About
I am a physical oceanographer working mostly with observations from high latitudes. My current research focuses on water mass transformation through air-ice-sea interaction in the Nordic Seas and the Arctic Ocean. In particular, I'm interested in the transformation of Atlantic Water and the formation of dense water near the sea-ice edge, as well as in the pathways and dynamics of the boundary currents that supply the overflows across the Greenland-Scotland Ridge and thus the lower limb of the Atlantic Meridional Overturning Circulation.

Overturning circulation in the new Arctic
Arctic climate is rapidly changing, and it is currently not known how the Arctic overturning circulation is responding. ArMOC will provide comprehensive understanding of the entire Atlantic Water Boundary Current (AWBC)system around the Nordic Seas and the Arctic Ocean from observations, novel insights on Atlantic Water (AW) pathways and transformation within the Arctic Ocean and a first quantification using the approach of thermohaline stream functions.
Resilient northern overturning in a warming climate
In ROVER the researchers will observe the deep-water formation along east Greenland, both through a winter expedition on an icebreaker, using mooring across the Greenland slope, and autonomous underwater gliders. The measurement campaign will provide groundbreaking data, cruical for the understanding of the processes that supply cold, deep water to the lower limb of the AMOC.
