September is the month when in the Arctic the sea ice area reaches its minimum. The map and time series show a comparison of current ice conditions to previous years.

Sea Ice Minimum and Maximum in the Arctic

Credits: Sea ice concentration calculated at the University of Bremen from 89 GHz data of the AMSR2 sensor on the GCOM-W1 satellite; background: "Blue Marbleā€ MODIS data from the NASA Earth Observatory; 1981-2010 sea ice contour from NSIDC: National Snow and Ice Data Center.

The extent of sea ice in the Arctic shows a strong seasonal cycle: in March the sea ice area reaches its largest and in September its smalles extent. During recent years the sea ice extent has reduced significantly compared to the long-term median of the 20 years 1981 to 2010.
