Idier, Deborah / Paris, Francois / Le Cozannet, Goneri / Boulahya, Faiza / Dumas, Franck - 2017Sea-level rise (SLR) can modify not only total water levels, but also tidal dynamics. Several studies have investigated the effects of SLR on the tides of the western European continental shelf (mainly the M2 component). We further investigate this issue using a modelling-based approach,...Contributeur (s):

Andrefouet, Serge / Thomas, Yoann / Dumas, Franck / Lo, Cedrik - 2016Spat collecting of the black lip oyster (Pinctada margaritifera) is the foundation of cultured black pearl production, the second source of income for French Polynesia. To understand spat collecting temporal and spatial variations, larval supply and its origin need to be characterized. To achieve...Contributeur (s):

Bennis, Anne-claire / Ardhuin, Fabrice / Odaka, Tina / Dumas, Franck - 2016A numerical model coupling the three-dimensional oceanic circulation, thanks to the MARS3D model, and the sea state computed by the WAVEWATCH III model, is developed in order to study the hydrodynamic of the nearshore zone. The main principle of the coupled model based on the coupler PALM and the...Contributeur (s):

Bennis, A. -c. / Dumas, Franck / Blanke, Bruno - 2016The mechanics of rip currents are complex, involving interactions between waves, currents, water levels and bathymetry that pose particular challenges for numerical modeling. Horizontal turbulent diffusion in a rip system is difficult to measure using dye dilution or surfzone drifters, as shown by...Contributeur (s):

Duffa, Celine / Du Bois, Pascal Bailly / Caillaud, Matthieu / Charmasson, Sabine / Couvez, Celine / Didier, Damien / Dumas, Franck / Fievet, Bruno / Morillon, Mehdi / Renaud, Philippe / Thebault, Herve - 2016The Fukushima nuclear accident resulted in the largest ever accidental release of artificial radionuclides in coastal waters. This accident has shown the importance of marine assessment capabilities for emergency response and the need to develop tools for adequately predicting the evolution and...Contributeur (s):

Couvelard, Xavier / Dumas, Franck / Garnier, Valerie / Ponte, Aurelien / Talandier, Claude / Treguier, Anne-marie - 2015Recent realistic high resolution modeling studies show a net increase of submesoscale activity in fall and winter when the mixed layer depth is at its maximum. This submesoscale activity increase is associated with a reduced deepening of the mixed layer. Both phenomena can be related to the...Contributeur (s):

Pineau-guillou, Lucia / Dumas, Franck / Theetten, Sebastien / Ardhuin, Fabrice / Lecornu, Fabrice / Le Roux, Jean-francois / Idier, Deborah / Muller, Heloise / Pedreros, Rodrigo - 2015The pre-operational system PREVIMER provides coastal observations and forecasts along French coasts. It provides, among other variables, currents, sea levels, surges and waves. This paper describes the development and validation of a high temporal (15 minutes) and spatial (250 m) resolution...Contributeur (s):

Dumas, Franck / Pineau-guillou, Lucia / Lecornu, Fabrice / Le Roux, Jean-francois / Le Squere, Bruno - 2015Pre-operational system PREVIMER provides with coastal observations and forecasts along French coasts: currents, waves, sea levels, temperature, salinity, primary production and turbidity. These marine environmental data come from in situ observations, satellite images, and numerical models. They...Contributeur (s):

Theetten, Sebastien / Thiebault, Benoit / Dumas, Franck / Paul, Julien - 2015A software called BathyMeshGridTools is proposed to facilitate the construction of gridded bathymetry data for hydrodynamic ocean models from global to coastal scales. These tools consist of a graphical interface written in Java and a computational core written in FORTRAN, which are freely...Contributeur (s):

Lecornu, Fabrice / Pineau-guillou, Lucia / Dumas, Franck / Le Traon, Pierre-yves / Gohin, Francis / Menesguen, Alain - 2015Our coastal zones are subject to increasing anthropogenic pressure. Monitoring systems are required to protect them, prevent or mitigate risks and to ensure a sustainable management of their resources. PREVIMER is a partnership between Ifremer (French Research Institute for Exploitation of the Sea...Contributeur (s):
