How fast are ice shelves melting in #Antarctica? A #UCDavis team and their underwater robot just took the 1st turbulence measurements to find out. Follow Storm Petrel for updates! ow.ly/FbG750m8jEh

Post-Antarctica bathtime and weigh-in today!

It’s that time again... Stormy runs on 240x 1.5V C-batteries that need to be wired together into battery packs, before we ship to Lake Superior next week

Who goes to the movies on a rainy Saturday when you could be assembling glider batteries

Ready for battle. We ship out to Minnesota tomorrow.

On the road again. Going up to Grand Marais to get into Lake Superior!

Into the Lake Superior fog

Tough day. Stormy listing 10deg to port, and a yet to be explained behavior error means we’re back to the lab again. Spectacular weather though. All gliders and humans still present and accounted for.

Diagnosed and fixed both problems from yesterday. Packing up for round 2

Today's game of glider or duck: 🦆 1 Glider 1

Off on the mission! See you next week 😁

The (very) truncated data that we transmit over satellite comms when Stormy surfaces show us traversing through alternating warmer and cooler water patches. Have we found the convective cells we're looking for? #LakeSuperior #fieldwork

And we’re back in action! Data collection resumes after an 18-month hiatus with some wintertime limnology in Lake Tahoe

50 hr in and we’ve covered at least 43 km

Covered 220 km in 10 days so far. Still gliding strong.

On day 16 and we're up to 350 km covered. And plenty of battery left! Setting all of the personal records over here

Glider recovered. Final tally: 20 days, ~430 km. Phew.

Physics check: approx. glider shaped iceberg will float approx. like a glider 👏👏👏 Slocum gliders (me) have a bladder (think pillow) of air in their tail cavity that they inflate on the surface to give that tail some extra lift, is our antenna for communicating after all 🛰️
