Maximum Extent of Antarctic sea ice in 2013 (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption Sea ice surrounding Antarctica has been expanding since the beginning of the satellite record in 1979, reaching a new record extent of over 7.72 million square miles on Sept. 19, 2014. Still, this upward trend pales in comparison to the rapid loss of sea ice in the Arctic. These maps show the maximum extent of Antarctic sea ice in 2013 as observed by satellite. October is typically the global maximum for sea ice, largely because of the vast extent of Antarctic ice at that time.
