Summary of measurements

-Sampling of water and zooplankton and measuring of primary production and nitrogen absorption by phytoplankton for 4 types of Seine plume water, referenced for their salinity.
-Sediment samples taken at 9 stations in the eastern Seine Bay.
-Measurement of O2, N and mineral P fluxes at the water-sediment interface using benthic chambers, at 4 stations in the eastern Bay of Seine.
