A first-of-its-kind study looking at surface meltwater lakes around the East Antarctic Ice Sheet across a seven-year period has found that the area and volume of these lakes is highly variable year-to-year, and offers new ...

Underneath Antarctica's vast ice sheets there's a network of rivers and lakes. This is possible because of the insulating blanket of ice above, the flow of heat from within the Earth, and the small amount of heat generated ...

Glacier ice is usually thought of as brittle. You can drill a hole in an ice sheet, like into a rock, and glaciers crack and calve, leaving behind vertical ice cliffs.
