Ice, Wind & Fury

Greenlanders are well away of piteraqs, the hazardous torrents of cold air that sweep down off the ice cap. But scientists are just beginning to unravel how and when piteraqs form.

New Study Projects That Melting of Antarctic Ice Shelves Will Intensify

New Study Projects That Melting of Antarctic Ice Shelves Will Intensify

New research published today projects a doubling of surface melting of Antarctic ice shelves by 2050 and by 2100 may surpass intensities associated with ice shelf collapse, if greenhouse gas emissions from fossil fuel consumption continues at the present rate.

Ice shelves are the floating extensions of the continent’s massive land-based ice sheets. While the melting or breakup of floating ice shelves does not directly raise sea level, ice shelves do have a “door stop” effect: They slow the flow of ice from glaciers and ice sheets into the ocean, where it melts and raises sea levels.

A Mooring in Iceberg Alley

WHOI scientists knowingly put a mooring in a fjord filled with icebergs near the terminus of a Greeland glacier. But it was their only way to learn if changing ocean conditions might be affecting how fast the glacier flowed into the ocean.
