1.25 AH/day = SILBO
1.62 AH/day = RU29 when corrected to match silbo as best as possible (couldn't fly EXACTLY like Silbo due to density near surface)
Going to 4 series is about 77% the cost of 3 series or a savings of 23%. Close to the .75 nominal just from voltage. In other words there is barely any efficiency gains at lower voltage? I think that rumor may be dead now?
predicting 4 series EOL from 3 series means ~ 850 AH total, take off 60 for safety margin (drift, EOL) so lets just use 800 AH
4 series 800 AH is equivalent to ~ 1000 AH 3 series
391 day 3 series would become ~460 days. Additional 2 months

Shortening up SBD file to stay off surface.
Downcast only CTD, will shorten TBD and reduce power.
Back to 950 m dives. Glider voltage looked fine. Looked like a reset hiccup at 700m caused the undervolts. Back to 11 V nominal.
Couple pitch motor oddities and science_super worth looking into post-recovery.

Turned off science low power (-1). Surfaced with sci logging bug just now.
Changed SBD to smaller for single yo profiling.
3 yo's to get us close to RAMA
Switching to single yo's for AM surfacing.
Changed SBD back to a little smaller for time being (no time to analyze it).
Changed surface pitch angle to 30 degrees.
Tested waypoints near, across, on equator, no apparent issues. Tried quadrants around 0N90E
Changed surfac10.ma surface thrust limit from 10 cm/s to 7.5 cm/s to better see how its climbing.
Changed SBD again. More thruster data to better learn the final ascent.
Turned off 'thrust until air bladder inflated'

Upcast sampling turned back on, NOT surface yet.
Since the last note we have been sampling just downcasts and no surface.
Downcast only sampling starting last night. Testing to see if sci logging bug eases up.
Science turned off for the night.
No logging bug on this last surfacing.
Will try just downcasts tomorrow morning.

Science logging error prevalent now. Not sure if related to surface settings (sampling at surface, reduced u_reqd_depth_at_surface etc. Modified script on the fly has been failing, glider has had several long 30+ min surfacings.

Changed surfac10 (nothing commanded) from 420 sec surfacing to 540. Sci logging bug was being triggered and there wasn't enough time to correct it. We had 2nd sci logging bug error just happen.

Looked at DBD from previous mission: 125 m oil flow rate is roughly 6.9 cc/s
SA to ascension it was roughly 6.4 cc/s at 125 m
Glider aborted for sci logging --> beh abort, sat in gliderdos, total surfacing around 25 min. Script didn't catch it, likely because of disconnect, need to look into why script didn't catch.
Post-RU29 meeting; changing waypoint to 7 S, 96 E. Also changing top inflection depth to 200 m.
175 m top inflection, from 150 m
Strange GPS hiccup 2 surfacings ago. DR location looked right, reported currents right, but wrong based on accepted GPS position, see below. Wasn't able to come up with what happened, emailed TWR to alert.
(argos shows glider is 'on track', red square in GE image)
DR Location: -1209.371 N 9857.802 E measured 367.649 secs ago
(this one is right, glider DR was working OK)
GPS TooFar: -1216.096 N 9859.563 E measured 43.688 secs ago
GPS Invalid : -1216.096 N 9859.563 E measured 68.913 secs ago
GPS Location: -1216.096 N 9859.563 E measured 64.124 secs ago
(need to check what our max water speed is but according to masterdata
about 11 km/hr is rough speed so at 13 hours were looking at over 100 km radius
for gps too far, certainly not seeing that there, distances are less than 15 km)
Reset underwater. Missed early call in; caught it 1 a.m. Loadmission ru29.mi; sequence 1k_n.mi(5) Will monitor tomorrow.
Changing top inflection depth to 150 m from 100 m as of next surfacing
1st thruster climb segment:
ru29_2017_004_2_97
Result- thruster working
40% thruster = 25 - 30 cm/s climb
power increase - near negligible
Will try another segment to confirm the power result
surfac10.ma ready to go to turn thruster back off at next surfacing (NOT copied to .cur.ma as of yet)
Thruster test commencing tonight; 40% power for top 100 m when surfacing. Will add original surfac after this one has transferred.
Back into low power mode and *almost back to first down last up sampling.
Sampled 1st and 4th yo full yo, low power mode off for the passing tropical storm. Ran this way for about 48 hours.
Transferred no header initial and lastgasp.mi missions.
