Abstract
The potential impact of global warming on sea-level rise in the Hudson Bay area was examined. Land-based ice melt and thermal expansion of ocean waters were compared to isostatic rebound rates. Thermal expansion was estimated using a one-dimensional analysis and a three-dimensional world ocean general circulation model. It was found that the combined impact on sea-level rise of land-based ice melt and thermal expansion of the world ocean was the same order of magnitude as the sea-level fall rates due to isostatic rebound. Thus, there is the possibility of a cessation or reversal of sea-level fall in the Hudson Bay area in the next 100 yr.
