Active research projects:

Biogeochemistry in the Arctic Ocean/title: Nitrogen uptake and phytoplankton productivity in the changing Arctic Ocean.

I am investigating the supply, uptake and cycling of inorganic and organic nitrogen compounds in the seasonal ice zone of the Barents Sea under different ice cover and at different seasons: from pre-bloom winter, over spring bloom conditions into the post-bloom summer.
