Important Notices
The surface current forecasts of the St. Lawrence Estuary are extracted from a three-dimensional numerical model that synthesizes the oceanic circulation under the influence of the tides and of fresh water runoff from the St. Lawrence River, but without wind forcing. The model results were validated against a statistically significant series of drifting buoy tracks in calm weather conditions. The tides are responsible for a high percentage of the current energy in this region, but the forecasts must be used with caution in intense or extreme wind conditions.

The surface currents forecasts for the Gulf of St. Lawrence are extracted from a three-dimensional numerical model computing the oceanic circulation under the influence of tides, the St. Lawrence River fresh water runoff, and the atmospheric forcing. The model has been validated under a series of scientific and operational research and development programs within the Department of Fisheries and Oceans Canada. The validation process was done against a number of oceanographic observations including currents, water level, water temperature and salinity.
