Degree MSci
Job type Research
Research Area(s) Physical Oceanography , Physical Oceanography
Research Activities My research activities revolves around the use of remote sensing in oceanography to determine the existing relationships between physical and biological processes. In particular, I use data from the NOAA weather satellites to measure sea surface temperatures as an indicator of physical processes (currents, upwellings, etc.) and ocean color data (SeaWiFS, MODIS, MERIS) to measure chlorophyll concentration and evaluate phytoplankton productivity. My work is conducted in the Quebec coastal waters (St. Lawrence estuary and gulf) and in the canadian arctic (Hudson Bay, Baffin Bay, Beaufort Sea). Because the optical properties of these areas are complex, there a continous need to participate to oceanographic campains (NOW, CASES, Arcticnet, IPY) to validate the remote sensing data. These projects are supported by the IML remote sensing laboratory which operates receiving stations allowing a complete coverage of the canadian coastal waters.

Mes activités de recherche principales portent sur les utilisations de la télédétection en océanographie afin de déterminer les relations existants entre les processus physiques et biologiques en milieu marin. En particulier, j'utilise les données des satellites météorologiques NOAA afin de calculer la température de surface de la mer en tant qu'indice des processus physiques (courants, remontées d'eau, etc) et les données du satellite SeaWiFS pour déterminer la concentration de chlorophylle et évaluer la productivité phytoplanctonique. Mes travaux sont réalisés dans les eaux côtières du Québec (estuaire et golfe du Saint-Laurent) ainsi que dans l'arctique canadien (baie d'Hudson, baie de Baffin, mer de Beaufort). Comme les propriétés optiques de ces eaux sont complexes, il existe un besoin continuel de participer à des campagnes océanographiques (NOW, CASES, Arcticnet) afin de valider les données de télédétection. Ces divers projets de recherche sont supportés par le laboratoire de télédétection de l'IML qui opère des stations de réception d'images permettant ainsi de couvrir l'ensemble des eaux côtières canadiennes.
