Projet EMACOP : caractérisation des vagues et du potentiel houlomoteur des sites d’Esquibien et de Saint-Guénolé par simulation numérique

The French research EMACOP project aims at characterising wave power nearby onshore structures. This paper presents the application of the non-hydrostatic wave-flow model SWASH to wave propagation and transformation on two hot spots in Brittany. The numerical simulations were performed for dominant wave conditions and three tide levels. The results of wave simulations allow us to characterise wave energy resources and define Wave Energy Converters (WEC)'s promising positions on both sites.

Evaluation du stock de coquilles Saint-Jacques de la Baie de Seine et du Proche Extérieur. COMOR 32 (8-23 juillet 2002)

Scientific scallop surveys called COMOR are carried out in the bay of Seine since 1976. Results are used by fishermen’ associations and by fishing administration to lead management measures. In this report, the scientific results of the survey COMOR 32 realised in July 2002 are described. Abundance and growth indices for scallop, by age and area, are presented. During these surveys, data about most abundant benthic species are also collected since 1998. A first assessment with five years data is made here. A global descriptive analysis is undertaken about all the species present on scallops grounds. A special zoom is applied on both species whitch could be exploited (whelk Buccinum undatum and queen scallop Aequipecten opercularis) and three competitive species (starfish Asterias rubens, American slipper-limpet Crepidula fornicata and brittle star Ophiothrix fragilis)
