I am a physical oceanographer working mostly with observations from high latitudes. My current research focus is on water mass transformation through air-ice-sea interaction leading to dense-water formation and on the pathways of this dense water toward the overflows across the Greenland-Scotland Ridge. In particular, I'm studying the structure, volume transport, variability, and dynamics of the boundary currents in the Nordic Seas that sustain the lower limb of the Atlantic Meridional Overturning Circulation. I have also worked with tidal currents and their seasonal enhancement by continental shelf waves in Antarctica.
