This annual statistics at 500m horizontal resolution was produced from the archived time series of MARS 3D physics model hindcast runs along French Atlantic Coast. The variable that is available here is the Kinetic Energy induced by currents caused by tide, water density gradients and action of winds. The formula used for the Kinetic Energy calculation is 0.5mv², where m is the density of seawater (1027 kg.m-3) and v is the current-induced velocity. Values are expressed in N.m-2 (Newton per square meter). In each pixel the value is an average of the values of the 40 vertical levels that are considered in the model.

Base de donnée hydrodynamique réalisée avec le modèle MARS3D et la librairie AGRIF (V10.10) le long de la façade atlantique française à la résolution spatiale de 500m et à la fréquence horaire. La mise en place de zooms avec la librairie AGRIF (http://www-ljk.imag.fr/MOISE/AGRIF/) le long de la façade atlantique a permis d’augmenter la résolution à 500m et localement à 100m (Golfe du Morbihan). Un rejeu sur cinq ans a été produit avec l’ensemble des zooms pour établir des climatologies en zone côtière à haute résolution.Une simulation de six années allant de 2010 à 2015 a été réalisée pour l’ensemble des emprises couvrant la façade atlantique.

"Abstract: " Hydrodynamic database build with the MARS3D model along the french manche and atlantic coast at high spatial (500m) and temporal (1h) resolution "Details:" Seabed habitats maps are build from statistics models which need some data that describe the physical environment of the different species. Theses environmental factors are the salinity, temperature and shear stress (from waves and current) on the sea floor. Statistics are based on realistic and inter-annual simulations from 3D ocean models.Models output are currently available at a uniform resolution of 2.5 km along the whole French coast,as a part of the PREVIMER project (http://www.previmer.org) To increase the horizontal resolution of the model to 500m grid spacing, an on-line grid refinement technique has been carried out with the AGRIF library. (http://www-ljk.imag.fr/MOISE/AGRIF/) Seven zooms (with 500m resolution) have been implemented in the 2.5 km MANGAE configuration. From this configuration, an hindcast of six years (from 2010 to 2015) has been simulated and cover the french coast from spain to pas-de-calais area : "Main features of the hindcast" Horizontal resolution : 500m Vertical resolution : 40 sigma levels Temporal resolution : 1 Hour "Available physical parameters" ◦ 2D : Sea surface height and barotropic velocities (U and V components) ◦ 3D : Temperature, Salinity and baroclinic velocities
