4.3.1 Proportion of eutrophied area The proportion of eutrophied area for the overall assessment was calculated based on the integrated assessment output shapefile at HELCOM Assessment unit level 4 (2013 Version, with updated coastal areas provided by Estonia and Denmark). The calculations were made using the ‘Calculate Geometry’ function in ArcGIS, by calculating sum by ‘Status’ attribute. The results for the whole Baltic Sea as defined by HELCOM marine area are presented in Table 10 part 1. Results for Danish coastal areas was included by adding the area covered by WFD status class “good” as category “Good” and all other WFD status classes as “Not good”. Results were also calculated for the Baltic Sea as defined by the MSFD sub-regions (Table 10, part 2), in which case areas which belong to MSFD Region “North Sea” were excluded (Kattegat and the Sound) and only MSFD region “Baltic” was used (See Figure 9).
