Part of the world's largest ice shelf is melting 10 times faster than the rest, shedding light on how it might respond to climate change.

Scientists have studied the rates of basal melt, or the melting of the ice shelves from underneath, of individual ice shelves, the floating extensions of glaciers that empty into the sea. 4 minutes to read . You can also see abundant melt ponds on the ice shelf. Prince Gustav Ice Shelf was situated between Trinity Peninsula and James Ross Island. Part of the world's largest ice shelf is melting 10 times faster than expected due to the sea warming around it, research shows. The Ross Ice Shelf is the size of France. The Ross Ice Shelf is a floating slab of ice the size of France, which is located in Antarctica fairly close to the South Pole. 30 Apr, 2019 3:08pm . An international team of scientists conducted an exercise spread out over four years to ascertain how the shelf behaved with the ocean beneath it. The Ross Ice Shelf in Antarctica is melting faster than previously forecast. Most of the grounded glacier ice that is being held back by the Ross Ice Shelf is unlikely to melt anytime soon, in part because it is also held in place by the shape of underlying mountains and valleys, said Padman. A study just published in the Journal of Geophysical Research: Oceans helps to reveal the local factors that influence the Ross Ice Shelf’s stability, refining predictions of how … Ross Ice Shelf, world’s largest body of floating ice, lying at the head of Ross Sea, itself an enormous indentation in the continent of Antarctica.The ice shelf lies between about 155° W and 160° E longitude and about 78° S and 86° S latitude.The current estimate of its area is about 182,000 square miles (472,000 square km), making it roughly the size of the Yukon territory in Canada. Dr Williams said the ice shelf is right up against Ross Island which is a pinning point with the island holding the shelf there. You can see an example from northern Antarctic Peninsula below. The Ross Ice Shelf is a creation of nature. In the Ross Sea, the deep water is cooled by the cold winter atmosphere in a region of open water, called the Ross Shelf Polynya, before flowing under the ice shelf. They ultimately melt due to the surrounding heat and add to the rising sea level. Parts of the world's largest ice shelf are melting 10 times faster than the shelf's average rate, and this could have worrying implications for sea level rise.The finding is part of a study of the Ross Ice Shelf, a block of ice about the size of France, which plays an important role in stabilizing the rest of Antarctica, as BBC News reported.

Massive chunks of ice break away from ice shelves and keep floating away from the source. You can see glaciological structures on the ice shelf, indicating that it flows out from its tributary glaciers. Kiwi scientists have untangled the complex reason why part of the world's largest ice shelf is melting away 10 times more quickly than the rest of it. Melting ice shelves like the Ross could cause seas to rise by several feet over the next few centuries. This has been revealed by an international study conducted by researchers at Cambridge University and the National Institute of Water and Atmospheric Research (NIWA), which analysed the melt rate at the base of the Ross Ice Shelf, the largest Antarctic ice shelf. But this is the first comprehensive survey of all Antarctic ice shelves. The Ross Ice Shelf in Antarctica is freezing, not melting and no one knows why The ice shelf was first found to be warming, but now it seems to have started to freeze. At about 500,000 sq km, Antarctica's Ross Ice Shelf is equivalent to the area of France. RECORDS levels of melting are occurring at the world's largest ice shelf due to the warming sea around it.

Compared with the Amundsen Sea to the east, where a deep current of warm water crosses the continental shelf to cause rapid melting of the ice shelves, little warm water reaches the Ross Ice Shelf. Recent research has found that the ice shelf is disappearing 10 times faster than expected. The Ross Ice Shelf is the largest ice shelf in the world. But the melting corner of the Ross happens to be located right in front of a particularly vulnerable swathe of ice on the continent. Located on the side of Antarctica closest to New Zealand, it spans an area about the size of … If there are really high rates of melt around Ross Island and the shelf disconnects from the pinning point, then Dr Williams said the ice shelf would likely melt very rapidly and carve more icebergs after it detaches. When it comes down to something like this particular ice shelf…
