The PREVIMER demonstrator is designed for a wide audience, including those who want to obtain short term coastal environmental forecasts for the Channel, Atlantic and Mediterranean coasts, be it for private or professional purposes.

Upon building a new waste pool for waste from oyster farming, a zostera noltii seagrass meadow was destroyed by sediment deposits. This site is located in the Arcachon basin and has been monitored since 2005 in order to evaluate the impact this of this work and the recolonisation of the site by benthic macrofauna.

The effect of Maerl extraction on Benthic Communities in the Glénan Archipelago.

The observation of the increase in Carbon Dioxide (CO2) content in the atmosphere certainly significantly influenced the emergence of questioning, on the part of both the scientific community and society as a whole, when faced with global and regional climate changes. Within this context, measuring CO2 flow between the ocean and the atmosphere has become a priority for the oceanographic community. This flow has been found to be highly variable in, in both spatial and temporal terms. This means that flows can be measured independently of oceanographic campaigns. Systems have been developed to be used on ships of opportunity or on Lagrangian or Eulerian tracers. The CARIOCA buoy is automated and designed to measure CO2 concentration at the surface of the ocean in order to qualify the exchanges between the atmosphere and the ocean. The buoy can be either drifting or fixed. It is 2m high and includes : • 1 salinometer • 1 fluorometer • 1 CO2 sensor • 1 anemometer • 2 temperature sensors (air and sea) It is also equipped with an ARGOS transition module and an electric supply module which powers the buoy for year, taking measurements every hour.

Sea bed sediment maps for the 4 marine sub-regions prepared as part of the initial evaluation of the MSFD (Marine Strategy Framework Directive).

Physiographic domains map at 1 : 500 000 of the French metropolitan EEZ produced in the work-package 4 (sea-floor geology / geomorphology) of the European project EMODnet Geology. This version of the dataset corresponds to the phase IV of the project.

Geomorphological analysis of the continental slope of the Bay of Biscay based on a 100m Data Terrain Model (DTM). This DTM is a synthesis of data acquired during sea surveys ZEE 1, ZEE 2, Sedimanche, Sedifan 1, Sedifan 2, EssNaut 2009, EssReson08, ValidOp, BOBGeo 1, BOBGeo 2, EssInf.
