This data set contains daily visual ice observations taken yearly from 1 November to 30 April at NOAA/National Ocean Service water level gauge sites in the Great Lakes Basin from 1956 to the 1997. Not all gauge sites have reported each season; a list of sites with coordinates and reporting years is included with the data set. The longest records tend to be at river stations such as St. Clair, St. Marys, Detroit, and St. Lawrence. Daily observations are coded (open water, solid ice, honeycombed ice, slush ice, windrowed ice, drifting ice, or ice gorge), as well as first and last reported ice for each season.VIEW RELATED INFORMATIONhttps://dx.doi.org/10.7265/N5PN93HTDocumentationGET DATAhttps://noaadata.apps.nsidc.org/NOAA/G00945/HTTPSPROJECT HOME PAGEhttp://www.glerl.noaa.gov/data/ice/atlas/NOAA Great Lakes Ice AtlasUSA/NOAACEOS IDN DIFVERSION 9.91995-01-012026-09-15NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCLevel of ServiceBasicNSIDCFull Dataset CitationNational Snow and Ice Data Center.
