the realization, under the surveillance control network (RCS), of 6 campaigns per year as part of the hydrological network of the Reunion coast. These campaigns include in-situ measurements of basic physico-chemical parameters: pH, conductivity, dissolved oxygen, water temperature using portable probes. They also include water and phytoplankton samples primarily for nutrient analysis, chlorophyll a/pheopigments and phytoplankton counts.
