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 ...
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. [5]
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 ...
New research on Antarctica's rapidly melting Thwaites Glacier is providing some of the clearest insights yet into how the ice shelf is thinning from below. Scientists take a peek below Antarctica ...
This includes sea ice, ice on lakes or rivers, snow, glaciers, ice caps, ice sheets, and frozen ground (which includes permafrost). Thus, there is a overlap with the hydrosphere. The cryosphere is an integral part of the global climate system. It also has important feedbacks on the climate system.
Scientists have looked back in time to reconstruct the past life of Antarctica’s “Doomsday Glacier.” Their findings give an alarming insight into future melting
A glacier is a persistent body of dense ice, a form of rock [2]) formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers.
