Description:
Our data set includes nine probability maps of sea ice extent, available in .jpeg and shapfiles. They were created from historical maps of sea ice extent off Iceland dating back to 1877 compiled by Koch (1945) that we digitized. We use these maps in combination with sea ice charts from the Danish Meteorological Institute (DMI) and Koch's sea ice index from 1820 to 1939 to provide spatial maps of estimated sea ice extent between Iceland and Greenland back to 1821.
The probability maps should be used in combination with the table: Summary of Koch's Index Years, in order to know which years fall under which category.
