Surveillance écologique et halieutique du site électronucléaire de Paluel. Année 2007 - Rapport scientifique annuel ArchiMer
Lampert, Luis; Abernot, Chantal; Antajan, Elvire; Davoult, Dominique; Delpech, Jean-paul; Meirland, Antoine; Migne, Aline; Nogues, Loic.
Monitoring n°30 of the Paluel nuclear power plant takes into account studies conducted between March and September 2007. Impacts on hydrology, microbiology, phytoplankton, zooplankton, fisheries, intertidal phytobenthos and zoobenthos are reported. This power plant has been in operation for twenty four years.

Impact of the Phaeocystis globosa spring bloom on the intertidal benthic compartment in the eastern English Channel: A synthesis ArchiMer
Spilmont, Nicolas; Denis, Lucie; Artigas, Luis Felipe; Caloin, Frederic; Courcot, Lucie; Creach, Anne; Desroy, Nicolas; Gevaert, Francois; Hacquebart, Pascal; Hubas, Cedric; Janquin, Marie-andree; Lemoine, Yves; Luczak, Christophe; Migne, Aline; Rauch, Mathieu; Davoult, Dominique.
From 1999 to 2005, studies carried out in the frame of regional and national French programs aimed to determine whether the Phaeocystis globosa bloom affected the intertidal benthic communities of the French coast of the eastern English Channel in terms of composition and/or functioning. Study sites were chosen to cover most of the typical shore types encountered on this coast (a rocky shore, an exposed sandy beach and a small estuary). Both the presence of active Phaeocystis cells and their degradation product (foam) did have a significant impact on the studied shores. The primary production and growth rates of the kelp Saccharina latissima decreased during the bloom because of a shortage of fight and nutrient for the macroalgae. On sandy sediments, the...

Surveillance écologique et halieutique du site électronucléaire de Paluel. Année 2009. Rapport scientifique annuel final ArchiMer
Monbet, Philippe; Antajan, Elvire; Claquin, Pascal; Davoult, Dominique; Delpech, Jean-paul; Le Gac-abernot, Chantal; Meirland, Antoine; Migne, Aline; Rolet, Céline; Rostiaux, Emilie; Talleux, Jean-denis.
The monitoring report (n°32) of the nuclear power plant located in Paluel takes into account scientific studies carried out between March and September 2009. Environmental effects and potential impacts on the aquatic ecosystem are reported through different chapters : hydrology, microbiology, phytoplankton, zooplankton, fisheries, intertidal phytobenthos and zoobenthos. This power plant has been in operation for twenty six years.

Spatial and temporal variability of CO2 fluxes at the sediment-air interface in a tidal flat of a temperate lagoon (arcachon bay, France) ArchiMer
Migne, Aline; Davoult, Dominique; Spilmont, Nicolas; Ouisse, Vincent; Boucher, Guy.
This study aimed to explore the spatial and temporal variability of benthic metabolism in a temperate mesotidal lagoon. This was achieved by measuring fluxes of CO2 in static chambers during emersion, both under light and dark conditions. Three sample sites were selected according to their tidal level (upper or mid), their sediment type (sand or mud) and the presence/absence of the seagrass Zostera noltei. The three sites were investigated at three seasons (end of winter, spring and beginning of autumn). At each site and each season, three benthic chambers were used simultaneously in successive incubations over the emersion period. The sediment chlorophyll-a content varied seasonally in the upper sands (reaching 283 mg.m− 2 in spring) but not in the mid...

Benthic metabolism over the emersion - Immersion alternation in sands colonized by the invasive Manila clam Ruditapes philippinarum ArchiMer
Migne, Aline; Trigui, Rima Jihane; Davoult, Dominique; Desroy, Nicolas.
The effect of an invasive infaunal suspension-feeding bivalve, the Manila clam Ruditapes philippinarum, on benthic inorganic carbon and nutrient fluxes was examined through in situ incubations. Measurements were performed in spring and summer on a tidal sandflat of the Rance estuary (south part of the Western English Channel) colonized by the Manila clam after its deliberate introduction in the 1990's. Benthic inorganic carbon fluxes were measured using light and dark benthic chambers both at emersion and immersion. Benthic nutrient fluxes were measured using dark benthic chambers at immersion. Inorganic carbon (IC) and ammonium sediment release under darkness at immersion reached 5.60 mmol m−2 h−1 and 441 μmol m−2 h−1 respectively for a clam density of...
