Comparison of Elevations of Archaeological Sites and Calculated Sea Levels in Arctic Canada

Based on a study of postglacial uplift in the Canadian Arctic, it has been proposed that relative emergence can be estimated if the age and elevation of late-glacial marine limits are known. This suggestion is used to construct 5 maps showing the amounts of relative sea level emergence since 4000, 3...
