In the proposal, we are aiming to use the state-of-the-art Norwegian Earth System Model (NorESM) to project the future dispersion patterns of radionuclides in the North Atlantic-Arctic Ocean and to assess the associated radioecological risks with the consideration of different climate change scenarios and potential sources of radioactive contaminants defined by the end users, i.e. Nordic nuclear safety authorities.

The outcome of this project will improve our knowledge of future (radioactive) pollutant dynamics in the North Atlantic and will provide practical experiences to the Nordic authorities and institutes for better nuclear preparedness and radioecological assessment in the future.

In addition to the expected scientific outcome of the project, an interdisciplinary network will be established, connecting the Nordic nuclear safety authorities and institutes, numerical-modelling groups, and ocean-observation laboratories.
