Ice Loss in Antarctica

Rebecca Maxwell

In the last six years, a 750 kilometer (466 mile) strip of Antarctica has been shedding ice into the ocean at a rate of about 60 cubic km each year according to data collected from Cryosat-2.

On Sept. 19, 2014, the five-day average of Antarctic sea ice extent exceeded 20 million square kilometers for the first time since 1979, according to the National Snow and Ice Data Center. The red line shows the average maximum extent from 1979-2014. Image Credit: NASA's Scientific Visualization Studio/Cindy Starr

New Record Extent of Sea Ice in Antarctica

Rebecca Maxwell

The polar regions of the Earth, the Arctic Ocean and Antarctica, are of particular concern to scientists and researchers. In ...

Using 200 million measurements collected by ESA’s CryoSat mission between January 2011 and January 2014, researchers from the Alfred Wegener Institute in Germany have discovered that the Antarctic ice sheet is shrinking in volume by 125 cubic kilometres a year. The study, which was published in a paper published on 20 August 2014 in the European Geosciences Union’s Cryosphere journal, also showed that Greenland is losing about 375 cubic kilometres a year
