Workers in safety gear on a ship are recovering an submersible, in a misty ocean setting.

New research from our @ueaenv.bsky.social reveals that the speed of ocean currents and the shape of the seabed influence the amount of heat flowing underneath Antarctic ice shelves, contributing to melting.

Ocean submesoscales as drivers of submarine melting within Antarctic ice cavities - Nature Geoscience Submesoscale ocean features deliver heat beneath Thwaites Ice Shelf and contribute to submarine melting, according to numerical modelling combined with available observations.

Antarctica Is Changing Rapidly. The Consequences Could Be Dire “Abrupt changes” threaten to send the continent past the point of no return, at which point continued ice-melting would submerge coastal cities around the world.

“It’s the choices that we’re making right now, and this decade and the next, for greenhouse gas emissions that will set in place those commitments to long-term change.” #climateemergency #antarctica #sealevelrise #seaice #iceshelves #penguins

Brief communication: Sensitivity of Antarctic ice shelf melting to ocean warming across basal melt models Abstract. The uncertain sensitivity of Antarctic ice shelf basal melt to ocean warming strongly contributes to uncertainties in sea level projections. Here, we explore the response of five basal melt ...

Looking for #holiday #science reading?
Our paper with E. Lambert finally came out a few weeks ago. We investigate the sensitivity of ice-shelf melt to ocean warming in different basal melt models.
Spoiler (or not): it varies a lot!

Antarctic glacier found 'stealing' ice from neighbor in rapid shift • Muser Press West Antarctic glacier observed stealing ice from neighbour. Research has revealed that this dramatic glacial theft has occurred over less than 18 years

Scientists observed “ice piracy” in #Antarctica - one glacier stealing flow from another in under 18 years. Study in 'The Cryosphere' shows rapid ice shifts could reshape sea level predictions. DOI: doi.org/10.5194/tc-1... #Glaciers #IceShelves 🧪🧊

The sun was out, the snow stopped, and the temps made it all the way up to 20 so of course it was time to head to the beach! I took the drone up to check out the ice on Lake Michigan.

When the Ice is Gone by Paul Bierman. A very readable history of the Greenland ice sheet with a clear explanation of how easily it could disappear and what that means for our future.

Come for the writing, stay for the science. Can't recommend enough. #Greenland #Iceshelves #Climate #ClimateScience #ClimateChange #Geology

✊ Protecting ice shelves starts with reducing global carbon emissions and advocating for bold climate action. Every fraction of a degree counts when it comes to stabilizing these icy giants!

One of the coolest field missions in @OceanIceEU is Gothenburg University's UAV Huginn, that swims under #Antarctica's #IceShelves
Devastatingly, Huginn did not return from it's last mission...

Staying in #Antarctica + #IceShelves Stina Wahlgren of Gothenburg University showed some cool results from the Huginn AUV, which mapped the underside of Dotson ice shelf, revealing interesting scoops and swirls in the structure, interesting for @OceanIceEU@fediscience.org models to consider
