This year the extent of summer sea ice in the Antarctic is the lowest on record. The Antarctic sea ice minimum marks the day – typically towards end of February – when sea ice reaches its smallest extent at the end of the summer melt season, before expanding again as the winter sets in.

This year the extent of summer sea ice in the Antarctic is the lowest on record. The Antarctic sea ice minimum marks the day – typically towards end of February – when sea ice reaches its smallest extent at the end of the summer melt season, before expanding again as the winter sets in.

This year, sea ice extent contracted to 883,015 sq miles (2.28m sq km) on 13 February, according to data from the US National Snow and Ice Data Center (NSIDC).

The extent is a fraction smaller than a previous low of 884,173 sq miles recorded on 27 February 1997 in satellite records dating back to 1979. Scientists, including those at British Antarctic Survey, are monitoring the data closely and trying to understand why this year is presenting a minimum.
