The colour of seawater, seen from space, is used to estimate the chlorophyll content in the water. This pigment is an index of the biomass of microscopic algae. Compared to the Atlantic Ocean, the waters of the Estuary and the Gulf of St. Lawrence are rather isolated and are strongly mixed with fresh water from many rivers.
The method for retrieving chlorophyll must be adapted to these specificities. This dataset presents the result of a method developed to find the concentration of chlorophyll-a derived by various satellites (5) in the estuary and the Gulf of St. Lawrence. The two satellites (AQUA and VIIRS) are still active and collect daily data.
This project is part of the Coastal Environmental Baseline Program Initiative under the Oceans Protection Plan of Fisheries and Oceans Canada.
USAGE NOTE : Some of the CSV format files below are large. They have therefore been compressed to facilitate downloading. Once uncompressed, it is advised to open these files using programs such as Notepad ++, Sublime Text, MATLAB, RStudio, etc. Since Microsoft Excel is not suitable for the size of daily files (approximately 1,500,000 lines per file), it partially truncates the data.
