Monitoring and Assessment

Monitoring is a well-established function in HELCOM. Monitoring of physical, chemical and biological variables of the Baltic Sea open area started already in 1979 and monitoring of inputs of nutrients and hazardous substances was initiated in 1998. Today there are several agreed HELCOM monitoring programmes covering sources and inputs of human pressures and various variables reflecting the state of the environment. 

The HELCOM monitoring programmes are the source of data for indicator-based assessments of the state and pressures on the marine environment as well as the analysis of long-term trends. The first HELCOM period assessment was published in 1986. Today, HELCOM regularly carries out thematic and holistic assessments to evaluate progress towards the goals and objectives set for the Baltic Sea environment. The HELCOM assessment products are the basis for sound decisions to restore the Baltic Sea ecosystem, to support the implementation of the HELCOM objectives and actions, and to identify emerging environmental problems. 

Current monitoring and assessment activities are guided by the HELCOM Monitoring and Assessment Strategy  adopted in 2013. 


Monitoring programmes
and guidelines

Monitoring programmes provide a high-level overview of the parameters that are monitored and the spatial and temporal scope, as well as the degree of coordination between countries in carrying out the activity. Monitoring guidelines provide detailed instructions on how to carry out monitoring activities.



Assessment methods

The HELCOM assessment methods document the regional assessment methodologies agreed among HELCOM Contracting Parties. Scripts used in assessment methods are published and shared through GitHUB.



Research vessels
and permits

Research vessels used in HELCOM monitoring programmes are listed under this page based on data collected within BALSAM project WP5 activities (co-financed by the European Union DG Environment).
