Latest evaluations from the Baltic Sea region
About
This HELCOM indicator web page provides the latest available indicator evaluations from the Baltic Sea region. These evaluations offer information about the status of the Baltic Sea marine environment, as well as on pressures or drivers that can be useful in understanding the status of the evaluations. Indicators can be filtered by type, category and policy relevance.
See the Indicator Manual for more information about the development and use of the indicators, as well as for a summary of the current regionally agreed an scientifically supported threshold values.
