Groundwater Flow Dynamics in Subarctic Beach Using Radioactive and Stable Isotopes, Gulf of St. Lawrence, QcThis dataset presents a study of groundwater dynamics along a subarctic coastal environment of the St. Lawrence Gulf. To this purpose, sampling was conducted along a sandy beach located at the base of coastal cliffs in Rivière St. Jean, Quebec, Canada. Water samples were collected to measure concentrations of stable water isotopes (δ2H and δ18O) and short-lived radioisotopic tracers (222Rn, 223Ra,

Chlorophyll-a Satellite Data for the Estuary and the Gulf of St. Lawrence: CCI, Monthly Mean | Données satellitaires de chlorophylle-a pour l'estuaire et le golfe du Saint-Laurent : CCI, moyennes mensuellesThe 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 specificiti
