(CNN)Deep channels discovered under the Antarctic's so-called "Doomsday glacier" may be allowing warm ocean water to melt the underside of ice, according to scientists collecting data from an area crucial to understanding sea-level rise. Flowing off the west of the Antarctic continent, Thwaites is almost as big as Great Britain. Thwaites is almost as big as Britain. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. Glaciers are huge sheets of ice moving very slowly, and contain vast amounts of water. (*) To give reasons for a scientific exploration. How quickly could a massive Antarctic glacier collapse? A simpler solution would be to "tackle climate change.". Pine Island Glacier drains much of the marine-based West Antarctic Ice Sheet, and it has a configuration susceptible to rapid disintegration and recession. This isn’t an easy task. It is expected that the entire enterprise will take 3-4 days to complete. Recover your password D … (*) The water under it is very clean. Educational #infographics, information leaflets and interactive tool are available at #ThwaitesGlacier #education page 29. Why are Some Glaciers Blue? Credit: NASA/James Yungel. Thwaites glacier, which is part of the west Antarctic ice sheet, has lost an estimated 540bn tonnes of ice since the 1980s. (*) To drill a hole in the ice. To reach Thwaites glacier before the scientists. "And so, that's why Thwaites becomes really important because it could be a real, turbo-charging effect for how fast sea level rises around the world." “[Thwaites], we think is being affected more by what's happening on the underside, so the heat that's being brought in from the ocean, from the circumpolar deep water,” Pettit said. TOEIC Reading Comprehension Exercises Part 7 is waiting for you! But satellite monitoring indicates this glacier is melting at an accelerating rate. But recent measurements show that the melting of the glacier … It’s a majestic sight, with its buoyant front, or “ice shelf”, pushing far out to sea and kicking off huge icebergs. Scientists predict its ice sheet may break off, increasing sea levels. It is a majestic sight, with its blossoming façade, or “ice shelf,” as it rushes away into the sea and sets off huge icebergs. Once that melts, we are looking at a 10 to 13-foot push of sea into places like New York and Miami. That's worrying news for coastal cities. (*) To reach Thwaites glacier before the scientists. As the glacier withdraws, more ice appears, and as the surface part of each of these ice layers that appear gets bigger, it … The US research ship at the ice front, in a photo captured from a drone.

Thwaites Glacier in Antarctica flows over mountains that stick out of the overlying ice. Once scientists can demonstrate the expected sea-level rise relating to West Antarctica, he said, they will have more evidence when calling for action to mitigate climate change. "At the end, we will be able to say to governments and policy-makers, this is what's going to happen ... we will actually have a proper, well-constrained estimate of what's going to happen to Thwaites Glacier," said Jordan. If one goes, they could all go – and that chain-reaction would raise sea levels by an additional 8 feet (2 metres). The big issue is that there are ice sheets in the Thwaites Glacier that are grounded below sea level, so it’s … (*) The glacier is expected to melt in 3-4 days. The team collected data from the glacier and adjoining Dotson and Crosson ice shelves from January to March 2019. The Thwaites is a very inhospitable place. 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. Find out why this is so important to unlocking how rapidly the glacier might disappear. The 3.5 metre-long icefin carries HD cameras, sonar, and instruments for monitoring different properties of the water, such as the flow, salinity, oxygen and temperature. To give a detailed description of Thwaites glacier. The topography beneath Thwaites Glacier, above, is largely below sea level and slopes inland. The area surveyed had been hidden beneath part of the floating ice shelf extending from Thwaites Glacier, which broke off in 2002, and was then often inaccessible due to thick sea-ice cover.

The more dense a glacier is, the more blue it appears. [Image: Jemma Cox and David Vaughan] What seems to be taking place is that deep warm ocean water is streaming to the coast and down to the ice front, thawing the ice structure. Read More. The important takeaway here is that Thwaites will melt to a point that the glacier will collapse. Ice acts like a protective cover over the Earth and our oceans. If the entire Thwaites Glacier melted, that would result in a worldwide sea-level rise of 1.64 feet, according to the recent study (though another study estimated the rise to be closer to 2 feet).. It's a giant mass of more than 192,000 square kilometers (74,000 square miles) -- … Thwaites is remote, even by Antarctic standards. Why is Thwaites Glacier important? "Thwaites Glacier itself is probably one of the most significant glaciers in West Antarctica, because it's so large, because we can see it's changing today," Dr. Tom Jordan, an aero-geophysicist at BAS who led the airborne survey, told CNN. Thwaites glacier, which is part of the west Antarctic ice sheet, is thought to have lost more than 500bn tonnes of ice in a period of roughly four decades.

By Sam Ellis Jul 14, 2020, 2:10pm EDT 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. What is Thwaites Glacier and why is it so important? Why is the melting of the cavity so alarming? So some other scientists think that if the entire Thwaites glacier were to collapse, it could destabilize surrounding glaciers on the Antarctic ice sheet as well. The big issue is that there are ice sheets in the Thwaites Glacier that are grounded below sea level, so it’s exposed to relatively warm seawater from below. Thwaites glacier is extremely hard to reach, which means that it took weeks for the researchers to get their equipment to the drilling spot. From 1992 to 2011, the centre of the Thwaites grounding line retreated by nearly 14 kilometres (nine miles). These bright white spots reflect excess heat back into space and keep the planet cooler. (*) The “icefin” submarine is very fast. (*) Its melting poses a big threat to the planet. The Thwaites glacier covers more than 74,000 square miles (192,000 square kilometers) and is more than 900 miles (1,500 km) from the nearest U.S. and British Antarctic research bases - so … Anandakrishnan also gives a sense of what it is like to visit Thwaites, one of the world’s most remote places: Source: Wikipedia. Not every thing that changes dramatically, or has the potential to do so, is solely or mainly … Before now, he said, the ITGC has not been able to precisely quantify sea-level rise in West Antarctica "because there was so much uncertainty about understanding the ice sheet processes and how the glaciers will over time respond.". The high cliffs at the ice front of Thwaites Glacier, which accounts for about 4% of global sea-level rise. (*) There is a submarine stuck beneath it. And once it starts to retreat, it will just keep retreating.". Thwaites Glacier in Antarctica flows over mountains that stick out of the overlying ice. A Its melting poses a big threat to the planet. Deep channels discovered under the Antarctic's so-called "Doomsday glacier" may be allowing warm ocean water to melt the underside of ice, according to … At 74,000 square miles, the Thwaites Glacier covers an area the size of Florida or Great Britain.

The glacier is expected to melt in 3-4 days. Why is Thwaites Glacier so important, and how are scientists investigating it? (*) There is a 600-meter hole in it. Over the past three decades, the rate of ice loss from Thwaites, which is about the size of Great Britain or the US state of Florida, and its neighboring glaciers has increased more than five-fold. Why is Thwaites Glacier so important? Jordan said the next phase was to incorporate the data from the channels, some of them 2,600 feet (800 meters) deep, into simulations of how the ice sheet will respond into the future. "I think this is a big step towards helping understand that," he added. The Thwaites Glacier is the largest, most menacing source of rising sea levels all over the world, and it is melting at an alarming rate. Jordan said that suggestions of geoengineering and blocking the channels is not logistically feasible at such a remote site. Because as important as Thwaites is to coastal cities from Miami to Mumbai, few people have ever set foot on the glacier, and until now, no one had ever sailed along its face. Jeff Goodell of Rolling Stone magazine reports on why mapping the sea floor in front of Thwaites glacier is so important.
