| Abstract |
During spring, a hydrological profile was carried out in the river and bay of Morlaix (Finistere, France), in particularly favourable climatic conditions. Low salinity gradients were obtained. The distribution of nutritive salts clearly showed 2 different zones. The 1st, estuarine, was characterized by an important production and a great consumption of the dissolved silica. The other, the Bay, open to the sea, showed a distribution of nutritive salts which indicated that the benthic macroscopic algae accounted for {approx} 80% of the total consumption. The rates of consumption observed suggest that the water must remain at least 2 days in the estuarine zone and 3 days in the Baie de Morlaix. |
