GlobCoast has contributed to better understand the coastal biogeochemical cycles, and their relationships with physical forcing occuring in coastal areas, and the evolution of productivity and fish resources.
The seasonal, inter-annual, and decadal evolution of the global coastal waters, in terms of biogeochemical composition as revealed from satellite ocean colour observations, were assessed and analysed for the very first time using new approaches developped during the project. Time series of biogechemical parameters were analysed conjointly with various physical forcing parameters as obtained from remote sensing, in situ measurements and modelling to better understand the origin of their temporal variability. This was performed over highly contrasted areas covering a great variety of environmental, biological and bio-optical conditions encountered in coastal areas like the English Channel and the North Sea, and the Amazon-influenced coast in French Guiana. Finally, the potential link between the variability of these environmental parameters and the variance in the recruitment and stocks of fishes was investigated.

HYGEOS was in charge of atmospheric correction of satellite data.
