Abstract:

Bands of mobile ice are common features in the Great Lakes nearshore zone during the winter months. Samples were collected during December, 1989 to determine the sediment content in the mobile ice. Analysis of these samples and estimates of drift rates and ice volumes show that approximately 110 m³ day^-1 of sediment was being transported alongshore by the ice. This is 13% of calculated ice-free wave-induced sediment transport.
