Ice Conditions Along the Illinois Waterway as Observed on Landsat Images, 1972-1985
Landsat images were used to map ice distributions along the navigable portions of the Illinois Waterway from the Mississippi River to Lake Michigan, and air temperature and discharge data were used to characterize the conditions under which the observed ice formed and changed. The presence or absenc...
