2. Analyse and compare national approaches per descriptor regarding geographic scales
Analyse which aggregation rules have been applied
Develop broad EU guidance for coherent geographic scales in assessment and monitoring of GES and for sets of aggregation rules and organize a debate with MS on this.

3. Current state of play lAnalysis of MS approaches
21 november 2011
Current state of play
lAnalysis of MS approaches
Electronic reporting from a limited number of MS (by mid-April)
Now completed with all submissions by 30 April
Aditionally, analysis of a selection of MS reports
Impression so far:
In general, limited specific and detailed information on geographic scaling and application of aggregation rules
National expert reviews (Art. 12) may provide additional information (expected in July)

4. Current state of play lAnalysis of RSC and other approaches
21 november 2011
Current state of play
lAnalysis of RSC and other approaches
Inventory of current practices for geographic scaling, e.g.:
HELCOM, OSPAR, ICES, WFD
Methods for defining assessment units
Methods for upscaling
Inventory of approaches for aggregation
Distinction between levels: metrics -> indicators -> criteria -> descriptors -> overall GES
Inventory of existing practices within RSC’s, WFD, etc.
E.g. one-out all-out, weighted averaging, decision trees, etc.
Identification of requirements
Pros and cons of current methods
