Daily Arctic Sea Ice Images back Online

The daily Arctic sea ice images from the National Snow and Ice Data Center (NSIDC) were brought back online on Tuesday. The NSIDC completed the transition from the Defense Meteorological Satellite Program (DMSP) F13 satellite, to the DMSP F17 satellite, which will allow the NSIDC to continue their long-term record of sea ice extent.

Looking at the latest sea ice extent, it appears that there was a significant drop off during the month of May. At the start of the month, the sea ice extent was very close to the 1979-2000 average, but by the end of the month it was closer to the record minimum year of 2007. Time will tell where it ends up at the end of the melt season in September.

Here is that same graph going back one year to June 3, 2008.

Let's go back one year and see what the sea ice concentration looked like on June 2, 2008

It appears that there are many more areas of lower sea ice concentration currently compared to last year, especially on the Canadian side of the Arctic.
