| This is the 30th annual surveillance report concerning the central nuclear power plant of Gravelines. This very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveillance studies concern monitoring of fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), benthic system (intertidal and subtidal) and pelagic system (hydrology, microbiology, phytoplancton, zooplancton). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the... |

| Along the coast of France in the English Channel, muddy fine-sand communities are restricted to bays and estuaries, but in the southern North Sea they stretch out to larger areas (mesoscale continuum). We studied three regions containing these communities, each subject to different hydrological conditions and contrasting trophic structures of the water column. The Bay of Morlaix was strongly affected by the "Amoco Cadiz" oil spill of 1978 and recovered slowly. The Bay of Seine is influenced by high levels of nutrient input from the River Seine. A retention structure exists in the eastern part ensuring recruitment stability. The Gravelines area in the southern North Sea was invaded by the American jackknife clam (Ensis directus), which became a key species... |
