more dynamic Arctic sea ice and larger open ocean areas increase the complexity of accurately predicting the transport pathways and impacts of various pollutants in the Arctic environment. These pollutants [...] project we will simulate the oceanic advection of pollutants from their sources with a global version of the sea-ice-ocean model FESOM2 with about 7 km spatial resolution in the Arctic and Nordic Seas.

The sea ice-ocean model FESOM2 will be coupled with the atmospheric chemistry transport model DEHM (Danish Eulerian Hemispheric Model), thus connecting the ocean and atmospheric

Radiative effects [...] the upper layers of the Arctic Ocean. In particular, the cold halocline layer, which separates warm Atlantic water from the upper ocean mixed layer, appears to be affected by Arctic climate change. On the [...] experiments with a coupled ocean-sea ice model (North Atlantic Arctic Ocean Sea Ice Model, NAOSIM) show a destabilisation of the halocline due to increased freezing in polynyas of Arctic shelf seas.
