Excerpt
Abstract: An interactive, menu-driven computer tutorial was developed to provide an overview of the Great Lakes ice cycle. The tutorial includes an animation to aid in visualizing the seasonal progression and the spatial patterns of ice cover for the base period 1960-1979. The computer algorithm was developed from data contained in the NOAA Great Lakes Ice Arlar. This material is presented as a government technical memorandum to make the tutorial available to the public at large for educational purposes. A computer diskette needed to load and run the tutorial (on a Macintosh Plus with at least 2 megabytes of memory) is included as an appendix. Background information on the ice cover data and methods used to create the tutorial is followed by a description of the spatial and seasonal ice cover distribution patterns as related to lake bathymetry...
