The implementation of the EU Marine Strategie Framework Directive (MSFD) established at the IOW a need for scientic research, especially for the development of indicators, for habitat mapping and for the definition of Good Environmental Status (GES) in several of the MSFD Descriptors. The project will be used for the dissimination of scientic results to stakeholders like the BfN Marine Environmental Protection working group. Also, results will be presented to several national and international expert groups.
