Programme de recherche

Constitué de microorganismes photosynthétiques flottants dans l'eau, le phytoplancton est à la base de la chaîne trophique dans l'océan. Dans mon programme de recherche, je tente de comprendre comment les changements dans l'environnement du phytoplancton influencent sa croissance et sa physiologie. Mes outils vont de la télédétection par satellite à la mesure de processus moléculaires à l'intérieur des cellules.

Mots clés - Océanographie biologique, optique océanique, phytoplancton, couleur de l'océan, télédétection, fluorescence de la chlorophylle, fluorescence induite par le soleil, production primaire, photosynthèse, limnologie, observations autonomes

Projets en cours

1. Écophysiologie de la production primaire, de la croissance et de la succession du phytoplancton dans les écosystèmes aquatiques

2. Chaire de recherche du Canada sur l'observation de la Terre et l'écophysiologie du phytoplancton

3. Observatoire automatisé du plancton et des facteurs abiotiques contrôlant leur croissance dans les lacs

4. Description et validation d'un modèle couplé de fluorescence et photophysiologie du phytoplancton

5. Malina project (PI : Marcel Babin)
