| 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... |

| Recent measurements (1986-1988) of the distribution of the concentration of different nutrients (nitrogen, phosphorus and silicate) in the Dover Strait have been used, combined with older results, to calculate the total flux (dissolved and particulate) of nutrients into the North Sea. Special efforts are made to take into account in the fluxes the tidal, geographical and temporal variations in the concentrations of the different nutrients. No vertical gradients in the concentration of the different nutrients were found. Increased nutrient concentration was found in the coastal zones of England and France, compared to the Atlantic water in the central part of the Dover Strait The variation within a single year and between different years in the data... |
