Sea Ice Today
Analyses
As some of our readers have already noticed, there was a significant problem with the daily sea ice data images on February 16.
As is typical during mid-winter, sea ice extent increased overall in January; maximum monthly extent is expected in March. However, January ice extent remained well below normal compared to the long-term record.
In this month’s entry, we offer a review of the 2008 year in Arctic sea ice.
As is normal for this time of year, ice extent increased rapidly through most of October. However, this year, the increase was particularly fast, which contributed to above-average air temperatures near the surface.
The Arctic sea ice cover appears to have reached its minimum extent for the year, the second-lowest extent recorded since the dawn of the satellite era. While above the record minimum set on September 16, 2007, this year further r
The pace of sea ice loss sharply quickened in the past ten days, triggered by a series of strong storms that broke up thin ice in the Beaufort and Chukchi Seas.
Arctic sea ice extent has declined through the month of May as summer approaches. Daily ice extents in May continued to be below the long-term average and approached the low levels seen at this time last year.
Spring has arrived in the Arctic. After peaking at 15.21 million square kilometers (5.87 million square miles) in the second week of March, Arctic sea ice extent has declined through the month of April.
Arctic sea ice reached its yearly maximum extent during the second week of March, 2008. Maximum extent was slightly greater compared to recent years, but was still well below average.
