This is a list of Antarctic ice shelves. An image of Antarctica differentiating its landmass (dark grey) from its ice shelves (minimum extent, light grey, and maximum extent, white) Edge of Ekstrom Ice Shelf. Ice shelves are attached to a large portion of the Antarctic coastline.

Ice shelves are found in Antarctica and the Arctic (Greenland, Northern Canada, and the Russian Arctic), and can range in thickness from about 100–1,000 m (330–3,280 ft). The world's largest ice shelves are the Ross Ice Shelf and the Filchner-Ronne Ice Shelf in Antarctica.

2020年6月22日 · Ice shelves surround 75% of Antarctica’s coastline, and cover an area of over 1.561 million square kilometres (a similar size to the Greenland Ice Sheet). Ice shelves gain mass from ice flowing into them from glaciers onland, from snow accumulation, and from the freezing of marine ice (sea water) to their undersides [1].

11 小时之前 · Surface melting for the Antarctic ice sheet appears to have set a record for the 46-year satellite observation period on January 2, 2025. All areas of the Antarctic coast that generally see significant summertime melting continue to accumulate melt days at a faster-than-average pace, except along the northern West Antarctic ice shelves, which are now near-average.

The largest ice shelves, as big as Texas or France, are located in Antarctica, but some unusual ones also occur in the Arctic. One example of an ice shelf made up of compacted, thickened sea ice hundreds of years old is the Ward Hunt Ice Shelf off the coast of …

2022年8月18日 · The Antarctic continent is surrounded by ice shelves. They cover >1.561 million km 2 (an area the size of Greenland)[1], fringing 75% of Antarctica’s coastline, covering 11% of its total area and receiving 20% of its snow.

Ice shelves end at the continental edge, where the ice calves off to form ice bergs. These areas of floating, fresh-water ice (formed from snow accumulation) are attached to the major ice sheets that cover Antarctica. Ice shelves are in contact with the atmosphere above, and the ocean below.

Ice shelves are the floating extension of the Antarctic ice sheet as it pushes out over the ocean. As snow accumulates on the continent, its weight compresses to form glacial ice, which slowly pushes the ice sheet seawards. Ice shelves may be hundreds of …

This polygon shapefile depicts year-round ice shelves and ice tongues in Antarctica. Data does not include seasonal sea ice which extends much farther around the entire continent, and that can vary considerably day to day.

2024年2月21日 · We show that only small localized pockets of ice shelves were thinning between 1973 and 1989, located primarily in the Amundsen Sea Embayment and the Wilkes Land coastline. Ice-shelf...
