This chapter discusses the role of Hudson Bay in the glacial history of the Laurentide Ice Sheet. After a review of previous work on the problem, calculations on the thickness of the ice sheet, based on geophysical models, indicate that the ice
sheet was dynamic over Hudson Bay, with a major divide lying east of the eastern coast of the Bay. Lastly the models are tested with relative sea level curves and with free air gravity anomalies. (P. A. Pirazzoli).
Conceptual models of circulation and sedimentation in arctic fjords are presented to illustrate the current understanding of these environments. Circulation is a vigorous process in these fjords and is enhanced by the loss of the fresh water cap
