As snow falls on Antarctica, layers build up and turn to ice. Over time, this compressed snow has become a continent-sized glacier, or ice sheet. It's enormous—almost double the size of Australia and far larger than the ...

Decades before any probe dips a toe—and thermometer—into the waters of distant ocean worlds, Cornell astrobiologists have devised a novel way to determine ocean temperatures based on the thickness of their ice shells, ...

More than merely cracks in the ice, crevasses play an important role in circulating seawater beneath Antarctic ice shelves, potentially influencing their stability, finds Cornell University-led research based on a first-of-its-kind ...

Four dozen Antarctic ice shelves have shrunk by at least 30% since 1997 and 28 of those have lost more than half of their ice in that time, reports a new study that surveyed these crucial "gatekeepers'' between the frozen ...

For most of us, Antarctic sea ice is an abstraction—something far away we may have seen on a documentary. But the radiant white sheets of ice floating on the seas around the snowy continent are a crucial component of Earth's ...

As global ice dams begin to weaken due to warming temperatures, a new study suggests that prior attempts to evaluate the mass of the huge floating ice shelves that line the Antarctic ice sheet may have overestimated their ...

A new model developed by Caltech and JPL researchers suggests that Antarctica's ice shelves may be melting at an accelerated rate, which could eventually contribute to more rapid sea level rise. The model accounts for an ...
