Bubbles in ocean water

The colour of the ocean has long been used to estimate the abundance of phytoplankton in the ocean and other key variables. Such applications using satellite remote sensing have provided us with global and dynamic maps of phytoplankton abundance and revolutionised our understanding of the interaction between physics and biology. About a decade ago satellites gained new spectral bands allowing us to examine phytoplankton chlorophyll fluorescence, a very small amount of light that is emitted by chlorophyll within phytoplankton.

With these new tools, we can now map globally the efficiency of phytoplankton chlorophyll fluorescence. From laboratory studies, we know that such measurements are sensitive indicators of the photophysiological state of phytoplankton and could provide diagnostics of their growth condition or health. However, pinpointing the main source of the variability has been difficult. At the same time, we are continually seeking to obtain more information about oceanic processes using ocean color. New techniques involving anomalies in ocean color may provide such insights. However, again, the exact cause of these anomalies are difficult to pinpoint.

Professor Yannick Huot

Professor Huot is visiting from University of Sherbrook in Quebec Canada. Yannick Huot obtained his B.Sc. in physics at the Université Laval (Québec, Canada) and his M.Sc. and Ph.D. in oceanography at Dalhousie University (Halifax, Canada). After pursuing post-doctoral studies at the Observatoire Oceanologique de Villefranche (France), he joined the Université de Sherbrooke (Québec, Canada), where he is professor and holds the Canada Research Chair in Earth Observation and Phytoplankton Ecophysiology in the Department of Applied Geomatics. His field of research covers ocean optics and remote sensing as well as phytoplankton photophysiology. His research involves using numerical modelling, remote sensing, laboratory and field work to understand how phytoplankton are responding to environmental changes. Having crossed the “salty divide”, he is also pursuing work in phytoplankton ecology in lakes.

Professor Huot received this prestigious fellowship to work with the Remote Sensing & Satellite Research Group (RSSRG) in the Faculty of Science and Engineering.
