3. Directive requirements
Article 5(2) indicates that Member States sharing a marine region or subregion shall cooperate to ensure their marine strategies are coherent and coordinated, endeavouring to follow a common approach.
Article 8(3) indicates that Member States should “make every effort to ensure that assessment methodologies are consistent across the marine region or subregion”
Article 11(4) indicates that “specifications and standardised methods for monitoring and assessment which take into account existing commitments and ensure comparability between monitoring and assessment results, …., shall be adopted …”.

4. Assessment of GES Assessment of GES
can be undertaken at various scales within a region/subregion, depending on the nature of the topic.
can be undertaken at scales larger than a Member State’s waters of a region/subregion - reported by MS, reflecting the collective assessments made across several MS waters.
When made within a Member State waters, rules of aggregation may be needed to assess whether GES, determined at the level of the region/subregion, has been achieved or maintained.

5. MSFD regions and subregions
Draft map – March Extended coverage for Continental Shelf areas – Atlantic states

6. Defining assessment areas
These can be:
Regions (Baltic, Black)
Subregions (of NE Atlantic, Mediterranean)
Subdivisions (where formally defined)
Other informal areas
Should allow, where possible, ecosystem-based assessments:
“are determined taking into account hydrological, oceanographic and biogeographic features” (Art. 3(2)).

7. - document on general principles (Clausen et al., 2011)
MSCG 2012: Need for development of common understanding on geographic assessment scales
- document on general principles (Clausen et al., 2011)
Conclusions from 2012 reporting:
No or limited coherence between MS and between marine regions
Variety of assessment scales (spatial, temporal) and aggregation limiting comparability and coherence of assessments
Develop guidance on the application of geographic scales and aggregation rules
