Glider took on sea water seemingly on last dive at around 120 m. It then triggered a leak at 750 m and came back to 120 m before it became nuetrally buoyany for 3 hours. Weight ejected which got it back to the surface.

Didn't seem to take on much more water at 120 m and at surface the glider stopped calling in around 2 hours later.

Glider was found midday 7/6 off Zoni beach Puerto rico and handed over to UPR personnel. Appeared to be in good shape visually.

If no further notes likely lost power from water ingress.

Set glider to drift and to attempt to transfer mbd's, nbd's, and ad2 files via script. Only got 45kb of one nbd file before the glider hung up for the last time.

RU29 hung up at 2:35am local time, July 1 and never called back.

RU29 is presumed lost.

RU29 aborted ~12am local time, Friday, July 1 with a leak. Fore triggered first, but both aft and forward have water.

Abort happened at 768m on the dive - quick drop in the leak detect readings. There is a little bump in the pressure record at this time too, but only up 0.2m.

RU29 then got stuck on the climb from the abort at 150m, until it shot the weight, and then got to the surface

vacuum has been steadily dropping since surfacing for the abort. Vacuum was 7.9 at first call-in (12am), 6.4 at 2am
