International audience ; The study aims at developing new oceanographic products in order to defi ne seascapes describing synthetic abiotic patches. HYbrid Coordinate Ocean Model (HYCOM) outputs were used in the French Mediterranean Sea Exclusive Economic Zone (EEZ), to calculate Essential Oceanic Variables (EOVs) and derived EOVs. A partitioning method was then applied on EOVs in order to fi nd dynamic regional structures and generate a dynamical mosaic of the EEZ's environmental conditions. An example of these products defi ning Geographic Units under the European Union Marine Strategy Framework Directive (MSFD) French assessment of marine waters is presented.

International audience ; As part of the energy transition, the French government is planning the construction of three offshore wind farms in Normandy (Bay of Seine and eastern part of the English Channel, northwestern France) in the next years. These offshore wind farms will be integrated into an ecosystem already facing multiple anthropogenic disturbances such as maritime transport, fisheries, oyster and mussel farming, and sediment dredging. Currently no integrated, ecosystem-based study on the effects of the construction and exploitation of offshore wind farms exists, where biological approaches generally focused on the conservation of some valuable species or groups of species. Complementary trophic web modelling tools were applied to the Bay of Seine ecosystem (to the 50 km 2 area covered by the wind farm) to analyse the potential impacts of benthos and fish aggregation caused by the introduction of additional hard substrates from the piles and the turbine scour protections. An Ecopath ecosystem model composed of 37 compartments, from phytoplankton to seabirds, was built to describe the situation " before " the construction of the wind farm. Then, an Ecosim projection over 30 years was performed after increasing the biomass of targeted benthic and fish compartments. Ecological Network Analysis (ENA) indices were calculated for the two periods, " before " and " after " , to compare network functioning and the overall structural properties of the food web. Our main results showed (1) that the total ecosystem activity, the overall system omnivory (proportion of generalist feeders), and the recycling increased after the construction of the wind farm; (2) that higher trophic levels such as piscivorous fish species, marine mammals, and seabirds responded positively to the aggregation of biomass on piles and turbine scour protections; and (3) a change in key-stone groups after the construction towards more structuring and dominant compartments. Nonetheless, these changes could be considered as limited impacts of ...

Durant la dernière décennie, plusieurs états des lieux et, en particulier, laconférence nationale de santé de 1997 ont attiré l'attention des pouvoirspublics sur la santé des enfants et des adolescents. Prenant acte de cettepriorité, la Caisse nationale d'assurance maladie des professions indépendantes(Canam) a défini avec l'Inserm un programme d'expertises collectivesciblé sur les pathologies de l'enfant qui sont en augmentation (obésité, troublesmentaux, asthme{). À l'issue d'une analyse exhaustive des données de lalittérature au niveau international, les experts ont défini des recommandationspour améliorer le dépistage et la prévention de ces pathologies.La Canam a également sollicité l'Inserm pour un bilan des connaissances surles méthodes en matière d'éducation pour la santé utilisées auprès des jeunesdans le contexte national et international.Tirant profit de l'ensemble de ces travaux et de ceux menés à la demande de laMission interministérielle de lutte contre la drogue et la toxicomanie (Mildt),de la Caisse nationale d'assurance maladie des travailleurs salariés (Cnamts)et de l'Institut national de prévention et d'éducation pour la santé (Inpes) surles risques liés à la consommation d'alcool chez les jeunes, l'Inserm a récemmentproposé à la Canam un approfondissement des recommandations élaboréespar les groupes d'experts concernant la prévention de l'obésité, destroubles mentaux ainsi que du risque alcool chez les jeunes dans le but deproposer quelques actions bien définies de prévention et d'éducation pour lasanté.Sous l'égide de l'Inserm, un groupe de travail a été constitué, rassemblantplusieurs scientifiques des expertises citées ainsi que des acteurs des administrationset organismes ayant en charge l'élaboration des politiques publiques.Les troubles pris en considération par le groupe de travail représentent unepréoccupation de santé publique en raison d'une prévalence élevée qui tendencore à augmenter.
