| Oyster ponds behave as organic matter accumulators, unlike wetlands which export a large part of their natural productivity towards the ocean as well as inorganic nitrogen towards the atmosphere through denitrification. Thus, to prevent eutrophication temporary drying-out is necessary, the physical effects of which are weIl known but who se biogeochemical processes are still poorly documented. The aim of the present study was to perform a drying -out operation in an oyster pond, and to describe the modifications which occurred within the nitrogen cycle: i.e. mineralization processes within the top 5 cm of the sediment; changes in nutrient pore-water concentrations; and fluxes through the water/sediment interface. Prior to the operation, ammonia was the... |

| L'ouvrage que Verger (1968) a consacré au littoral français en général et au Bassin de Marennes-Oléron en particulier est certainement le plus important document dont nous disposons dans le domaine morpho-sédimentaire. Dans cette étude, l'auteur assimile le littoral charentais aux Wadden de Hollande : cette comparaison est cependant discutable, suivant les arguments développés ci-après qui montrent les principales différences entre vasières littorales charentaises et waddens hollandais. |
