attribute NC_GLOBAL summary String 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 Visible and Infrared Imager/Radiometer Suite (VIIRS) are still active and collect daily data.
attribute NC_GLOBAL summary_fr String La couleur de l'eau des océans, vue de l'espace, est utilisée pour estimer la concentration de chlorophylle dans l'eau. Ce pigment est un indice de la biomasse algaire microscopique. En comparaison avec l'Océan Atlantique, les eaux de l'estuaire et du golfe du Saint-Laurent sont relativement isolées et fortement mélangées avec de l'eau douce provenant de nombreuses rivières.

La méthode pour déterminer la concentration en chlorophylle doit être adaptée à ces spécificités. Cette base de données présente les résultats d'une méthode développée pour trouver la concentration en chlorophylle-a dérivées à partir de différents satellites (5) dans l'estuaire et le golfe du Saint-Laurent. Les deux satellites AQUA et VIIRS (Visible and Infrared Imager/Radiometer Suite) sont toujours actifs et collectent des données journalières.
