About Iselin Medhaug

I am a PostDoc in climate dynamics at the Geophysical Institute, University of Bergen and the Bjerknes Centre for Climate Research. My main research interest is the climate variability in the North Atlantic ocean, with focus on ocean circulation and heat transport from the tropics to the pole on time scales from years to decades.
