Deployment ru26d-20190905T1802
Pilot Notes
Apologies for the confusion/glider lingo. Regarding the density finding. The water density has increased by .6 sigma since deployment which is about 40 g of buoyancy. An example of a plot we use to monitor fouling tracks vertical velocity over time corrected for pitch and buoyancy: https://marine.rutgers.edu/~dkaragon/glider_profile_plotting/ru26d/ru26d_VerticalVelFouling.png From that we can see dive and climb speeds have diverged about 2.5 cm/s showing a possible increase in glider mass by about 16 g. So our net says about 40 + 16 = 55 g weight gain since deployment. May share that with company and see how much fouling is actually on it. 55 g is a decent amount. Just an interesting finding that is hard to see in other places we fly because of much larger density changes over time. POST RECOVERY WEIGH PARTS AND REMEASURE DENSITY, MAYBE EMAIL TWR OR NOC
