Massive crack in Antarctica's Larsen C ice shelf is widening

Scientists have been monitoring a massive crack in one of Antarctica's largest ice shelves for some time. In the last five months alone, the fracture has grown an extra 22 kilometers, and it's only a matter of time before it breaks free.

Giant 30-mile long ice shelf will soon break away from Antarctica

A massive 30-mile long ice shelf, now barely hanging on to the coastline of Antarctica, is soon to break away. Scientists say the future iceberg, twice the size of Manhattan, is not necessarily breaking off due to global warming.

Video: New NASA animation shows Antarctica without ice

Sheets of ice one mile thick cover most of Antarctica, obscuring many of its geographical features. Now a new animation by NASA offers the most detailed and accurate picture yet of what the landmass would look like if all that ice were to melt.

Scientists discover Antarctic ice shelf at risk of collapse

Scientists have discovered a sub-glacial basin in the Antarctica region which they believe is due for imminent collapse. The previously unknown area is the size of New Jersey (7,770 sq miles).

Wilkins Ice Shelf Hangs By Last Thread

The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island.

The torpedo-shaped robots (technically underwater drones) are called Seagliders, and they were developed with support from the National Science Foundation. The drones will venture into ocean cavities and take readings under the ice.

A photo from the window of NASA's DC-8 shows the rift across the Pine Island Glacier ice shelf running off toward the horizon. The plane flew across the crevasse on Oct. 26, 2011 as part of NASA's Operation IceBridge, and also flew directly over the rift for about 18 miles, taking detailed measurements of its depth, width and shape. The ice shelf hasn't calved a major iceberg since 2001, and IceBridge took advantage of the opportunity afforded by spotting the crack to fly over it and measure its

The satellite images not only capture the crack's length, but also the "texture" of the ice shelf with smooth ice depicted as blue and rougher areas — like the rift and open water — as orange. Credit: Jesse Allen/NASA Earth Observatory
