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 :-(


I would've done it but I have a horrible feeling that they've got rid
of the A4/foolscap published charts and merely retained the working
charts. I recall that it was official policy forty-five years ago that
only original working charts had to be kept although I'm fairly sure
the published monthly ice maps were there a few years ago, they're just
not listed in that format now. In any case, I'm not traipsing down to
Exeter on a wild goose chase.
