Graham, not surprisingly, has a more specific and credible point, but
difficult to evaluate without doing the calculations. I guess what it
would be nice to know is the area of ice with a mean thickness 1m (or is
that too think to melt now - perhaps 0.5m then). Don't know whether the
PIOMAS model can estimate this kind of number - it would be interesting to
see an output of area at different estimated thickness categories.

There are measurments of thickness being made by the European Cryosat team
at UCL. But they seem to be rather reluctant to release their data. So far
all that I can find is 14 measurements shown at the end of this video.

But the data is over a year out of date and does not cover the most
interesting months May - Sep.

Cheers, Alastair.
