Abstract
The Arctic Ocean (AO) will likely become ice-free in summer within the next two decades. This will change light conditions for primary production. Parts of the AO where primary production is presently light limited will be controlled also by nutrient availability in the future. It is therefore of interest to study horizontal and vertical transports of nutrients in the AO and to assess the relative importance of the different nutrient sources. In the present study we have used the coupled system SINMOD to quantify nutrient transport and mixing in the AO. The import and export of nutrients have been calculated and compared with similar results based on analysis of observational data. Vertical transport and mixing of nutrients in different parts of the Arctic are also quantified and the relative importance of the different processes are assessed.
