The first aim of the GLOBCOAST project is to assess and analyse the seasonal, inter-year and decennial change in global coastal waters in terms of biogeochemical composition using satellite observations of the colour of the ocean.
The temporal series of these biogeochemical parameters will be analysed along with various physical forcing parameters obtained via satellite observations, in situ measurements and modelling. This will help to gain a better understanding of the origin of temporal variations in biogeochemical parameters of global coastal waters.
In addition to its fundamental role in marine biogeochemical cycles, phytoplankton, which is at the first level of the marine food chain, transmit energy towards the upper trophic levels and then directly and indirectly influences the biodiversity of other organisms such as zooplankton, fish and marine mammals. This project will lead to a better understanding of the origin of variations in phytoplankton in the coastal system.
The second aim of this project is to analyse the potential link between the variation in the environmental parameters, measured in the first part of the project, and the variations in the recruitment and stocks of organisms in the upper trophic levels (shrimp and fish). Economic impact indicators for the environmental disturbances detected will be proposed. This will be carried out over three very different areas encompassing a wide variety of environmental conditions encountered in the coastal areas: the Channel and the North Sea, the main coastal upwelling systems.
This project was labelised by the AQUIMER Pole of Competitiveness on the 13th July, 2010.
