'Poised to disintegrate': Antarctica's '#DoomsdayGlacier' is set to lose its #IceShelf this year
#WestAntarctica's "Doomsday Glacier" is on the brink of losing its ice shelf, further compromising the already melting ice mass and threatening to unleash devastating sea-level rises.
By Patrick Pester
"A vital ice shelf is about to break away from Antarctica's "Doomsday Glacier," further destabilizing one of the world's largest and most vulnerable glaciers.
The #ThwaitesGlacier is nicknamed the "Doomsday Glacier" because its collapse would send so much ice into the Southern Ocean that #GlobalSeaLevels would rise by 2.1 feet (65 centimeters or 26 inches), flooding coastal communities worldwide. This collapse could take centuries, but there is an imminent threat to Thwaites' eastern ice shelf, which will likely accelerate the glacier's demise.
"Researchers say that satellite images reveal that the Thwaites eastern ice shelf is about to detach from the glacier, New Scientist reported last week. While the glacier sits on land, the ice shelf is a floating body of ice that is attached to the glacier's mouth. Researchers still have a lot to learn about the glacier, but this shelf acts as a buttress, restraining the flow of ice from the glacier into the sea."
[...]
"Thwaites Glacier's slow collapse is part of a wider concern among scientists for the future of the West #Antarctic ice sheet. Thwaites is a key pillar of the ice sheet, protecting other ice from slipping into the ocean. If the whole ice sheet were to go, sea levels would rise by 10.8 feet (3.3 m), according to the British Antarctic Survey. The collapse of ice sheets like this one are considered tipping points, or 'points of no return,' in the fight against climate change — meaning that once they are crossed, they bring about permanent changes that cannot be reversed for many thousands of years."

Tides Widen Ice Cracks
When icebergs calve off of Arctic and Antarctic coastlines, it affects glacial flows upstream as well as local mixing between fresh- and seawater. A recent study points to ocean tides as a major factor in widening the ice cracks that lead to calving. The team built a simplified mathematical model of an ice shelf, taking into account the ice’s viscoelasticity, local tides, and winds. Then they compared the model’s predictions with satellite, GPS, and radar data of Antarctica’s Brunt Ice Shelf, where an iceberg the size of Greater London broke off in 2023.
Between their model and the observation data, the team was able to show that the crack that preceded calving consistently grew during the spring tides, when tidal forces were at their strongest. The work gives us one more clue for refining our predictions of when major calving events are likely. (Image and research credit: O. Marsh et al.; via Gizmodo)

Ponding on the Ice Shelf
Glaciers flow together and march out to sea along the Amery Ice Shelf in this satellite image of Antarctica. Three glaciers — flowing from the top, left, and bottom of the image — meet just to the right of center and pass from the continental bedrock onto the ice-covered ocean. The ice shelf is recognizable by its plethora of meltwater ponds, which appear as bright blue areas. Each austral summer, meltwater gathers in low-lying regions on the ice, potentially destabilizing the ice shelf through fracture and drainage. This region near the ice shelf’s grounding line is particularly prone to ponding. Regions further afield (right, beyond the image) are colder and drier, often allowing meltwater to refreeze.

Researchers were working off the coast of #Antarctica when it happened: A gigantic #iceberg about 19 miles long cracked off the #IceShelf on Jan 13, revealing a swath of #ocean that had not seen daylight in decades.
The team aboard a #research vessel called the Falkor (too) decided to search the seafloor under the freshly exposed ocean. No human had ever explored the deep sea there before.

Researchers were working off the coast of #Antarctica when it happened: A gigantic #iceberg about 19 miles long cracked off the #IceShelf on Jan 13, revealing a swath of #ocean that had not seen daylight in decades.

#Thwaites Eastern #IceShelf nearing collapse as cracks spread, not because of melting
These findings and further computer modeling suggest that, while warm #ocean waters are preconditioning ice loss in West #Antarctica, the ongoing internal destabilisation now poses the greatest threat to the Thwaites Eastern Ice Shelf. The ice shelf is in its final phase of disintegration as these cracks grow, independent of melting from below.

'Warm water' from #deepsea flowing towards one of #Antarctica's largest #iceshelves
Antarctica's Filchner-Ronne #IceShelf may be under threat due to relatively warm water from the deep sea flowing towards the shelf.
The melting of a massive ice shelf like FRIS would ultimately lead to huge #sealevelrise. However, researchers still have a lot to learn about this region, and it's unclear whether the increased flow of warm water is linked to #climatechange.
