| This is the 31th annual surveillance report concerning the nuclear power plant of Gravelines. Its 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, phytoplankton, zooplankton). 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 area by... |

| Populations of Abra alba (Wood) (Mollusca : Bivalvia) were studied over a fifteen-years period at three sites: the southern part of the North Sea (Gravelines area), the Bay of Seine, and the Bay of Morlaix in the western English Channel. These surveys provide an example of long-term changes in a species considered as ''opportunistic'' and as a ''biological indicator'' of disturbance. A summed cumulated function was used to compare the changes of the Abra alba populations and of mean air temperature in each area. The graph of this function shows the timing and duration of changes. Four or five main periods were identified at each site, with a succession of periods of abundance, stability, and decrease. The abundance periods were separated by ten years in... |

| This is the 24th annual surveillance report concerning the central nuclear power plant of Gravelines. This very high power level (5400 MW) 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, phytoplankton, zooplankton).

| La stratégie d'étude modifiée en 1989 a pour but de cerner les impacts, par comparaison entre stations et choix d'espèces cibles. La puissance de fonctionnement de la centrale varie au cours de l'année de 4.5 à 6 tranches de 900 MW, le débit de refroidissement varie de 180 à 240 m3/sec. L' échauffement moyen du canal de rej et est de 8.9 0 C. L'eau recyclée es t estimée à 5.4 %. L'impact de transit se traduit par une multiplication intense des Vibrions, un déficit de biomasse chlorophyllienne (60 %), biomasse zooplanctonique (50 %), déficit dans l'abondance des oeufs (30 %) et larves (100 %) de soles. L'impact sur le milieu récepteur est visible dans le compartiment bactérien et sur les espèces benthiques. Le déficit en biomasse benthique subtidale du... |

| L'année 1994-1995 se distingue des périodes précédentes par un hiver peu rigoureux et, surtout, un été très chaud. La quantité moyenne d'électricité produite par la centrale pour la période est de 4 250 MW, soit l'équivalent de 4,7 tranches, pour un débit moyen calculé de 221 m3/s, soit l'équivalent du débit de pompage de 5,5 tranches. Sur cette base de calcul, l'augmentation moyenne de la température de l'eau au rejet est de 9,15°C. Cette valeur est du même ordre que celles des périodes précédentes. Les dosages des haloformes et, en particulier, du plus abondant d'entre eux, le bromoforme, montrent que la chloration a été en service pendant 9 des 12 mois de la période d'étude. |

| The ICES Study Group on the North Sea Benthos Project 2000 undertook to integrate recent (1999–2002) macrobenthic infaunal and environmental data from various national sources. The main aim was to compare the outcome with that of the ICES North Sea Benthos Survey conducted in 1986, to identify any significant changes and their likely causes. In the process, the exercise yielded valuable lessons for the conduct of international collaborative programmes, as well as insights into the utility of a range of interpretational tools. These are timely in view of increasing requirements for periodic sea-wide assessments of quality status to meet international obligations, such as those under OSPAR, ICES, HELCOM, and EU auspices for European waters.

| This is the 23th annual surveillance report concerning the Gravelines nuclear power plant. Gravelines, located between Calais and Dunkerque and very high power station (5400 MW) with sixth plants. liegining of electricity production in 1980 reached maximum production in 1986. Surveillance studies concern fisheries, intertidal and subtidal zoobenthos hydrology, microbiology, phytoplankton and zoplankton. Studies concern seasonal variations in natural environment and impact study at outfall of plant. |

| Le présent rapport de travail présente les résultats obtenus pour la période novembre 1983 - octobre 1984 devant la centrale de Gravelines. La surveillance écologique du site consiste à observer le pélagos et le benthos, en liaison avec les variations naturelles et celles dues au fonctionnement de la centrale du milieu physique et chimique, et à déceler d'éventuels changements dans la qualité et la biomasse des écosystèmes. Les résultats concernent les domaines d'études suivants - météorologie, - hydrologie, - microbiologie, - phytoplancton, - zooplancton, - benthos intertidal et subtidal. |
