| The Bay of Seine receives the French river with the highest nutrient concentrations, especially phosphorus. Dissolved (phosphate) and particulate phosphorus fluxes have been determined from fortnightly serial data collected by the Port Autonome de Rouen. These determinants exhibit behaviour opposite to that of the river flow: phosphate concentration decreases hyperbolically and particulate phosphorus increases linearily. An approach based on the rate of domestic effluent treatment agrees well (20%) with the measured phosphate flux. The determination of the main particulate phosphorus forms (adsorbed, apatite, non-apatite inorganic, organic) was undertaken over the whole estuarine salinity range. The speciation of particulate phosphorus exhibits a great... |

| The distribution of dissolved Al in the Channel along the English coast shows the existence of a strong gradient of this element extending over a distance of several hundred nautical miles. These profiles suggest that wind-driven export from the North Sea to the Channel is seasonally important. These findings confirm the predictions of the recent circulation models of Salomon and Breton (1991). A gross mass balance of dissolved Al in the Channel indicates that the input of the river Seine is insignificant and that the contribution of other minor fresh water sources cannot account for the observed values. The input of dissolved Al from the North Sea seems thus to be the most likely largest source of this element in the Channel. This could also be the case... |
