Mes recherches se concentrent sur les courants et les échanges de masses d'eau opérés à l’échelle de la circulation générale océanique, ainsi que sur la dynamique des systèmes régionaux d'upwelling de bord est et leur sensibilité au couplage air-mer. J’ai mis au point et développé un outil diagnostique performant, ARIANE, disponible pour l’ensemble de la communauté scientifique et utilisé pour l'analyse de la dynamique océanique, sur la base de flotteurs numériques transportés par des champs de vitesse déduits de simulations numériques ou dérivés d'observations.

Note: The genesis of this film and its framework rely heavily on my scientific work on the Lagrangian description of the global ocean circulation, with especially an animation that was used in several scientific events: “Océan et Climat” at the Cité des sciences et de l’industrie (Spring 2011), CNRS/sagascience multimedia package about the climate system (Fall 2010), etc.

Before 2000:

Mon implication dans l’enseignement concerne la formation à l’outil ARIANE, plusieurs fois par an, pour des chercheurs individuels ou des groupes, avec le programme type suivant : accueil au LOPS, démarche d’analyse, fonctionnalités de l’outil, concepts numériques, mise en application (avec Nicolas GRIMA, ingénieur de recherche au CNRS), interprétation de premiers résultats. Cette formation dispose désormais d’un ensemble de vidéos, grâce à une interaction avec le service audiovisuel de l’UBO.
