We have received some constructive criticism from Anthony Watts to the effect that our resources section is sadly lacking in graphs, plots and maps of Arctic sea ice. The best such resource we are aware of on the web can be found at:

The Arctic Sea Ice Graphs web site.

In addition here are some additional graphs and maps focussing on Arctic sea ice thickness and volume that are difficult to update automatically. We shall endeavour to do so manually as and when time allows.
