There are still a few weeks of melting before the autumn freeze starts.


Any idea why the measurement of the area of ice is so different as that
at NSIDC - 5.26? They both agree it's a record but can't agree on the
value. NSIDC tends to overestimate the amount of ice - it still shows ice
in Hudson Bay and Siberian rivers, for example - but I don't see this as
being enough to account for the difference.

I can only think they are measuring different percentages of ice cover.
Do you have a ready to hand link to what you are seeing at NSIDC, as I
find that site particularly hard to navigate?


Sorry Mike. I'd originally included a link to the relevant page but it got
lost in some re-editing. See
