Research

Research interests:

  • The role of the northern seas in climate - past, present, future
  • The (possible) interannual to decadal predictability of climate 
  • Structure and variability of ocean circulation
  • Arctic sea ice cover, how and why it changes
  • Barents Sea ice cover, climate, and ecosystem
  • Open ocean convection
  • Mesoscale eddies and frontal dynamics, incl. “spiral eddies”

using theory, observations, and models.
