Latest Antarctic ice sheet Stories
The Antarctic Peninsula has warmed rapidly for the last half-century or more, and recent studies have shown that an adjacent area, continental West Antarctica, has steadily warmed for at least 30 years, but scientists haven't been sure why.
WASHINGTON, March 15, 2011 /PRNewswire-USNewswire/ -- Researchers and flight crew arrived in Thule, Greenland, on Monday, March 14, for the start of NASA's 2011 Operation IceBridge, an airborne mission to study changes in Arctic polar ice.
Ice sheets have been losing mass at an accelerated rate over the past two decades, and these changes could soon become the dominant contributor to rising global sea levels, a NASA-funded study has discovered.
The contribution of Greenland to global sea level change and the mapping of previously unknown basins and mountains beneath the Antarctic Ice Sheet are highlighted in a new film released by Cambridge University this morning.
Scientists have previously shown that West Antarctica is losing ice, but how that ice is lost remained unclear.
Scientists returned this week to the Southern Hemisphere where NASA's Operation IceBridge mission is set to begin its second year of airborne surveys over Antarctica.

GREENBELT, Md., Sept. 1 /PRNewswire-USNewswire/ -- Operation IceBridge - a NASA airborne mission to observe changes in Earth's rapidly changing polar land ice and sea ice - is soon to embark on its fourth field season in October.
A tiny marine filter-feeder, that anchors itself to the sea bed, offers new clues to scientists studying the stability of the West Antarctic Ice Sheet â€“ a region that is thought to be vulnerable to collapse(1).
Antarctica may not be the world's largest landmass -- it's the fifth-largest continent -- but resting on top of that land is the world's largest ice sheet.
Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...
