Abstract: The European Water Framework Directive (WFD) requires the national classifications of good ecological status to be harmonised through an intercalibration exercise. In this exercise, significant differences in status classification among Member States are harmonized by comparing and, if necessary, adjusting the good status boundaries of the national assessment methods. Intercalibration is performed for rivers, lakes, coastal and transitional waters, focusing on selected types of water bodies (intercalibration types), anthropogenic pressures and Biological Quality Elements. Intercalibration exercises are carried out in Geographical Intercalibration Groups - larger geographical units including Member States with similar water body types - and followed the procedure described in the WFD Common Implementation Strategy Guidance document on the intercalibration process (European Commission, 2011). The Technical report on the Water Framework Directive intercalibration describes in detail how the intercalibration exercise has been carried out for the water categories and biological quality elements. The Technical report is organized in volumes according to the water category (rivers, lakes, coastal and transitional waters), Biological Quality Element and Geographical Intercalibration group. This report gives a description of the intercalibration of the different benthic assessment approaches for in coastal waters in the North East Atlantic Geographical Intercalibration Group (NEA-GIG) for types NEA 1/26 (Exposed or sheltered, euhaline, shallow waters), NEA 3/4 (Wadden sea type) and NEA 7 (Deep fjordic and sea loach systems). The benthic assessment approaches of nine European Member States (Belgium, Germany, Denmark, France, Ireland, the Netherlands, Portugal, Spain and the United Kingdom) and Norway are intercalibrated. In Spain, the competent authorities for the WFD application are the regions (‘autonomous communities’); therefore for the benthic assessment methods three regions have been considered: Basque Country, Andalusia and Cantabria (no information on Galicia or Asturias). Part D of the report describes the Germany assessment approach for the type NEA 5. This type is not shared with the rest of the Members Stares, and therefore, the Intercalibration is not possible
