Those covering that era (August? 1959 to sometime in 1982?) were
produced by the Met Office and should be available at their
Library/Archive but the paper copies may have gone missing. I've asked
for copies (they used to cost 3/6d!) but have been told that I can only
see them by visiting Exeter. If I'd known how important they'd become
I would've kept copies during the time I was producing them.

The Met Office started production of Arctic Ice charts after the
Danish Met Institute end theirs. Their entire production (1893-1956) is
online he http://brunnur.vedur.is/pub/trausti/. The charts are at
the bottom of the page, either as jpg or pdf.

In the absence of easily-available charts for 1963, I used the following
graph to compare 2007 with 1963:

I used 2007 because this year has just overtaken that year to be in
second place behind 2012.

Thanks Graham,

I had forgotten about http://arctic.atmos.uiuc.edu/cryosph....1900-2010.png

It would be nice if someone could get your maps from the Met Office and put them on the web, but won't there be a problem with copyright? But I am not volunteering. I've already got too many unfinished jobs :-(

Cheers, Alastair.
