Thwaites Glacier is an unusually broad and vast Antarctic glacier located east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land. It was initially sighted by polar researchers in 1940, mapped in 1959–1966 and officially named in 1967, after the late American glaciologist Fredrik T. Thwaites.
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.

Ice streams are a type of glacier [1] and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System). [2]
Scientists using ice-breaking ships and underwater robots have found the Thwaites Glacier in Antarctica is melting at an accelerating rate and could be on an irreversible path to collapse ...
The edge of the Thwaites Glacier extends into the Amundsen Sea in western Antarctica. NASAThis episode of The Conversation Weekly podcast is about the Thwaites Glacier in Antarctica. Thwaites is ...
Researchers said the entire glacier holds enough water to raise sea levels by more than 2 feet. "Doomsday glacier" ice shelf could shatter within 5 years, scientists say Skip to main content
The Pine Island and Thwaites Glaciers, which both flow into the Amundsen Sea, are two of Antarctica's largest five. Researchers reported that the flow of these glaciers increased starting in the mid-2000s; if they were to melt completely, global sea levels would rise by about 0.9–1.9 meters (3.0–6.2 feet).
The Thwaites Glacier on the vast West Antarctica Ice Sheet is commonly called the "Doomsday Glacier" because of its potential to significantly raise sea levels, inundating low-lying coastal ...
