Chlorophyll-a and Salinity Concentrations Derived from Satellite Images for the Estuary and Gulf of St. Lawrence (1998-2023)

This dataset presents the result of a model developed to retrieve chlorophyll-a (chla) and salinity concentrations from various satellites in the St. Lawrence Estuary and Gulf. This version replaces the previous ones, with estimates derived from a retuning of the model based on additional in situ and satellite-derived data. The input data is now exclusively from the European Space Agency's Ocean Color Climate Change Initiative (CCI) program. The ocean color, seen from space, makes it possible to estimate the chlorophyll content in water. This pigment is an index of the biomass of microscopic algae. Compared to the Atlantic Ocean, the waters of the Estuary and Gulf of St. Lawrence are rather isolated and are highly mixed with fresh water from numerous rivers. This dataset is produced as part of the Coastal Environmental Baseline Program under Fisheries and Oceans Canada's Oceans Protection Plan.
