AbstractHudson Strait is a major waterway that links Hudson Bay and Foxe Basin with the Labrador Sea and North Atlantic Ocean. Ungava Bay forms a large embayment adjoining the eastern part of the strait. In the past, Hudson Strait has been a major discharge route for glacial ice from the northeast sector of the Laurentide Ice Sheet to the North Atlantic Ocean. Extensive surveys with high-resolution seismic equipment and sampling of seabed sediments, mainly by piston coring techniques, have delineated the principal surficial sediment units, their distribution and depositional environments, and provide information regarding glacial ice margins, glacial-marine interactions, and late glacial-deglacial history, including relationships with events recognized in adjoining terrestrial and marine areas. This paper reviews the bathymetric and oceanographic settings, seasonal ice conditions, methods of investigation, and the results of previous marine studies. It also acknowledges the significant contributions to this study by many other workers.
