HELCOM Datasets can be access from HELCOM Data and Map service as well as following thematic map portals:
Sea Environmental monitoring: Monitoring stations and assessment units
Sea Environmental status: Assessment status maps and results derived from monitoring data
Pressures and Human Activities: Datasets related to pressures (pollution and sources) to the Baltic Sea
Biodiversity: Biodiversity related datasets such as species distribution and protected areas.
Maritime & Response: Datasets related to maritime traffic and accident response
Maritime Spatial Planning: Datasets with relevance to MSP purposes
All available map data is accessible from all thematic map services for overlaying purposes. Each dataset is accompanied by a metadata file which describes the dataset. Users are advised to familiarise themselves with the metadata in order to better understand the quality, nature and restrictions of the data.
According to the HELCOM data and information strategy , all HELCOM monitoring data should be openly accessible online. The map service contains also datasets from sources other than HELCOM, so please consult metadata of each map layer regarding use limitations. All HELCOM datasets can be used freely given that the source is cited.
The HELCOM data and information strategy is a part of the 2013 Monitoring and assessment strategy.

HELCOM WMS service is currently created with ArcGIS Server 10.1 and enabled for multiple spatial reference systems in order to provide data within national coordinate systems used by national web map portals. The coordinate systems currently provided are:
EPSG: 3035 (ETRS89LAEA, INSPIRE/EU recommended frame of reference for geodata for Europe.)
EPSG: 4386 (WGS84)
EPSG: 32633 (WGS 84 / UTM zone 33N)
EPSG: 3857 (WGS84 Web Mercator)
EPSG: 3006 (SWEREF99TM)
EPSG: 3067 (ETRS89 / ETRS-TM35FIN)
The following web map portals are currently displaying map data from HELCOM via WMS connection:
