"On September 20 of this year, sea ice surrounding Antarctica covered 7.78 million sq miles (20.14 million sq km), according to NASA. That’s more than twice as big as the continental United States (3.11 million sq miles).
Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s.
Antarctic sea ice extent exceeded 7.72 million square miles (20 million square kilometers), according to the National Snow and Ice Data Center.
The ice extent stayed above this benchmark extent for several days.
The average maximum extent between 1981 and 2010 was 7.23 million square miles (18.72 million square kilometers)..."
