Based on frequent sampling in 2009, the current project aims to evaluate the spatial distribution of the possible presence of eutrophication effects on the level of the benthos. These results, supplemented by existing scientific information, allow an assessment of the current eutrophication status in the BPNS. Additionally, the results enable an optimal spatial and temporal planning for future monitoring campaigns concerning eutrophication effects on benthic fauna, in the framework of the European Marine Strategy.
