      <abstract>
        Ice type codes, recorded daily from 1 November - 30 April by cooperative observers at up to 39 NOAA/National Ocean Service water level gauge sites on the Great Lakes, 1955/56 to 1996/97, are archived. 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 (St. Clair, St. Marys, Detroit, St. Lawrence.)  Daily observations are coded (open water, solid ice, honeycombed ice, slush ice, windrowed ice, drifting ice, ice gorge), as well as first and last reported ice for each season. This time series is a unique data set.
