Switched to downcast only AZFP Sat night EST, no change in power consumption. Latest .azf looked good though (transferred it).

Turning off file transfers to avoid Gould.

Ice moved in, staying south. Optics off past 200 m.

u_alt_reqd_good_in_a_row 6

Created by: dkaragon @ 2019-01-14 13:02:25Informational

Trying u_alt_reqd_good_in_a_row 5 from 4.

Getting enough hits on actual bottom, likely need that set to 6 or 7 to get through krill layers but that's a big change so going to have to test it incrementally.

Had a bottom sample at 65 m in 150+ m (according to bathy). Have to back off altimeter settings to

!!!! 50 m !!!!!! alt/water limits

Increasing from 3 to 4 pings for bottom to try to punch through krill? layers better. May have to increase it further to 5 or 6 before see any difference but want to make sure real bottoms still have time. By setting m_water_depth yo lifetime to 0 it effectively disabled flying by m_water_depth which may be good in this case for avoiding krill.

Alkaline C 1400 nominal = 7.8 AH
To 1.0 (10 V) about 80% --> 6.2 AH
Taking average of different companies has 0C for alkalines at about 15-25% derating (much better at less draw than at high draws)

ru32 has 23 * 6.2 = 143 AH @ 20C
~ 115 AH @ 0C

We should record the H moment on this glider (it might be 10'ish from measurents prior to Eager) but its maximum angles are +- 23-24 degrees at full pump.

Shallow upcast dangerous in Antarctica might need some flotation on this glider for next year.
