Tittel: The OSPAR Comprehensive Procedure for the Norwegian West Coast - Eutrophication Status

The Norwegian west coast from Lindesnes to Stad has been classified according to the OSPAR Common Procedure. Compared to the previous assessment in 2002, this classification is based on new data on nutrient load and more data on oxygen conditions, hard bottom fauna and flora (especially sugar kelp) as well as other data from a number of recipient studies. 21 areas have been classified. The two striking features are overall increased nutrient loads and lack of monitoring data. The existing data has been of very varying quality, but 4 Problem Areas, 14 Potential Problem Areas and 3 Non Problem Areas have been identified. The high number of Potential Problem Areas is caused by the combination of increased nutrient load and insufficient data for assessment of effects
There is a definite need for systematic monitoring with a long perspective, especially of Category II-III effects, and with focus on selected Potential Problem Areas.
