| Cd and V were analyzed in planktonic species (zooplankton and diatoms), in flocks and in total seston (suspended materials) collected at eleven stations for seven sampling periods in the eastern area of the bay of Seine. Cd concentrations measured in planktonic species of the bay of Seine are identical to those measured in other oceanic areas, but V concentrations are generally higher. In the conditions of sampling, the role of both planktonic species and flocks in the horizontal fluxes of Cd and V in the bay of Seine appears not to be important (Cd) or negligible (V) compared to non-living materials (tripton). Nevertheless, this study should be continued in periods of diatom blooms. Flocks which present high Cd and V concentration probably have an... |

| As part of the MAST I-FluxManche initiative, a monthly (September 1990 to November 1991) sampling programme has been carried out in the Dover Strait. Samples were taken (weather permitting) at two depths at each of six standard stations between Folkestone and Cap Gris-Nez. Data from all surveys, in conjunction with estimates of water movement derived from hydrodynamic numerical model, have been used to calculate fluxes of nutrients between the Channel and the North Sea. Results demonstrate that although nutrient concentrations are lower in the central channel-waters than in the coastal zone, the dissolved nutrient flux to the North Sea is mom important for stations of the central part of the Dover Strait as water. Current concern about possible increases... |
