Accumulation des sels nutritifs dans un sédiment lagunaire et environnement hydrodynamique
Provedor de dados: 5
Autores: Gomez, E; Millet, B; Picot, B.
The Mejean-Perols Lagoon is situated on the French Mediterranean coast. It is a small (747 ha) and shallow (70 cm) lagoon. Some treated effluent from Montpellier flows into this hypereutrophic lagoon. The cartography of C, N and P concentrations in the sediment was studied based on 35 bottom samples. The nitrogen and organic carbon concentrations were more or less homogeneous, the highest concentrations being found in the middle of the lagoon. The phosphate was principally bound onto the sediment in the west zone. The observed distribution was independent of grain size, the distribution of which was rather homogeneous. In this lagoon water circulation is wind induced. Four different water flow structures were observed, as functions of the prevailing winds...

Métaux traces dans les sédiments d'une lagune méditerranéenne : l'étang de Thau
Provedor de dados: 5
Autores: Pena, G; Picot, B.
Analyses of mineralogy, granulometry and chemistry - aluminium,cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, zinc, organic carbon, total nitrogen and phosphorus - are carried out in a Mediterranean lagoon: Etang de Thau. Shell-fish breeding and tourism make the Thau basin an important place for studying the impact of pollution within a lagoon environment. The spatial distribution of the metallic elements is related to the fine fraction (&lt; 63-mu-m) and to the organic matter concentration of the sediment. Multivariate analysis gives a global picture of the incidence of micropolluants. It reveals a boarder zone poor in metals and organic matter which is greatly eroded by the bottom current. Several zones in the north and centre of the...
