Antarctic sea ice shrinks for second-straight year

Sea ice cover in Antarctica has dropped to its second-lowest on record, Australian authorities said Friday, adding that it was not yet clear what was driving the reduction after several years of record-highs.

End-of-summer Arctic sea ice extent is eighth lowest on record

Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have reported. Analysis of satellite ...

NASA scientists seek to improve sea ice predictions

Sea ice in the Arctic Ocean is in a downward spiral, with summer minimum extents about 40 percent smaller than in the 1980s. But predicting how the sea ice is going to behave in a particular year is tricky: There are still ...

New model helps predict regional and seasonal sea ice extent

Scientists have developed a new method to forecast the extent of sea ice in some regions of the Arctic up to 11 months in advance. The method, which incorporates information about ocean temperatures and focuses on regions ...

NASA snaps picture of new crack in Greenland ice shelf

(Phys.org)—A team of researchers working with NASA's Operation IceBridge has snapped a picture of a crack in the middle part of Petermann Glacier—it resides on Greenland's northern coast. The photo and other accompanying ...

NASA's aerial survey of polar ice expands its Arctic reach

For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable ...
