Marine Ecosystem Services (MARECOS) is an interdisciplinary study that provides relevant information for national, Nordic and international ecosystem services assessments and valuation in the implementation of marine policy.

This report aims to provide suggestions on how ecosystem condition assessments, being based on the Marine Strategy Framework Directive (MSFD), and the HELCOM indicator based assessments for the Baltic Sea, could be used for the assessment of ecosystem services.

By describing the potentials of linking data and knowledge describing the status of marine ecosystems and water quality to the values of the services and goods provided, the report offers useful information for policy and decision makers in the domain of the marine and aquatic policies around the Baltic and in the Nordic countries.
