Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Castaing, P; Allen, Gp; Houdart, Michel; Moign, Y.
The objective of this study, carried out in the Gironde estuary inlet, was to determine the nature of the seaward dispersion of estuarine water and suspended sediments during a spring tide and high river flow. On June 3, 19(7, three flights were made over the inlet, at mid ebb, low tide and mid flood. The planned flight at high tide was cancelled due to adverse meteorological conditions. During each flight, thermal infrared coverage was obtained, together with black and white photographs. These data were correlated with concomitant ground mesures of current velocity, salinity, temperature and suspended sediment concentration Four types of water masses were identified during the tidal cycle: estuarine "very warm and turbid" water; estuarine "cooler and...

Le schéma général des études écologiques relatives à l'implantation des centrales nucléaires en estuaire prévoit deux étapes:  - le projet qui a pour but de préciser l'état écologique du milieu dans la zone qui subira l'influence de la centrale.  - la surveillance qui correspond à l'étude des fluctuations naturelles du milieu (variations pluri-annuelles notamment) avant la mise en service de la centrale, et des modifications du milieu après la mise en service de la centrale.  Projet et surveillance écologiques sont deux phases complémentaires d'une même étude, qui visent à mettre en évidence les règles évolutives d'un écosystème soumis aux effluents thermiques d'une centrale nucléaire. Les lois recherchées, utilisables à des fins prédictives. ne peuvent...

Etude isotopique (Sr-Nd) de l'origine des depots fins holocenes du littoral atlantique (S-O France)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Parra, M; Trouky, H; Jouanneau, Jm; Grousset, F; Latouche, C; Castaing, P.
The fine-grained sediments of the West Gironde mud patch derive mainly from materials supplied via the Gironde estuary. Between 1500 and 1200/1300 years BP and 300/400 years BP and the present day, the Sr isotopic and chemical compositions of the estuarine silty clay inputs are the same. In contrast, these compositions were different during the period 1200/1300 to 300/400 years BP These variations probably reflect anthropogenic activities including cultivation and agriculture, in the Garonne and Dordogne drainage basins during the medieval period. Modern silty clay sedimentation in the mud flats of the Marennes-Oleron basin and Perthuis Breton is characterised by the occurrence of important quantities (between 40 and 90 % of the total) of detritus that...

Variabilité du panache turbide de la Gironde par télédétection. Effets des facteurs climatiques
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Froidefond, Jm; Jegou, Anne-marie; Hermida, J; Lazure, Pascal; Castaing, P.
The Gironde estuary (France) discharges to the ocean an important amount of suspended particulate matter in the form of turbid plumes. The surface plume is more particularly studied from coastal oceanographic surveys and NOAA/AVHRR satellite data collected during a French programme of coastal oceanography (PNOC-Atlantic). The AVHRR reflectances are atmospherically corrected according to an algorithm based on the clear water concept. The comparison with suspended sediment concentrations are realised by direct and indirect calibrations. The correlations obtained show that at a same concentration the reflectance varies, probably because of varying particle (floc) size and composition. The shape and the surface measured from low resolution (4 km x 4 km) and...

Evolution des propriétés mécaniques de matériaux composites verre/polyester gelcoates en milieu marin
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Castaing, P; Tsouvalis, N; Lemoine, Lionel.
Glass-fiber reinforced polyester composites with gelcoat are widely used in nautical construction despite the lack of knowledge concerning their durability when immersed in water. This study deals especially with the influence of the osmotic process of degradation on the evolution of the mechanical properties of orthotropic materials, subjected to accelerated ageing tests. This evolution is experimentally evaluated by performing a non destructive test procedure, the vibrational modal analysis, whose results are additionally confirmed by quasi-static mechanical tests (bending and shear). Although gelcoat blistering has no effect on the mechanical properties of the structure, considerable changes are observed in the elastic moduli and in the ultimate...

La dispersion des apports de la Gironde sur le plateau continental. Données in situ, satellitales et numériques
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hermida, J; Lazure, Pascal; Froidefond, Jm; Jegou, Anne-marie; Castaing, P.
Coastal waters are generally a product of mixing between continental and oceanic originated water masses. Near river mouth areas, as in the Gironde estuary, oceanic waters are modified by the influence of freshwater discharge that introduces suspended and dissolved substances, including pollutants. Within PNOC (Programme National d'Oceanographie Cotiere) our objective is to determine the extent of the influence of the Gironde estuary on to the Aquitanian continental shelf. Several cruises for collecting hydrological data have been carried out in this area. The data of every cruise were coupled with a NOAA-11 satellite passage. The recorded images have been analysed and were compared with the results given by a 3D mathematical model. The interaction among...
