. Not terrible but not great. Due to circumstances backed off from 600 m to 550 m. We might be able to get away with 575 once we get settled again.

Created by: dkaragon @ 2016-02-24 08:35:30Informational

0, 2 DE_PUMP oddities at 550 for 2 segments

Trying 600 m

Created by: haldeman @ 2016-02-23 10:06:42Informational

Switched to 550 m yesterday. Will need to monitor pump/power performance.

Restarting mission just in case LMC was acting strange as we have had fairly static currents.

New SBDlist with more steering data and less pump data.

Created by: dkaragon @ 2016-01-27 17:08:41Informational

P steering term was cause of poor steering performance, not compass. Compass operating OK.

new SBDLIST.dat, fin over 1 yo and less GPS (hoping for smaller file size) (will need to make sure enough GPS is coming back)

For next segment: CTD on for entire yo, up and down

Created by: dkaragon @ 2015-11-30 16:35:11Informational

Dive velocity a little slow < 10 cm/s (mostly due to pitch angles < 20 deg).

Dive pitch to 24 degrees from 22.

Weak argument for almost 10% fouled at this point in time. Pump currently in a good streak.

Created by: dkaragon @ 2015-11-26 20:07:37Informational

As of previous surfacing, 8 yo's instead of 7.

Created by: dkaragon @ 2015-11-25 09:46:26Informational

Witnessed the pump go from higher slipping to lesser slipping up to 2015-11-25 03:22, could be a clue, perhaps MLG.

Created by: dkaragon @ 2015-11-25 09:38:55Informational

2015-11-25 03:22 surfacing: 22 deg climbs, but 500 m bottom inflection. Oddities were 0 however at this surfacing. Also double pump's not noticed looking at data. Will grab MLG to see what the oddities are.

Created by: dkaragon @ 2015-11-20 16:41:53Informational

6 oddities @ 22 deg upcast

Changed to 26 deg upcast

Created by: dkaragon @ 2015-11-19 16:00:59Informational

For next segment:
New Pitch Angle: 24 deg upcast, still 22 down.

Oddities creeped back up, oil slip rate has increased overall but climbs seem to be most affected.

Science turned back on. (first dive)

Created by: haldeman @ 2015-11-10 19:37:34Informational

Diving to 500 m to see if we can reduce oddities/slippage/power.

Created by: dkaragon @ 2015-11-05 23:02:18Informational

Climbing to 100 vs 125 m

Turned science off to see power savings.

Created by: dkaragon @ 2015-11-04 21:46:24Informational

Power usage is up (pump sliding has increased).

22 deg pitch angle dive and climb @ 4 yo's to try to lower power.

Created by: dkaragon @ 2015-10-31 20:13:59Informational

Pitch deadband is back to default 3 degrees since the last 2 surfacings.

Created by: dkaragon @ 2015-10-29 20:49:37Informational

Changed pump deadband + 10 cc to 70 sensor:f_de_oil_vol_deadz_width(cc)=70

Changed climb to cc from 210 to 220. We are now front limited on positive drive, 220 is the new max.

Created by: dkaragon @ 2015-10-28 17:18:43Informational

-150 to -130 cc for dives (see if power drops)

We are sliding at a faster rate then 2 weeks ago.

Created by: dkaragon @ 2015-10-12 16:38:03Informational

Changed both dive and climb back to +- 26 degrees. Dives were a tad fast. We need to see if oddities increase from this point on.

Created by: dkaragon @ 2015-10-09 21:16:59Informational

Long surfacing, had to take it out of a mission.

Downloaded ru29-2015-279-1-2 MLG. It is just OOD oddities, nothing else.

Power usage looks down, so pitch/pump change may be working. Long surfacing.

Changed SBD to hopefully get more useful m_depth

Created by: dkaragon @ 2015-10-08 20:05:07Informational

Changed pump from -170 to -150 cc, pitch from -26 to -29 (-0.506) deg

Goal is to maintain vertical velocities but to do it with less pump. This will help show that if we pump less oil at depth we will retract some of the power losses.

Created by: dkaragon @ 2015-10-08 19:27:45Informational

ru29-2015-279-1-2 (0218.0002)

High oddities (17) despite deadband change.

Worth MLG download.

Created by: dkaragon @ 2015-10-08 11:10:13Informational

SBD m_depth stopped reporting at 10-20 m. That's not what we need. Going to try just reporting it at surface which is 5 m, hopefully we can see how it climbs then. May add a bit more GPS to SBD too.

Power usage still up, oddities down.

Created by: dkaragon @ 2015-10-07 13:05:50Informational

Changed SBD to add m_depth for 'rising to surface'. MBD command problems (more later).

60 cc DB helped, data only showed 2-3 double pumps with 9 oddities.

Created by: dkaragon @ 2015-10-07 09:09:23Informational

f_de_oil_vol_deadz_width from 30 cc to 60 cc

Changed SBD to more pump data and less steering data.

Created by: dkaragon @ 2015-10-02 21:25:47Informational

Phone call memo Scott
1) de_pump sbd data for full yo, cut back steering
2) MBD MLG from recent segment
3) obtain silbo data on pump oddities / hr

Further tuning:
1) how much oil/sec, increase db to avoid double pumps
2) potentially increase pump volume to compensate for speed loss from oil retraction
3) race pump with pitch angles

Going back to AP dive and climb for pitch angle. Fixed battpos was getting too shallow and steering needs a variable eliminated for troubleshooting.

Lowering dgain from 7.5 to 3 to neuter for a few segments.

Created by: dkaragon @ 2015-08-09 19:25:39Informational

Recently ran upcast for several segments 8/3 onward.

Changed to upcast pitch AP at 26 degrees. Climb angles were getting a little shallow.

u_low_power_hd_fin_ap_dgain derivative gain to 5 from 0

fin_offset of 2 worked well, maybe can go for 0

Created by: dkaragon @ 2015-07-24 19:41:23Informational

Changed fin_offset to 2 degrees from 4. Glider might not need much offset.

Set CTD to sample up and down for 2 segments, then will turn off.
