Areas of interest and expertise

Upper-ocean vertical mixing processes are highly important for ocean dynamics on a wide range of scales. Turbulence affects stratification and ice melt and formation, and thus also contributes to the horizontal density gradients that are important for the large-scale oceanic circulation. In addition to vertical exchange of heat and salt, nutrients for primary production and dissolved CO2 are among the other important constituents that are affected by varying vertical mixing driven by wind, tidal current shear, internal waves etc.

Field studies linking vertical processes with their driving forces and the resulting impact on biology and chemistry are important. I also work with regional- and local-scale numerical ocean modeling, including ice and biological modules, with the goal of improvement of vertical parameterizations as well as better understanding of fundamental exchange processes in Arctic regions.
