The Dehn Collection of Arctic Sea Ice Charts, 1953-1986, Version 1

The National Snow and Ice Data Center holds a collection of charts depicting ice conditions in the seas off Alaska and western Canadian coasts. Ice edge position and some ice concentration and other information are included, though the notations on the charts are often sparse and discontinuous in space and time, especially for older charts in the series. These charts, more that 6,800 in number, were donated to NSIDC by the estate of William S. Dehn. NSIDC has partnered with the NOAA Climate Database Modernization Program (CDMP) and the National Geophysical Data Center (NGDC) to scan the charts and to make them available through a searchable interface.
