HELCOM spatial datasets can be access from HELCOM Map and Data service. The data is grouped to following map services, which contain several map layters:
Status assessments: Assessment status maps and results derived from monitoring data
Sea Environmental monitoring: Monitoring stations and assessment units
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
Background: Background datasets such as drainage basin, territorial waters etc.
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.

HELCOM WMS service is currently created with ArcGIS Server 10.4 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:
EMODnet biology
Swedish Water information system (VISS, available only in swedish)
The Swedish Agency for Marine and Water Management (Havsplanering, available only in swedish)
Finnish national geospatial portal (Paikkatietoikkuna, available only in finnish)
