Research interests:

As a researcher, I study the biogeochemistry of polar oceans, with a particular interest in primary productivity and more broadly about the organic and inorganic carbon cycle. I have a geographically wide interest of the Arctic and Southern Ocean, from frontal jets and eddies, the high-nutrients low-chlorophyll regions, the sea ice covered areas, to the more coastal domain, including polynyas, and sea ice.

Defense: March 30th 2011, Rimouski, Canada

PhD project title:

Seasonal variation of energy and pollutants in the Barents Sea pelagic food web.

PhD project description:

This study aims to quantify the seasonal changes in species specific energy content, using bomb calorimetry, within and across trophic levels (macrozooplankton and fish). We aim to assess potential “critical windows”, i.e. when organisms are in a sub-optimal state and therefore more susceptible to stress, such persistent organic pollutants (POPs). We will also evaluate how seasonal energy content and pollutant levels of prey will impact the top-predators in the system, particularly seabirds. In addition, tissue specific samples will be taken for POP concentration, to study seasonal remobilization in key marine organisms.

Research interests:

Marine plankton ecology and flux of organic matter

Main focus: Fate of primary production through vertical carbon export and regulation and physical-biological coupling influencing production and export.

I started my career in fjords, investigating how the pelagic plankton community regulated vertical flux of organic matter, seasonality, and the impact of advection on fjord ecology. Since 2000, I have worked in the Arctic seasonal ice zone on how the physical environment impacts plankton productivity and communities and the resulting vertical flux of organic matter. I have used short term sediment traps for flux studies, experimental studies on particle attenuation and modification, and physical-biological coupled modeling for up-scaling to larger temporal and spatial scales, as well as to evaluate specific processes and interactions.
