this is the latest official map of arctic pack ice extent -as of November 2009.  Please note that in the east it is of further extent than the average from 1979 to 2000 - yet in 2007 it was in the east that it showed its largest decrease promoting international headlines. All the ice lost then is back  .. and yet this winter is only just started. It is from the US National Ice and Snow data centre in Boulder and is available on its website.
