How is isostatic rebound affecting the Hudsons Bay lowlands?
Post-glacial rebound (sometimes called continental rebound, isostatic rebound, isostatic adjustment or post-ice-age isostatic recovery) is the rise of land masses that were depressed by the huge weight of ice sheets during the last glacial period, through a process known as isostatic depression. It affects northern Europe, especially Scotland, Fennoscandia and northern Denmark, Siberia, Canada, and the Great Lakes of Canada and the United States. How fast and how much (i.e. the amplitude) postglacial rebound proceeds is determined by two factors: (i) the viscosity or rheology (flow law) in the mantle, and (ii) the ice loading and unloading histories on the surface of Earth.
