| La stratégie d’échantillonnage optimisée du Réseau Hydrologique Littoral Normand (RHLN) a été approuvée en 2007 par ses partenaires, avec le triple objectif (1) d’observer les niveaux d’eutrophisation et les phénomènes associés pour comprendre leur déclenchement et évolution ; (2) d’évaluer la qualité des eaux selon les indicateurs réglementaires (DCE, OSPAR), et expertiser ces évaluations selon les connaissances actuelles du milieu ; et (3) d’améliorer et publier les connaissances via des projets de recherche, et permettre la validation des modèles. Ce rapport réalise la synthèse des résultats obtenus en 2014, douzième année depuis le début du suivi en Normandie. Le climat de l’année 2014 a été globalement une année chaude, avec un record de la moyenne... |

| 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. |

| An hydrobiological monitoring survey has been carried out in the Bay of Marennes-Oléron since 1977. Five stations, distributed over the Bay, were sam pied twice a month. Spatial and temporal trends of the physical characteristics (i.e., seawater, temperature, salinity, dissolved oxygen and suspended matter), nutrients (azote, nitrite, nitrate, silicate) and organic variables (chlorophyll a and pheopigments) were assessed by using a statistical time-series analysis mode\. It was used to distinguish seasonal variability from long term trends. Pluviometric data as weil as the Charente River fluxes were similary analyzed by the model. The seasonal variability showed an homogeneous pattern over the five stations for all parameters, but the site-dependent... |

| This is the 33th 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. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). 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... |

| In the scope of the "Coastal ecology" thematics, the LCPC supervises a study which aims at understanding the causes and mechanisms of the summer mortality of C. Gigas. Different types of analysis conducted on the oyster (quality index, immunology, cell biology, etc.) enable the identification of a one month period preceding the acute mortality episode and during which the animals undergo a stress situation and become weaker. The energy balance (material balance) is close to zero for the most exposed stocks. Studies conducted on the environment included the search for pathogens and contaminants in the water column, the sediment and the animal, as well as the analysis of the hydrological features of the mass of water. The weakening period corresponds to an... |

| L'objet de l'étude est de décrire les liens principaux entre l'hydrologie de la Charente et les constats qualitatifs dans le bassin de Marennes, ainsi que l'estimation des flux continentaux, sur la base des données des stations de Fontenelles et de Boyard entre 1977 et 2006. Du fait de l'influence de la marée, il n'est pas possible de mesurer les débits de la Charente dans sa partie aval. Ils ont donc été reconstitués à partir des stations de Saint-Savinien, du pont de Beillant, de Carillon, du Moulin de Chatre, de la Lijardière, de Jarnac, de Vindelle et de Foulpougne, en fonction de la disponibilité et de la fiabilité des données. Les mesures à Fontenelles et Boyard ont été réalisées de façon à disposer d'une gamme variée de situations par rapport au... |
