Atmospherically-promoted photosynthetic activity in a well-mixed ecosystem: Significance of wet deposition events of nitrogen compounds ArchiMer
Boulart, C; Flament, Pierre; Gentilhomme, V; Deboudt, K; Migon, C; Lizon, F; Schapira, M; Lefebvre, Alain.
Wet atmospheric deposition of dissolved N, P and Si species is studied in well-mixed coastal ecosystem to evaluate its potential to stimulate photosynthetic activities in nutrient-depleted conditions. Our results show that, during spring, seawater is greatly depleted in major nutrients: Dissolved Inorganic Nitrogen (DIN), Dissolved Inorganic Phosphorus (DIP) and Silicic acid (Si), in parallel with an increase of phytoplanktonic biomass. In spring (March-May) and summer (June-September), wet atmospheric deposition is the predominant source (> 60%, relative to riverine contribution) for nitrates and ammonium inputs to this N-limited coastal ecosystem. During winter (October-February), riverine inputs of DIN predominate (> 80%) and are annually the most...

Bases para el manejo integrado del recurso langosta (panulirus argus) en la zona costera sur de Pinar del Río, Cuba, II. Factores socio-económicos. OceanDocs
Piñeiro, R.; Puga, R.; González-Sansón, G..
Social-economical activities in the western area of the Batabanó gulf, southern coast of Pinar del Río are analized. The communities do not have a compression of the environmental on the resource, as well as the fragility of the coastal ecosystems. Between the negative effects over the environmental are the indiscriminate cutting, the pollution, all of them due to the ignorance of the mangove forests benefits. The economic activities are industrialists and agriculturists where the spiny lobster fishery (P. argus) is the most important. A decrease of the level of captures from 1990 to 2003, was observed. This behavior reflects the deteriorate conditions of the environment, which limit the recruitment and affect some nursery areas, as well as the...

Bases para el manejo integrado del recurso langosta (panulirus argus) en la zona costera sur de Pinar del Río, Cuba. III. Manejo integrado OceanDocs
Piñeiro, R.; González-Sansón, G.; Puga, R..
Integrated management study of the western area of Batabanó gulf, southern coast of Pinar del Río, is presented. A taxonomy of uses and of matrices relating uses and resources, were done. Uses are biological, hydrological, populational and recreational and are also included the run-offs from the coast and the research studies done in the area. Hydrological uses present a high level of interaction with other factors, showing it importance in the activities taken place in the zone. This interaction may be dangerous over the resources where the fisheries are developed. The resources studied were from the agriculture and fishery ones, woodland and bee production and the ecosystem. Lobster fishery is affected by a varied group of factors, like the volume of...

Bathymetric estimation using MERIS images in coastal sea waters ArchiMer
Minghelli Roman, Audrey; Polidori, Laurent; Mathieu-blanc, Sandrine; Loubersac, Lionel; Cauneau, François.
Bathymetric estimation using remote sensing images has previously been applied to high spatial resolution imagery such as CASI, Ikonos, or SPOT but not on medium spatial resolution images (i.e., MERIS). This choice can be justified when there is a need to map the bathymetry on large areas. In this letter, we present the results of the bathymetry estimation over a large known area, the Gulf of Lion (France), expanding over 270 x 180 km.

Behaviour and fate of urban particles in coastal waters: Settling rate, size distribution and metals contamination characterization ArchiMer
Oursel, B.; Garnier, C.; Pairaud, Ivane; Omanovic, D.; Durrieu, G.; Syakti, A. D.; Le Poupon, C.; Thouvenin, Benedicte; Lucas, Y..
The evaluation of contaminant net fluxes from the coast to the open sea requires the study of terrigeneous particles behaviour and fate. We studied the particles issued from two small coastal rivers whose waters are mixed with treated wastewater (TWW) coming from the Marseille wastewater treatment plant (WWTP) just before discharge to the Mediterranean Sea. An experimental device was developed and used to investigate particles settling rates, size distribution and metallic contamination when mixing with seawater. The particles were sampled in flood deposits of rivers and outlets during rainy periods and in the outlet water during dry periods. The flood deposits were mainly composed of 50–200 μm-sized particles, higher metals content being observed in the...

Bilan des connaissances sur la qualité de l'eau dans la zone du polder conchylicole de Bouin - Projet LEAUPOLD ArchiMer
Hatt, Philippe-jacques; Stavrakakis, Christophe; Buchet, Vincent; Dupuy, Beatrice.
Le polder conchylicole de Bouin (Vendée) est le principal bassin français de production de naissains d’huîtres creuses issus d’écloseries. Depuis 2007, et malgré l’installation de dispositifs de traitement de l’eau, des anomalies dans les élevages voire des mortalités affectent la production des écloseries et nurseries du secteur, ainsi que celle de microalgues en grand volume d'une entreprise spécialisée. Les observations des professionnels orientent la recherche de la cause de ces mortalités sur les contaminants chimiques, notamment les pesticides utilisés par l'agriculture, dont les exploitations du polder agricole, qui jouxtent le polder conchylicole. Comme l'ont montré de nombreux travaux, certains de ces produits altèrent la qualité de l’eau de mer...

Biomasa y distribución espacial del bacterioplancton en el sector norte de la plataforma continental argentina (34º S-41º S) OceanDocs
Hozbor, M.C.; Hernández, D.R.; Cucchi Colleoni, A.D.; Costagliola, M.C.; Peressutti, S.R..
The northern sector of the Argentine continental shelf (34º S-41º S) is a highly productive area that sustains important fishery resources like Argentine anchovy (Engraulis anchoita) and is characterized by the presence of frontal zones with retention of detritus and plankton. In marine environments the bacterioplankton represents one of the main components of the trophic nets and plays a key role in biogeochemical cycles. In this ecosystem biomass and bacterioplankton distribution as well as their relation to environmental variables were analyzed. The highest chlorophyll a values, not significantly related to bacterioplankton (p > 0.05), were found in frontal and coastal areas. Abundance, bacterial biomass and cell volume values ranged 0.48-5.42 x 106...

Coastal Ecosystems OceanDocs
The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango...
