In 2024, research indicated that instead of a relatively narrow grounding line which separates the parts of the glacier exposed to water and those safely behind them, there is a wider grounding zone of 2–6 km (1.2–3.7 mi) which is regularly exposed to water. Some areas of the glacier are additionally exposed to meltwater flowing another 6 ...
Some named Antarctic iceshelves. Ice shelf extending approximately 6 miles into the Antarctic Sound from Joinville Island. An ice shelf is "a floating slab of ice originating from land of considerable thickness extending from the coast (usually of great horizontal extent with a very gently sloping surface), resulting from the flow of ice sheets, initially formed by the accumulation of snow ...
Scientists have long known Florida-sized Thwaites was vulnerable, in part because of its geography. The land on which it sits slopes downwards, meaning as it melts, more ice is exposed to ...
The Thwaites Ice Shelf is one of the biggest ice shelves in West Antarctica, though it is highly unstable and disintegrating rapidly. [2] [3] Since the 1980s, the Thwaites Glacier, nicknamed the "Doomsday glacier", [4] has had a net loss of over 600 billion tons of ice, though pinning of the Thwaites Ice Shelf has served to slow the process.

The Antarctic Ice Sheet is drained to the sea by several ice streams. The largest in East Antarctica is Lambert Glacier.In West Antarctica the large Pine Island and Thwaites Glaciers are currently the most out of balance, with a total net mass loss of 85 gigatonnes (84 billion long tons; 94 billion short tons) per year measured in 2006.
The glacier has been an important consideration for scientists trying to make predictions about global sea level rise. Seafloor images shed new light on Thwaites Glacier retreat Skip to main content
An ice divide is the boundary on an ice sheet, ice cap or glacier separating opposite flow directions of ice, analogous to a water divide.Ice divides are important for geochronological investigations that use ice cores, since such coring is typically made at highest point of an ice sheet dome to avoid disturbances arising from horizontal ice movement.
Daily tides stoked with increasingly warmer water ate a hole taller than the Washington Monument at the bottom of one of Greenland's major glaciers in the last couple years, accelerating the ...
