Dropped our little work-boat off, to in-turn drop off an even smaller robot #oceanglider. This is to do buoyancy tests. The team were very well-rugged up. If the tests go ok we'll retrieve the glider and steam south for a few hours then deploy later tonight sending the glider on a 10 day mission to head northwards measuring heat/salt/oxygen flow. #TAN2502 #Antarctica #Oceanography (img: Hana Ishii)

another #OceanGlider is recovered in #TheRossSea - this time the Italian team recovered their vehicle. #OceanRobotics - we now have 3 gliders all returned so can start mapping the system in the days ahead spent sheltering from the next storm

while we discussed recovery options the ship drifted over to the glider - so we actually had to push away from the robot so we didn't go over it. #Oceanography #OceanGlider

so we got our awesome #OceanGlider that could back - #Manaia - it was a nervous juggle getting it to surface away from an advancing field of #SeaIce - all while we were stuck with weather - as it was after a 50 km journey it ended up just being 100 m the right side of a messy band of ice. It would have been quite the pain if it had come up in that chilly soup. #climate #Oceanography #robots

we got this baby into the water off Cape Colbeck late last night - an #OceanGlider - the future of #oceanography. This robot will hopefully run a line of zigzagging up and down measuring ocean temperature (surface temps -1C) and salinity north of here while (i) we do other sampling + (ii) a storm passes over. It has no propeller - it "flies" in the water by changing its buoyancy @ 800 m/hr. Its already sent back a tonne of data. big shout out to Jasmin McInerney who keeps this kit operating
