The upstream swamp canals feed streams with dry areas between the streams which retard flow of the glacier. For this reason, Thwaites is known as Antarctica’s “Doomsday glacier”. The cavities hidden beneath the ice shelf are likely to be the route through which warm ocean water passes underneath the ice shelf up to the grounding line, they said. For starters, its density contains two-feet of potential sea level. Underwater robot reveals hidden base of Antarctica’s ‘doomsday’ glacier. The collapse of this glacier alone would raise the sea level by about 65 centimetres (25 inches). [8] Since the 1980s, the glacier had a net loss of over 600 billion tons of ice though 2017. Dubbed the “doomsday” glacier, Thwaites, perhaps more than any other place in the world, holds crucial clues about the future of the planet. Exceptional sea-ice break up in early 2019 enabled the icebreaker to survey more than 2,000 square kilometers of sea floor at the glacier's ice front. First ever footage of the underside of the 'doomsday' Thwaites glacier has been sent back by a robotic yellow submarine dubbed Icefin. He reports on recent research on the glacier and some of the discoveries. Accessed February 5, 2020. International Thwaites Glacier Collaboration (2020) About the ITGC. [10], In 2020, scientists discovered warm water underneath the glacier for the first time. A photo from Europe's Copernicus Sentinel … Images show massive Antarctic change in just 9 days, Greenland's ice sheet melted faster than ever before in 2019, study says. [13], Extensive calving at the marine terminus of Thwaites Glacier is monitored by remote sensing and seismological observations, with the largest events being seismically detectable at ranges up to 1600 km. Antarctica's "most terrifying glacier" 04:19. Scientists widely consider Thwaites glacier to be the most dangerous block of ice on planet earth. Scientists have found warm water beneath Antarctica's "doomsday glacier," a nickname used because … BBC News Chief Environment correspondent, Justin Rowlatt, visited Thwaites Glacier with scientists from the International Thwaites Glacier Collaboration during the 2019-2020 field season. This hypothesis is based on both theoretical studies of the stability of marine ice sheets and observations of large changes on these two glaciers. Visiting the most vulnerable place on Earth: the 'doomsday glacier', International Thwaites Glacier Collaboration, Antarctica melting: Climate change and the journey to the 'doomsday glacier', "Thwaites Glacier: Antarctica, name, geographic coordinates, description, map", "Time 'Thwaites' for no one: the story behind Thwaites Glacier in Antarctica", "The Race to Understand Antarctica's Most Terrifying Glacier", "Scientists Predict Faster Retreat for Antarctica’s Thwaites Glacier - The Earth Institute - Columbia University", "This Antarctic glacier is the biggest threat for rising sea levels. By Paul Voosen Jan. 28, 2020 , 4:05 PM. Ice draining from the gigantic Thwaites Glacier into the Amundsen Sea in West Antarctica already accounts for about 4% of global sea-level rise, and scientists say it is highly susceptible to climate change. [23][24], In January 2019, NASA discovered an underwater cavity underneath the glacier, with an area two-thirds the size of Manhattan. [15], A 2014 University of Washington study, using satellite measurements and computer models, predicted that the Thwaites Glacier will gradually melt, leading to an irreversible collapse over the next 200 to 1000 years.[16][17][18][19][20][21]. Updated 1619 GMT (0019 HKT) September 9, 2020. A file photo of the Thwaites Glacier in Antarctica, known as the 'Doomsday Glacier'. The find was made possible thanks to an underwater robot called Icefin, which headed more than 700 metres below the ice of the Thwaites Glacier. The high cliffs at the ice front of Thwaites Glacier, which accounts for about 4% of global sea-level rise. The feature was about 112 km long and 32 km wide, and in January 1966 its southern extent was only 5 km north of Thwaites Glacier Tongue. In 2001, a study of Thwaites Glacier using satellite radar interferometry data from the Earth Remote Sensing Satellite 1 and 2 revealed that the grounding line of Thwaites Glacier was retreating at 1 kilometer per year and that the glacier was significantly out of mass balance, hence confirming presumptions of collapse by Terence Hughes, University of Maine, in 1973. They confirm thawing of the Thwaites glacier contributes about four percent of global sea-level rise.
