Robotic underwater vehicle snaps first images seafloor beneath Antarctica Thwaites Glacier
2020/2/20
During the first study of the ocean floor beneath Antarctica’s Thwaites Glacier, scientists took images of the glacier's foundations. Thwaites now accounts for about 4% of global sea level rise, and r...

The Antarctic Circumpolar Current is the planet's most powerful and arguably most important current. It is the only current to flow clear around the globe without being diverted by any landmass.It con...
Antarctic researchers from Rice University have discovered one of nature’s supreme ironies: On Earth’s driest, coldest continent, where surface water rarely exists, flowing liquid water below the ice ...
Three recent publications by early career researchers at three different institutions across the country provide the first look into the biogeochemistry, geophysics and geology of subglacial Lake Whil...
