Minimum Sea Ice Extent (WMS)

Each year, the ice covering the Arctic Ocean grows during the northern hemisphere winter and shrinks with the northern hemisphere summer. The ice extent is usually greatest during the month of March and is the least during the month of September. This image shows the average minimum extent of sea ice over the northern hemisphere during the month of September over 24 seasons, from 1979 - 2002. The red line shows the area where the average sea ice concentration is 15%.
