Última CARIOZA. Comparaison des méthodes cartographiques par imagerie optique des herbiers de zostères marines de l’ouest Cotentin (Manche) 5 Aubin, S; Latry, L; Curti, C; Beguet, B; Lafon, V; Basuyaux, O; Garcia, A. Le projet CARIOZA, Comparaison des méthodes cartographiques par imagerie optique des herbiers de l’ouest Cotentin, porté par le MNHN Dinard, vise à effectuer un nouveau travail de comparaison à partir de la zone atelier du projet CIZO, avec pour objectif de confronter d’une part les méthodes d’acquisition de la donnée et d’autre part les moyens de réalisations cartographiques employées par le MNHN Dinard, le SMEL et I-SEA, expert en cartographie des habitats via une méthode de traitement semi-automatisée. Le but final de cette étude est de discriminer la méthode la plus adaptée, en termes d’acquisition de la donnée et de traitement de cette dernière, sur l’ouest Cotentin. Ces éléments de réflexion intégreront les discussions au niveau National (GT DCE Eaux...

High-resolution colour satellite imagery is used to map the morphology and to determine the longshore movements of intertidal ridge and runnel systems that characterise the Atlantic southwest coast of France. A couple of Spot images recorded during the summer of 1989 are processed to extract accurate geographical maps of the coastline defined. in this study, as the level corresponding to the lowest astronomical tide. The coastline extraction method is based on a reflectance model, providing depth measurements that were calibrated in the field. This method enables us to map the coastline regardless of the tide level above the lowest astronomical tide at the moment of the image capture. As this model can be extrapolated to a large area, hen sea water is...

In order to provide information on the production and the distribution of hydrothermal particulate and biological material produced by deep-sea hydrothermal vents, three moorings with sediment traps and currentmeters were deployed for one year in the Azores Triple Junction region. Two moorings were positioned close to two hydrothermal vent fields at the Mid-Atlantic Ridge (Rainbow, 36 degrees 14'N, 33 degrees 54'W, 2250 in depth and Lucky Strike 37 degrees 17'N, 32 degrees 17'W, 1600 in depth). A third was moored out of the influence of the Rainbow vents representing the reference of the pelagic flux in this area. At the Rainbow field, particulate flux (range 341-634 g m(-2)d(-1)) showed a high temporal variation controlled essentially by the current...
