Thwaites Glacier (in white) overlain with a red map of Pennsylvania. About Melt Thwaites glacier: Canyon-sized cavities helping melt ‘Doomsday Glacier’ from inside out September 9, 2020 The Thwaites Glacier in the Antarctic is in danger of … “Because it’s uncertain, Thwaites has the potential to really be the Doomsday Glacier. We find that the stress balance approximations, the friction law, the treatment of ice shelf melt near the grounding line and the ice shelf melt … Thwaites is a massive glacier on the West Antarctic ice sheet. Currently, Thwaites' ice loss contributes approximately 4% to the annual rise in global sea-levels, with the potential to add 65cm in total should the whole glacier collapse. The team studying the Thwaites Antarctic glacier has announced direct measurements of warm water melting it from underneath. The Thwaites glacier has experienced significant flow acceleration since the 1970s. This results in the glacier speeding up, stretching out, and thinning, causing the grounding line to retreat ever further. Icefin has reached the point at which the warm ocean water meets the wall of ice at the front of the mighty Thwaites glacier - the point where this vast body of ice begins to melt. Read More It is known as a marine-terminating glacier, meaning that as snow falls on the glacier and compacts into ice, ice is also flowing out to sea from the front of the glacier. How quickly will Antarctica’s massive Thwaites Glacier melt, and what will that mean for global sea levels and coastal cities? Thwaites glacier melt in Antarctica To understand the intensity of the melting of the Thwaites glacier, researchers inserted Icefin -- a really long yellow robot designed to find alien life on Jupiter’s moon Europa. Thwaites is the most worrying glacier in Antarctica because of its size — it is unusually wide, presenting a 75-mile front of ice to the ocean, without any rocks or mountains to hem it in. Thwaites has been described as one of the world's most dangerous glaciers because its demise could lead to rapid changes in global sea levels. We have a news update from the International Thwaites Glacier Collaboration (ITGC) MELT project. Already, the glacier is responsible for about 4 percent of the world’s rising sea levels, according to a NASA news release. A team of UK and US researchers have found a series of deep channels beneath Thwaites Glacier thought to be acting as pathways for warm ocean water to melt the underside of the ice. The Thwaites Glacier is one of the most dangerous glaciers in the world, and scientists are eager to travel to Antarctica to study it. Thwaites Glacier (75°30′S 106°45′W / 75.500°S 106.750°W / -75.500; -106.750), sometimes referred to as the Doomsday Glacier,[1] is an unusually broad and vast Antarctic glacier flowing into the Pine Island Bay, part of the Amundsen Sea, east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land. From 1992 to 2011, the centre of the Thwaites grounding line retreated by nearly 14 kilometres (nine miles). But it's receding by about half a mile per year. The Thwaites Glacier might one day disappear, but it doesn't spell the end for humanity. If the glacier melts entirely, it could trigger a 10-foot rise in sea levels. If the Thwaites Glacier was to become truly unstable, it would be devastating. The Thwaites Glacier in Antarctica is the size of Britain. Deep channels link ocean to Antarctic glacier September 8, 2020 From the ITGC Newly discovered deep seabed channels beneath Thwaites Glacier in West Antarctica may be the pathway for warm ocean water to melt the underside of the ice. The Thwaites Glacier is on Antarctica’s western coast and is about the size of Florida. Composite image of Thwaites glacier taken on 2 December 2001 (left) and on 28 December 2019. That exposes more of a glacier's underside to seawater, accelerating the melt rate. Antarctica’s Thwaites Glacier has been in the spotlight in recent years, as scientists have undertaken a multi-part international project to study the vast glacier from all angles. And scientists say annual sea level rise has roughly doubled since 1990 — and could worsen if the Thwaites Glacier were to melt. Satellites have shown the glacier changing rapidly, but it’s in such a remote part of Antarctica that it’s difficult to study. We simulate the response of Thwaites Glacier, West Antarctica, to varying model configurations and ice shelf melt scenarios. It’s about the size of Florida and accounts for nearly 4% of global sea level rise, a contribution that has doubled since the 1990s. The long device was slid 600 metres deep into the. The Thwaites glacier is larger than England, Wales and Northern Ireland put together THWAITES GLACIER OFFSHORE RESEARCH Just last month, the last fully intact ice shelf in … The Thwaites Glacier is one of the epicenters of this rapid deterioration. Before we get into it, let’s do a quick The glacier terminus is nearly 120 km wide, and the bed of the glacier reaches to >1000 m below sea level. Researchers recently spent several weeks studying Thwaites as part of a five-year, international effort to try to answer those pressing That exposes more of a glacier’s underside to seawater, increasing the likelihood it will melt faster. The urgency stems from observations and analyses showing that the amount of ice flowing from Thwaites—and contributing to sea level rise—has doubled in the span of three decades. Pine Island Glacier and Thwaites Glacier together account for 3% of grounded ice-sheet area 1. Thwaites is like the cork in the wine bottle for the rest of the West Antarctica ice sheet. Thwaites Glacier Facts The Science Our People Culture, Diversity & Inclusion Videos: ITGC Explained Projects DOMINOS GHC GHOST MELT PROPHET TARSAN THOR TIME SCO Projects Overview International Partners News & Events Program News Thwaites Glacier is roughly the size of UK (176 x10 3 km 2). But researchers still don’t know exactly how much of the glacier will melt or when, which makes it difficult to know if the ice sheet sitting beyond Thwaites will wash away, too.
