Cache of historical Arctic sea ice maps discovered

Watts Up With That?

Arctic Sea ice data collected by DMI 1893-1961

Guest post by Frank Lansner

I came across a number of maps showing Arctic ice extend from 1893 to 1961 collected by DMI in “Nautisk Meteorologisk Aarbog”. Each year DMI have collected information on sea ice extend so that normally each of the months April, May, June, July and August ice extend was published.

There is much more to be said about these, but this is my summary for now.

Sadly, just for a few years we also have March or September available, and thus we normally can’t read the Arctic ice minimum (medio September) from these maps. The August trends will have the main focus in this writing.

First of all I would like to thank “Brunnur” in Iceland for making these maps available on the net beautifully…
