Eutrophication assessment of the Baltic Sea Protected Areas by available data and GIS technologies

► Analysis of the eutrophication status of Baltic Sea Protected Areas. ► Application of the HELCOM Eutrophication Assessment Tool (HEAT). ► Use of modelled data on atmospheric nitrogen deposition (EMEP data). ► Both datasets provide comparable first eutrophication estimates on a broad scale. ► Further assessments and empirical data needed e.g. to develop management strategies.
