  • This dataset contains all TBT in biota monitoring station locations, observed matrix, biota matrix and monitored species as reported to HELCOM secretariat by HELCOM Contracting Parties by 2016.

  • Regional hunting numbers for Ringed seals 2011-2014.

  • Introduction of radionuclides is based on HELCOM MORS Discharge data from 2011 to 2014. The isotopes taken into account were: Cesium-137, Strontium-90, and Cobalt-60. The decay-corrected annual average of the sum of the radionuclide discharges (in Bq) were calculated for the pressure. 10 km buffer with linear decreasing function was used to represent the impact distance from the nuclear power plant outlets.

  • Regional hunting numbers for Grey seals 2011-2014.

  • This dataset contains all PAH in seawater station locationsas reported to HELCOM secretariat by HELCOM Contracting Parties by 2016.

  • HOLAS II data set on Nuclear power plants discharge water outlets (name, delta temperature of water discharge, heat load) for 2011-2015. The coverage of the data set is full, except for the Leningrad power plant the data is not available.

  • Dataset represents the radioactive discharges from nuclear facilities in the Baltic Sea area. Data includes isotopes CS137, CO60 and SR90 Aquatic discharges in 2011-2014 with decay corrections.

  • Dataset represent urban land use (urban areas) around Baltic Sea coast. The resolution of the data is 250 m x 250 m. The dataset is constructed from CORINE Land Cover (CLC) 2006 for EU countries and from Open street map (OSM) open source data in Russia. Dataset is based on data collated for the HELCOM Second Holistic Assessment of the Ecosystem health of the Baltic Sea. The dataset covers the whole catchment area of the Baltic sea.

  • Broad-scale habitat maps for the Baltic Sea have been produced in the EUSeaMap project in 2016. For German and Estonian marine areas, national (more accurate) datasets were used. German data included both substrate and light information (division into infralittoral/circalittoral). Estonian data included only substrate and the division into light regimes was obtained from the EuSeaMap data. Here, the habitat class “infralittoral mixed substrate” includes classes “mixed sediment” of the original data, in the infralittoral zone. The original polygon maps have been converted to 1 km x 1km grid. The scale of the substrate data used in broad-scale habitat maps varies from 1:250 000 to 1:1M (data from EMODnet Geology). Coarser resolution data has been used in areas, where 1: 250 000 substrate data has not been available. Due to different scales used, the habitat classes may show different sized patterns in different areas.

  • This dataset contains all PBDE in sediment monitoring station locations as reported to HELCOM secretariat by HELCOM Contracting Parties by 2016.
