OSPAR COMP4 thresholds for nutrients and chlorophyll

Commissioned by the Ministry of Infrastructure and Water Management, Deltares has performed a study to give insight in potential consequences of new, regionally harmonized thresholds for eutrophication in marine waters for the Netherlands. These thresholds were developed as part of the OSPAR assessment of the eutrophication status as part of the Quality Status Report 2023 on the environmental status of the North East Atlantic.
