Ocean heat forced West Antarctic Ice Sheet retreat after the Last Glacial Maximum - Nature Communications Amundsen Sea records show warm Circumpolar Deep Water drove major West Antarctic Ice Sheet retreat from 18,000–10,000 years ago. Subsequent cooling stabilized the grounding line, indicating ocean heat...

🧪🌊🧵 Great to see this published. An 18,000 year record of deep water temperatures on the Amundsen Sea continental shelf, which confirms that incursion of warm water onto the shelf has been the main driver of West Antarctic Ice Sheet retreat throughout deglaciation.

Antarctic Ice Sheet Has Lost a Connecticut-Sized Amount of Ice Over the Past 30 Years - Eos A new study of Antarctica has found that since 1996, its ice sheet has lost 12,820 square kilometers (nearly 5,000 square miles) of ice—nearly enough to cover the state of Connecticut, or 10 cities th...

Over the past three decades, Antarctica has lost nearly 5,000 square miles of ice, mostly in its unstable western region.

Rain is coming to Antarctica – here’s how it will change the frozen continent In the Antarctic Peninsula, precipitation is increasingly falling as rain rather than snow, with consequences for glaciers, penguins and even scientists.

These South Pole Seismometers Will Detect Vibrations 1.5 Miles Under the Ice - Eos The instruments will freeze into Antarctica’s ice sheet, where they will collect detailed, global-scale seismic data.

Right now, two seismometers are slowly freezing into the Antarctic Ice Sheet, housed in boreholes that extend a mile and a half below the surface.
