Interesting site - I'll add that to my favourites. The
decline is quite marked but there seems little difference in the
maxima (Feb/Mar). This would seem to indicate that the ice is
shallower.

I returned to this site again today and the melting in less than two weeks
is amazing. You are quite right in suggesting the ice is thinner. The
colours clearly indicate that. Anyone doubting the existence of GW will
surely be convinced by this.

It certainly fits in with the mean monthly sea-level pressure pattern
which shows high pressure in the Greenland/Iceland region, and
a positive anomaly centre of +5mbar over eastern Greenland.
(I'll provide a link in my synoptic review when I've uploaded the
relevant pages).
