"Mortimer chronicles three centuries of inquiry into Lake Michigan from the Native Americans, who called it Michigani (Great Waters), to the French explorers, whose first recorded observations date from the 1600s, to present-day scientists, who use satellite views of the Great Lakes from outer space." "Lake Michigan in Motion is a source of information for amateur naturalists, students, teachers, public officials, a wide variety of scientists and natural resource managers, residents of Lake Michigan's shores, and others who use the lake for their livelihood and recreation."--Jacket.

Three numerical models are formulated for long-wave motion in a 180 km long gulf (Green Bay, Wisconsin) that opens into Lake Michigan. These models are used to investigate the response of the Bay to wind forcing and excitation by disturbances entering from the main Lake basin. Model simulations of water movements in the Bay have been done for two periods of 4 and 8 days respectively during 1969. Observed fluctuations in water level during these periods have been compared with the corresponding variations predicted by the models. Agreements and disagreements are discussed. These illuminate properties of the Bay's motion and raise some further questions.
