PREVIMER’s main objective is to produce routine analyses and forecasts on the marine environment state in coastal zones at a range of scales (from the continental shelf to the bay) with a capacity for zooming-in to specific areas. Timescales include both retrospective analyses and short-term forecasts (96h upto 120h for wave forecasts, as delimited by detailed forecasts provided by the French National Weather Service ( Météo France) and the European Centre for Medium-Range Weather Forecasts ( ECMWF)).
The emphasis is on validating the maps produced, and their qualification by experts in the field, leading to the implementation and development of a coastal forecasting service, following the examples of meteorology, and more recently, of oceanic circulation.
For whom?
- The general public, for leisure activities (bathing, diving, shellfish harvesting, sailing, etc.),
- Professional users (shellfish farmers, fishermen, maritime transport, off-shore industries),
- Coastal management bodies (local authorities, administrations),
- Scientists (national and European cooperation),
- Environmental R&D departments (impact surveys).
 "pêcheurs à pied")
Why?
 "Tables ostreicoles avec poches, La Tremblade, 1995")
- Informing the public for leisure activities (yacht races, shellfish harvesting, etc),
- Assessing the microbiological quality of water,
- Quantifying the transport of eggs and larvae of marine organisms,
- Following-up the introduction of terrigenous matter into the environment,
- Studying the proliferation of plankton and macro-algae,
- Strengthening the maritime/military security,
- Reducing the risks of exposure to accidental pollution,
- Improving the scientific knowledge of the environment, the coastal «climatology», etc.
How?
PREVIMER associates an « In-situ and teledetection data » section with a « Modelling » section.
 "Houlographe des Pierres Noires")
Swell data recorder moored early 2008 in west of Brittany ( Pierres Noires)
PREVIMER produce modelling results on diverse themes, through the following geographic areas:
- Circulation, temperature and salinity in the English Channel and the Bay of Bisquay (MANGA), MARS3D model with a resolution of 4km over 30 levels using barotropic tide and Mercator-Ocean boundary conditions;
- Circulation, temperature and salinity in the Mediterranean Sea (MENOR), MARS3D model with a resolution of 1.2km over 30 levels;
- Circulation and temperature in the Iroise Sea, MARS2D and 3D models with a resolution od 300m for le 2D and 800m over 15 levels for the 3D;
- Circulation in the Arcachon Basin, MARS2D model with a resolution of 235m;
- Circulation in North Brittany, MARS2D model with a resolution of 250m;
- Circulation in Normandy, MARS2D moidel with a resolution of 400m;
- Primary Production in the Bay of Biscay, ECO-MARS3D model with a resolution of 4km over 30 levels;
- Primary Production around Brittany, ECO-MARS3D model with a resolution of 3km over 11 levels;
- Wave hight and sea state for the world with a main zoom over the Bay of Bisquay, the English Channel and the North Sea, WW3 model with a resolution of 3.6km (0.5° for the global model);
- Wave hight and sea state in Mediterranean sea, WW3 model with a resolution of 4km;
- Wave hight and sea state in Iroise Sea, north and south Brittany, WW3 model with a resolution of 200m including tide current informations;
- Wave hight and sea state in West Indies, French Polinesia and New Caledonia, WW3 model with a resolution of 5.5km;
- Wave hight and sea state for the Basque country, Marseille, Toulon and the Var, REF-DIF models with a resolution of 150m.
PREVIMER progressively integrates other model results with the goal of covering the maximum areas aloung the French borders and the ultramarin regions.
