   Description: 
      Abstract:
         From 1893 to 1956, the Danish Meteorological Institute (DMI) created charts of 
         observed and inferred sea ice extent for each summer month. These charts are 
         based on compiled observations of ice conditions reported by a variable 
         network of national organizations, shore-based observers, scientific 
         expeditions, and ships as detailed in each report; in cases where no 
         observations were available, the lead mapmakers extrapolated further ice cover 
         using their knowledge of ice movement. Except for where direct observations 
         are indicated, caution is advised in using the charts’ ice edge because there 
         is no way to quantify the assumptions used in extrapolating ice edge or the 
         error involved in this method. See the note on reliability for further 
         discussion of potential error. The charts were scanned at the Icelandic 
         Meteorological Office (IMO) and are being made available here as a service and 
         in cooperation with DMI and other contributors. In all, there are 266 image 
         files containing 291 images.
