Group: Summary

   During the winters of 1965/66 through 1976/77, NOAA/Great Lakes Environmental 
   Research Laboratory (GLERL) collected weekly ice thickness and stratigraphy 
   data at up to 90 stations per year on the Great Lakes. Data include station 
   name, latitude, longitude and period of record as well as thickness of up to 
   six ice layers, total ice thickness, snow depth (on top of ice), snow 
   condition, ice condition, and ice type code. The data are useful for 
   site-specific shoreline engineering studies, winter navigation projects and 
   remote sensing ground truth. Constraints on the data include the relatively 
   short period of record (eleven seasons maximum for any one station). 
   Additionally, the time series may not reflect the full winter severity range. 
   Nearshore data may not be valid for nearby locations or representative of 
   offshore conditions, and ice type codes (the visual observation code) changed 
   in 1974/75. Both old and new code lists are available.
