Maintained by the Michigan Sea Grant and Michigan State University's Remote Sensing and GIS Research and Outreach Service, this web site offers data on current surface temperatures of the five Great Lakes. Using interactive maps, users can specify size of temperature maps by the entire lake, a region, or a port. Students can find educational materials about general temperature concepts such as thermal fronts. Through these maps, users can learn about isotherms, temperature, satellite imagery, latitude and longitude, and more.
