Objective	In the framework of the National coastal oceanography programme (PNOC), the Bay of Seine was chosen to study a zone enriched in nitrogen and phosphorus by a large river. Therefore, the studies conducted on this site by the DEL/CMCN laboratory fall under the PNOC's "Eutrophication" theme. The 1992 cruises (4 in all - SEDISEINE and PHYTOSEINE) focused on the distribution of nitrogen, phosphorous and phytoplankton in the water and sediment. The two PHYTOSEINE cruises are mostly devoted to studying phytoplankton.

Summary of measurements

-Hydrological sampling (at surface and bottom on all cruises).
-Sediment samples taken at 12 stations (Shipeck grab).
-Sampling at 5 stations ranked according to salinity, one of them in fresh water (around Tancarville); The samples are taken while going up the estuary, i.e. against the current.
