The flow of water along the shelf from Newfoundland to the Mid-Atlantic Bight is largely buoyancy-driven from local and distant freshwater sources including Hudson Bay runoff and glacial or sea-ice melt from the Labrador Sea. Climatic changes in the net precipitation minus evaporation patterns between 40-65o N could alter both local runoff and the strength and relative freshness of the along-shelf flow entering the Gulf of Maine and Georges Bank. Changes in the magnitude of the subtropical Gulf Stream and subpolar Labrador Current transport due to differences in wind forcing, air temperature, and salinity could significantly impact the position and dynamics of ocean fronts, rings, and other features in the Georges Bank area. Such changes may also affect the timing, intensity and location of stratification on the region's submarine banks. Other important processes, including water formation in the Labrador Sea (Lazier, 1981) and sea ice development (Hill and Jones, 1990), may be linked to climate change and other long-term fluctuations.
