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.
