Motivation: Impacts of a sea-ice-free Arctic on oceanic biogeochemical fluxes - future threat to the ozone layer?
Data:
- Observations: Ship campaign measurements of surface water and atmospheric halocarbon concentrations (CHBr3 bromoform), SST, SSS, wind
- Model: NorESM model, present-day and future projections
Method:
- Data analysis: Comparison between model and observation data for the present and analysis of future projections.
- Own model experiments with NorESM may also be possible.
Questions:
- How is the oceanic halocarbon production changing in a future climate in a sea ice-free Arctic?
- What are the impacts on ozone and radiation?
