Arctic sea ice reaches lowest extent for 2009

The National Snow and Ice Data Center (NSIDC) is part of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado at Boulder. NSIDC scientists provide Arctic Sea Ice News & Analysis content, with partial support from NASA.

The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest extent recorded since satellites began measuring minimum sea ice extent in 1979. While this year's minimum extent was greater than the past two years, it is still below the long-term average, and well outside the range of natural variability.

NSIDC will issue a formal press release at the beginning of October with full analysis of the possible causes behind this year's ice conditions, particularly interesting aspects of the melt season, the set up going into the winter growth season ahead, and graphics comparing this year to the long-term record.
