| An ecophysiological deterministic model of growth, reproduction and interactions between the bivalve and its estuarine environ ment was established for the Japanese oyster Crassostrea gigas. The environmental variables used in the model are: total particulate matter, particulate organic matter, particulate inorganic matter, chlorophyll, phaeopigments, proteins, lipids and carbohydrates. Rates of clearance, filtration, ingestion, absorption and respiration along with efficiencies of retention, selection and absorption are modelled with endogenous (dry weight of the animal, energy allocation between growth and reproduction) and exogenous variables (temperature, food quality and quantity). The model simulate the temporal evolution of two compartments: somatic... |

| The lagoon of New Caledonia is subject to various pressures, including terrigenous stream inputs. Their evolution – extent, intensity – can be studied through parameters such as ocean color, depending on turbidity or phytoplankton concentration. Satellite imagery is more and more used for this purpose. As the Sentinel-2 (S2) mission, with its satellites providing ten meters-resolution images, has been recently launched, we worked on the characterisation of lagoon color using these products. After testing the performance of existing algorithms for New Caledonia, initially applied to satellites other than S2, we tried to establish a new turbidity algorithm based on field data (measures in the South-West lagoon of New Caledonia and the lagoon near Koumac in... |

| La réunion du Groupe de travail Phytoplancton ‐ Hydrologie 2012, du 17 décembre 2012, a conduit à deux recommandations. La première recommandation concerne la définition des masses d'eau turbides. En effet, la liste de masses d'eaux turbides actuellement utilisée pour l'évaluation phytoplancton n'est pas satisfaisante, car absolument pas homogène d'une région à l'autre, et souvent en contradiction avec le typologie DCE. il est donc proposé de partir de la typologie existante pour la DCE, en la nuançant d’avis d’experts dans les cas où elle n’est pas totalement satisfaisante. Cette nouvelle définition des ME turbides, réalisée selon des critères plus homogènes sur l'ensemble du littoral, sera utilisée pour la prochaine évaluation de l'indicateur... |
