Salinity may vary from brackish water to hypersalinity depending on rainfall, evaporation and addition of fresh seawater from storms, temporary flooding, or tidal exchange. The distribution map is based on data submission by HELCOM contracting parties. Most of the submitted data is based on modelling and/or GIS analysis. Data coverage, accuracy and the methods in obtaining the data vary between countries.

Sweden: Polygons of Natura 2000 habitats 1150 Coastal lagoons based on GIS-analysis in the SAKU-projekt and modified in 2010 by METRIA. Polygon data on estuaries also from BALANCE project. Source: Swedish Agency for Marine and Water Management (HaV). Data quality: Data quality and habitat definitions vary between countries. Data is often based on modelling and ground-truthing has not always taken place. The dataset was approved by all HELCOM Contracting Parties in the HOLAS II Ecosystem component data review process during first quarter of 2017 after corrections from Germany and Poland. Attribute information: Raster value representing presence (1) or absence (0) of coastal lagoons.
