Lithium post recovery analysis:

136 AH used by glider
Cells were about 3.65 AH / 10.08 AH -- (if we account for SD rate @ .3%/day then we had about 4 AH/cell at recovery (this note about 30 days past recovery)
4 AH remaining thus about 6/10 burned for mission --> 6 * 23 = 138 AH roughly matching glider. If we didn't account for SD rate it would be about 146 AH used

Thus glider reads 1 to 7% lower than batteries. Fairly good agreement as it might be more towards the 1% than 7%.

With 10% remaining on cells as a buffer, about 1 AH we had a remaining 2.65 AH on these cells. 2.65 * 23 = 60 AH. 136 + 60 = 195 total AH.

Likely optode errors, u4stalk failed at surface.

Should try again in a few days. Right now disabled in proglets.dat

Sending back on to shelf before south. Strong currents and other reasons.

pH line to shelf break complete. Deployment being shared between pH and Hurricane projects. Switching over to hurricane triangle now.

f_battpos_db_frac_fz .75 from .5

.5 guess is no good, noticed some pitch oddities

Should look to see why its .5, or if that is normal?

loaded mission ru30.mi

Optode, CTD, FLBBCD all off at surface now. pH on at surface

Back to normal swimming.

Thruster had an error on deck, < 20% might be too little? Seemed to work on test missions.

Rosette cast:
the8x3_filename: 03460000
full_filename: ru30-2019-287-2-0
NBD downloaded from that segment

0345 was shallow mission, 47, 48 were thruster test missions

4 hour mission to 10 m below to cross shipping lanes.

Deployed by Nicole Waite, Grace Saba, Chip Haldeman, & OMDA class out of Morgan Marina aboard RV RUTGERS.

CTD used was 1383 pumped SB19 on SB55 Rosette Nisky Sixx (segment 03460000) for comparison and pH water samples.

CTD 1645 pumped was used with first shallow mission (segment 03450000) for CTD comparion and profile to pick pH water sample depths.
