   There are some known limitations in the input data collections referenced in 
   Divine and Dick (2006). March through August months were selected since these 
   months contain a high data density. Therefore, the annual cycle of sea ice 
   advance and retreat is not captured. See documentation for limitations by by 
   data collection.

Group: Summary

   This product contains ice edge coordinates for the Nordic Seas from 1750 
   through 2002 for months March through August. Ice edge in this product is 
   defined as the outer boundary of ice having at least 30% ice concentration. 
   Data are derived from publicly available sea ice products and use 
   observational data from ship logbooks, diaries and other sources in addition 
   to more recent satellite data products from the Scanning Multichannel 
   Microwave Radiometer (SMMR) and the Special Sensor Microwave Imager (SSM/I). 
   The data are distributed via FTP in ASCII, JPEG, and shapefile format.
