  • Summary Under the Convention on Wetlands (Ramsar, 1971), each Contracting Party undertakes to designate at least one wetland site for inclusion in the List of Wetlands of International Importance (the “Ramsar List”). There are over 2,000 “Ramsar Sites” on the territories of over 160 Ramsar Contracting Parties across the world. For more information on the Convention, please visit the Ramsar website http://www.ramsar.org. The Ramsar Sites Information Service (RSIS) provides online information on wetlands that have been designated as internationally important. All Site information is provided by the Contracting Parties to the Convention and is managed by the Ramsar Secretariat. Responsibility for the accuracy of the data lies with the Administrative Authority of the Party in which the Ramsar Site is located. The Ramsar Secretariat provides open access to the RSIS and its data, to promote the conservation and wise use of wetlands. If you are interested in an overview of the Ramsar Sites network, or are looking for information on a specific Site, please visit the Explore Sites page. You will find: a searchable database of Ramsar Sites, which holds information on the wetland types, ecology, land uses, threats, hydrological values of each Site as well as spatial information downloadable copies of Ramsar Information Sheets (RISs) for each site which have been provided by the Contracting Parties , including maps and supplementary information, Site summaries, and exportable data sets; and digital (GIS) boundaries of Sites, where available. For any further questions, comments or other inquiries about the RSIS, please contact the Ramsar Secretariat at ramsar@ramsar.org. Description This dataset displays Ramsar site polygon areas downloaded from https://rsis.ramsar.org/ in 17.2.2016. The dataset was subsetted by selecting only the sites that are withing Baltic Sea drainage area and projected to ETRS89LAEA by the HELCOM Secretariat.

  • Summary Extraction of the Natura 2000 spatial dataset by EEA (https://www.eea.europa.eu/data-and-maps/data/natura-12). The dataset is "Natura 2000 public end 2020" spatial dataset (Published: June 2021) downloaded from EEA website in 1 December 2021 and extracted areas that are within or proximity of the Baltic sea coastline dataset. Description Natura 2000 is the key instrument to protect biodiversity in the European Union. It is an ecological network of protected areas, set up to ensure the survival of Europe's most valuable species and habitats. Natura 2000 is based on the 1979 Birds Directive and the 1992 Habitats Directive. The green infrastructure it provides safeguards numerous ecosystem services and ensures that Europe's natural systems remain healthy and resilient.

  • This dataset includes assessment units in scale 1. HELCOM Marine area 2022 (No division: the whole Baltic Sea encompassing the entire HELCOM area) as defined in the http://www.helcom.fi/Documents/Action%20areas/Monitoring%20and%20assessment/Monitoring%20and%20assessment%20strategy/Monitoring%20and%20assessment%20strategy.pdf.

  • This dataset includes assessment units in scale 2. HELCOM Subbasins 2022 (Division of the Baltic Sea into 17 sub-basins) as defined in the http://www.helcom.fi/Documents/Action%20areas/Monitoring%20and%20assessment/Monitoring%20and%20assessment%20strategy/Monitoring%20and%20assessment%20strategy.pdf.

  • Input of impulsive anthropogenic sound includes impulsive events from 2011-2016 • Seismic surveys (HELCOM-OSPAR Registry; national data call submissions as lines in the folder of data) • Explosions (HELCOM-OSPAR Registry) • Pile driving (HELCOM-OSPAR Registry) • Airguns (HELCOM-OSPAR Registry) For the different event types, numeric intensity value was used to represent the pressure as categorized in HELCOM-OSPAR Impulsive noise registry. All nationally reported seismic surveys were given intensity values “Very low” (0.25) - Very low (0.25) - Low (0.5) - Medium (0.75) - High (1) The impact distance has not been taken into account due to the different nature of separate datasets used for the pressure layer. We acknowledge that e.g. pile driving and airguns may impact up to 20 km from the source event. The spread of the sound wave depends on the sound frequency, water salinity, temperature and density.

  • This dataset includes assessment units in scale 4 for eutrophication. HELCOM Subbasins with coastal WFD water types of water bodies 2022 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and off-shore areas and division of the coastal areas by WFD water types or water bodies) as defined in the http://www.helcom.fi/Documents/Action%20areas/Monitoring%20and%20assessment/Monitoring%20and%20assessment%20strategy/Monitoring%20and%20assessment%20strategy.pdf.

  • Summary Unesco Man and the Biosphere (MAB) Biosphere reserves in the Baltic Sea area (in 1998) and UNESCO World Heritage Sites. Description Dataset contains the Unesco Man and the Biosphere (MAB) Biosphere reserves in the Baltic Sea area (in 1998). Biosphere Reserves are areas of terrestrial and coastal ecosystems promoting solutions to reconcile the conservation of biodiversity with its sustainable use. They are internationally recognized, nominated by national governments and remain under sovereign jurisdiction of the states where they are located. Biosphere reserves serve in some ways as 'living laboratories' for testing out and demonstrating integrated management of land, water and biodiversity. The source of this data set was 'Baltic Pipeline System: Environmental Impact on the Baltic Sea' by Tacis services DG IA, European Commission. The dataset has later been amended with UNESCO World Heritage Sites. See attribute table for details. For more information about marine protected areas in the Baltic Sea, see: http://www.helcom.fi/environment2/biodiv/en_GB/bspas/.

  • The layer depicts the pressure of hazardous substances in the Baltic Sea, based on the data from the HOLAS 3 integrated hazardous substances assessment. The methodology utilizes the integrated status values available for each HELCOM assessment unit on level 3. The results are based on multiple hazardous substances groups integration, done through the CHASE tool. The integrated assessment assess the hazardous substances status in biota, water and sediment, and final result in based on the worst status. As the SPIA is carried out using a 1x1km grid and the Integrated hazardous substances is assessed on vector-based HELCOM assessment units, the vector data is rasterized. First, the vector data is rasterized to 100x100m resolution, and thereafter it is aggregated to 10x10km grid using a mean value. A 10 km grid is used in order to make the gradients between assessment units slightly smoother and finally values are converted to 1x1 km resolution. Please see "lineage" section below for further details.
