Etat de la pollution par les hydrocarbures dans l'Aber Benoit ArchiMer
Allen, G.; D'Ozouville, Laurent; L'Yavanc, Jacky.
The Aber Benoît, a small estuary on the North West coast of Brittany was polluted by oil from the Amoco Cadiz oil spill. Preliminary results from water and sediment samples taken in the estuary in May 1978, show that two months after the initial spill, high concentrations of hydrocarbures existed in the water and sediments of the estuary. The Aber Benoît shows a well developed salt wedge and upstream increasing suspended sediment concentrations. Oil was dispersed more or less evenly throughout the water column, in the entire length of the estuary. In the bottom sediments, oil had accumulated to depths of 30 cm. Sand bars appear to induce a trapping of oil in the estuary channel.

Pommepuy, M.; Manaud, F.; Monbet, Y.; Allen, G.; Salomon, Jean-claude; Gentien, P.; L''Yavang, J..
An oceanographic survey of the bay of Brest (France) was conducted in 1977, together with an hydrological study of the rivers entering the bay. Samples were collected from rivers. Analysis of dissolved nutrients (nitrate, phosphate, ammonium, reactive silicate) and tentative solute budjets (observed and calculated) for nitrogen and phosphorous in drainage basin were performed.
