| Les Objectifs de cette étude sont:1. Réactualiser la chaine de modélisation des têtes de bassins aux zones côtières et faire ainsi dialoguer le modèle du bassin de la Seine (Seneque/Riverstrahler) avec un modèle Estuaire/Baie de Seine (Mars 3D).2. Observer les effets, sur la basse Seine et l'estuaire en particulier, des nouveaux traitements dans les stations d'épuration du bassin.3. Quantifier les flux d'azote à la zone côtière par rapport à ceux du phosphore et de la silice.4. Synthétiser les données REPHY et RHLN pour valider l'indicateur ICEP développé au cours de la phase précédente de Seine-Aval, en cherchant à comprendre les déterminismes de la toxicité des blooms algaux.5. Construire des scénarios futurs permettant de tester, grâce au modèles,... |

| L’objectif général du projet OGIVE est d’acquérir des connaissances sur le fonctionnement des écosystèmes conchylicoles de Basse-Normandie dans le but d’établir une plateforme de données communes à l’ensemble des partenaires du projet. Ces connaissances sont ensuite utilisées pour développer des outils permettant de fournir des avis et expertises aux gestionnaires du Domaine Public Maritime. Le projet a ainsi pour objectif de contribuer au développement durable de la filière conchylicole en Basse-Normandie en optimisant la production conchylicole et en préservant la qualité environnementale des écosystèmes qui supportent cette activité. Le projet OGIVE a été structuré initialement autour de trois actions : 1) Acquisition de données : cette action a le... |

| The general purpose of assessment is to provide decision-makers with the best valuable data, information, and predictions with which management decisions will be supported. Using case studies taken from four scientific projects and dealing with the management of marine bivalve resources, lessons learned allowed identifying some issues regarding assessment approaches. The selected projects also introduced methodological or institutional frameworks: ecosystem approach to aquaculture (EAA), system approach framework (SAF), marine spatial planning (MSP), and valuation of ecosystem services (ES). The study on ecosystem services linked ES to marine habitats and identified ES availability and vulnerability to pressures. The results were displayed as maps of... |

| The general trend in ecosystem modelling is to improve the spatial resolution by shifting from rough box-models to fine 3D models. Despite the continuous speeding-up of computing, 3D models involving numerous state variables may remain intractable, especially for parameter calibration, when processes with long half-life periods (i.e, from years to decades) are introduced, such as the behaviour of organic matter in sediment and population dynamics of benthic species. In these cases, a first approach can be provided by fast-running box-models, if they take into account the most crucial hydrodynamic properties of the system. In a macrotidal shelf sea such as the English Channel, the long-term horizontal transport can be summarized by the tidal residual... |

| The ability of marine invertebrate larvae to control their vertical position shapes their dispersal pattern. In species characterized by large variations in population density, like many echinoderm species, larval dispersal may contribute to outbreak and die-off phenomena. A proliferation of the ophiuroid Ophiocomina nigra was observed for several years in western Brittany (France), inducing drastic changes on the benthic communities. We here studied the larval vertical distribution in this species and two co-occurring ophiuroid species, Ophiothrix fragilis and Amphiura filiformis, in two contrasting hydrodynamic environments: stratified in the bay of Douarnenez and well-mixed in the bay of Brest. Larvae were collected at 3 depths during 25 h within each... |
