The final tally for the yearly sea-ice decline has been released by the NSIDC. Note the difference between the "area" value calculated by Bill Chapman for September 16, 2007 (2.92 million sq. km), and the "extent" number given by the NSIDC (average for the month of September was 4.28 million square kilometers or 1.65 million square miles). Both are very much smaller than the previous records for each variable.
http://nsidc.org/news/press/2007_seaiceminimum/20071001_pressrelease.html There's an article by Andy Revkin in today's NYT about the remarkable loss of sea-ice this year. Here's a link: http://www.nytimes.com/2007/10/02/science/earth/02arct.html?hp I like the photograph which accompanies the article, as it shows the impact of the mirror like surface of the ocean at high zenith angles, which has been something I've tried to point out for years. One can also see the melt ponds which form on the surface of the sea-ice. http://graphics8.nytimes.com/images/2007/10/02/science/02arct.xlarge1.jpg When the story was first linked thru the main NYT home page with a picture of the Arctic Ocean sea-ice cover near the minimum, but that graphic is no longer available there. It may be seen in the supplemental graphics, which are linked thru the "multimedia" box, which is a FLASH player file. There's also a story from the BBC about the large ice berg in the Arctic, which broke off of the Ayles Ice Shelf in 2005. The map of it's travels is interesting too: http://news.bbc.co.uk/1/hi/sci/tech/7022192.stm E.S. ---------------------------------------------------------------------------------------------- [EMAIL PROTECTED] wrote: > According to Cryosphere Today, as of 28th August, the sea ice area is > 2.99 million km2 which is an impressive 25% below the previous record > low (http://arctic.atmos.uiuc.edu/cryosphere/). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
