Arctic Sea Ice Charts from the 1893 – 1956 Now Available

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 from Arctic expeditions and shore observers. The charts were scanned at the Icelandic Meteorological Office (IMO) and are being made available by NOAA@NSIDC as a service and in cooperation with DMI and other contributors. To access the data and learn more about it, see the Arctic Sea Ice Charts from Danish Meteorological Institute, 1893 – 1956Web page.
