Dehn, W. S. 1979. Inadequacies in Archive Sea Ice Data. Glaciological Data Report : Workshop on Snow Cover and Sea Ice Data. GD-5 p 101-106. World Data Center A for Glaciology (Snow and Ice). Boulder, CO.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.VIEW RELATED INFORMATIONhttps://dx.doi.org/10.7265/N5F769GDDocumentationPROJECT HOME PAGEhttps://nsidc.org/data/dehn_ice_charts/dehn_ice_charts.htmlSearch DatabasePROJECT HOME PAGEhttps://nsidc.org/data/ewg/Environmental Working Group Arctic AtlasesPROJECT HOME PAGEhttps://nsidc.org/noaa/gdsidb/Global Digital Sea Ice Data Bank (GDSIDB)VIEW RELATED INFORMATIONhttps://nsidc.org/data/g02140Morphometric Characteristics of Ice and Snow in the Arctic Basin: Aircraft Landing Observations from the Former Soviet Union, 1928-1989VIEW RELATED INFORMATIONhttps://nsidc.org/data/g02203 Arctic Sea Ice Charts from Danish Meteorological Institute, 1893 - 1956USA/NOAACEOS IDN DIFVERSION 9.92005-07-012025-10-07NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCLevel of ServiceStandardNSIDCFull Dataset Citation(2005). <i>The Dehn Collection of Arctic Sea Ice Charts, 1953-1986</i>.
