GPS measurements reveal the flexing movement of one of the ice shelves that act as key backstops to sea level rise
Weddell Sea. Partly aground but mostly afloat, these nearly level ice shelves are from 600 to 4,000 ft (180–1,220 m) thick. They move steadily toward the sea and are fed by valley glaciers, ice streams, and surface snow accumulations. Smaller ice shelves are found all along the coast...
Generally, areas near the center of Antarctica saw small fluctuations, while the West Antarctic Ice Sheet experienced substantial ice loss (shown in dark red) over the fourteen-year period. Floating ice shelves, which are not measured by GRACE, are shown in gray. Video: The mass of the Antar...

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 ...
This story map provides an introduction to one of Antarctica's most important features, its ice shelves. Part 4 of An Introduction to Antarctica The distribution of Antarctica's ice shelves Ice shelves are formed when the ice on the land flows slowly out to sea. Because the water temperatures...
Dense surface patterns are frequent on fast flowing ice masses (ice streams), whereas most ice shelves show a dense surface pattern only close to the grounding line. Flow line analyses on ten ice shelves reveal that the time of residence of the ice along a flow path and-associated with it...
Ice shelves, or ice sheets floating on the sea, cover many parts of the Ross and Weddell seas. These shelves—the Ross Ice Shelf and the Filchner-Ronne Ice Shelf—together with other shelves around the continental margins, fringe about 45 percent of Antarctica. Around the Antarctic coast, ...
Another, Autosub-2, was trapped as it explored life beneath permanent ice shelves around Antarctica in 2005. FromThe Daily Beast They went AWOL all around the world—from the waters around Antarctica to just off a Japanese Island—for a host of reasons. ...
Two countries in the Northern Hemisphere also have ice shelves and they are Greenland and Canada. These shelves form when ice piled on mountains and terrain slides down the coast and into the water. 2The weather is extreme with high winds and normal temperatures between -40 and -90 degrees...
