Hi Graham, Where can I see charts of the sea-ice before the satellite era, especially 1962,3 & 4? 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: http://arctic.atmos.uiuc.edu/cryosph....1900-2010.png I used 2007 because this year has just overtaken that year to be in second place behind 2012. -- Graham P Davis, Bracknell, Berks.

[Retd meteorologist/programmer] http://www.scarlet-jade.com/ I wear the cheese. It does not wear me. Posted with Claws: http://www.claws-mail.org/ I found that seasonal extent chart very interesting. I have seen it before but not studied it in as much detail as now. Looking at the summer changes in particular, it would appear that the decline in summer ice extent began as far back as the early 1950's with the more significant decline from around 1970 onward. Experts may correct me but to me, the summer decline is the most important as that removes a bulk of the older, thicker multiyear ice. If 2012 was on there, then the last decades decline would look even worse. How was extent measured in detail before the current satellite era, i.e. 1979 onward according to sites such as NSIDC and the UIUC Cryosphere site? -- Pete Malvern Wells, S Worcs, 111m asl.

Posted with Claws: http://www.claws-mail.org/ 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. |
