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 ...
Scientists using ice-breaking ships and underwater robots have found the Thwaites Glacier is melting at an accelerating rate and could be on an irreversible path to collapse.
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 ...
The Thwaites Ice Shelf is one of the biggest ice shelves in West Antarctica, though it is highly unstable and disintegrating rapidly. [23] [24] Since the 1980s, the Thwaites Glacier, nicknamed the "Doomsday glacier", [25] 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 outlook for "Doomsday Glacier" just got gloomier. Scientists are warning the Antarctic Ice Sheet, known formally as the Thwaites Glacier, will deteriorate "further and faster" and that sea ...
[20] [21] [22] The Thwaites Glacier alone, in Western Antarctica is "currently responsible for approximately 4 percent of global sea level rise. It holds enough ice to raise the world ocean a little over 2 feet (65 centimeters) and backstops neighboring glaciers that would raise sea levels an additional 8 feet (2.4 meters) if all the ice were ...
Basal channels are distributed into three main categories by how and where they are formed relative to an ice shelf's grounding line: ocean-sourced channels, subglacially-sourced channels, and grounding-line sourced channels. [1] The grounding line is the point where an ice sheet or glacier meets the ocean and begins floating, forming an ice shelf.
Although the glacier is replenished through snowfall, and glaciers generally accumulate more snow than they lose, the Thwaites Glacier is losing around 50 billion tons more ice than it is ...
