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, 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):

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):

Stanisiere, Jean-yves / Mazurie, Joseph / Bouget, Jean-francois / Langlade, Aime / Gabellec, Raoul / Retho, Michael / Quinsat, Kevin / Leclerc, Emilie / Cugier, Philippe / Dussauze, Morgan / Menesguen, Alain / Dumas, Franck / Gohin, Francis / Augustin, Jean-marie / Ehrhold, Axel / Sinquin, Jean-marc / Goubert, Evelyne / Dreano, Alain - 2013The project “Risco”, supported by the “Pôle Mer” and funded by the Regional Council of Brittany, deals with specific risks of mortality of oysters, Crassostrea gigas, cultivated on the bottom, in a subtidal bay of South Brittany : the bay of Quiberon (56, France). Massive mortalities of oysters...Contributeur (s):

Bailly Du Bois, Pascal / Dumas, Franck - 2004TRANSMER hydrodynamic model simulates dispersion of dissolved substances in seawater at the scale of the English Channel and the south of the North Sea with a mesh size of one kilometre and a time step of 30 minutes. It has been qualitatively and quantitatively validated by 1400 measurement of...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):

Loubersac, Lionel / Lazure, Pascal / Dumas, Franck / Le Roux, Jean-francois / Riou, Philippe / Foucher, Eric / Guillaumont, Brigitte - 2003On the morning of the 31th October 2000, the Italian chemical tanker “Ievoli Sun” sank in the central Channel. Her cargo presented a risk of contamination for the marine environment and nearby coastal environment. From the moment the sinking was announced, Ifremer decided to implement, in almost...Contributeur (s):

Plus, Martin / Maurer, Daniele / Stanisiere, Jean-yves / Dumas, Franck - 2006Introduction and objectives of the study: Understanding the operation modes of the coastline systems requires the study of the hydrodynamics responsible for transporting the whole of the chemical and biological elements of which they are composed. The idea of maintaining a close connexion between...Contributeur (s):

Tessier, Caroline / Le Hir, Pierre / Dumas, Franck / Jourdin, F - 2008A hydrodynamic and sediment model of South Brittany is calibrated with ADCP measurements, which allow to estimate hydrodynamic forcing and concentration of suspended particulate matter. The exercise of comparison between observed and simulated concentrations reveals that turbidity is highly...Contributeur (s):
