OSPAR Common Procedure for Identification of Eutrophication Status: Application of the Screening Procedure for the Norwegian coast north of 62oN (Stad ¿ Russian border)

The Norwegian coast north of 62oN bordering the Norwegian Sea and the Barents Sea, is effectively flushed by the Norwegian Coastal Current (NCC) that flows northwards along the coast from Skagerrak and into the Barents Sea. The NCC is mixed with Atlantic water and the salinity increases as it flows along the coast. The total Norwegian inputs of nitrogen and phosphorus to this area from anthropogenic sources are about 30.000 tons of N and 3.400 tons of P. The main source of N in the southern part is agriculture whereas aquaculture is the main source for P. It is concluded that the Norwegian inputs of nutrients have a very low and not detectable effect on nutrient concentrations and budgets in coastal areas and fjords. The coastal areas and fjords of Norway north of 62oN are considered a non-problem area with regard to eutrophication.
