The ice shelves in Antarctica cover 75% of its coastline. They are extremely important as they prevent ice sheets from flowing into the sea. In the map opposite, the ice shelves are highlighted in light orange. As you can see, they fringe all around the coastline of Antarctica. The dark ...
The results indicate that despite catastrophic calvings such as those from the Amery, West, Bellingshausen, and Thwaites ice shelves, involving a total of about 20,000 km2 of ice, the total area of the Antarctic ice shelves during this 20鈥恲ear period increased by 135,000 km2 or by 9 ...

Ocean-driven melting of floating ice-shelves in the Amundsen Sea is currently the main process controlling Antarctica’s contribution to sea-level rise. Using a regional ocean model, we present a comprehensive suite of future projections of ice-shelf melting in the Amundsen Sea. We find that rap...
Map of Antarctica highlighting the major geographic regions, ice sheets, and sites of several research stations.(more) Antarctica, in contrast, hosts the world’s largest present-day ice sheet. The continent is about 14,200,000 square km (5,500,000 square miles) in size, and thick ice cov...
Reductions in the thickness and extent of Antarctic ice shelves are triggering increased discharge of marine-terminating glaciers. While the impacts of recent changes are well documented, their role in modulating past ice-sheet dynamics remains poorly co
During the advance phases of 19471960 and 19651975 the Larsen, Filchner, and Amery ice shelves and the Shirase outlet glacier displayed pronounced surges. Analysis of fluctuations in the major glaciers of West and East Antarctica revealed asynchronous and outofphase elements in their behavior. This ...
break off and become part of the pack ice. A third type of sea ice, known asmarine ice, forms far below the ocean surface at the bottom ofice shelvesin Antarctica. Occasionally seen in icebergs that calve from the ice shelves, marine ice can appear green due to organic matter in the ...
However, we do not know if and how much of the buttressing regions of Antarctica's ice shelves are vulnerable to hydrofracture if inundated with water. Here we provide two lines of evidence suggesting that many buttressing regions are vulnerable. First, we trained a deep convolutional neural ...
