  • Dataset contains the largest oil terminals in the Baltic Sea and the volume of oil transported through. The dataset was updated for HELCOM Assessments in 2016. The statistics cover years 1997, 2000 - 2008 (where available), and 2011-2013. The statistics for 2011-2013 were derived from Baltic Port Lists published by Centre for Maritime Studies, University of Turku. The dataset was updated for HELCOM Assessments in 2016. Attribute specification and units: YEAR1997…YEAR2013: Total (million tonnes) oil and oil products transported through the terminal during referred year.

  • This dataset contains point data describing the location of oil platforms in the Baltic Sea. The dataset is complete in Baltic sea coverage as it contains two known oil platforms.

  • The dataset contains the location of oil refineries derived from the European Pollutant Release and Transfer Register (E-PRTR). The dataset covers all HELCOM Contracting Parties except Russia.

  • 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.

  • Input of heat pressure dataset contains delta heat values from warm water discharge of - Discharge of warm water from nuclear power plants - Fossil fuel energy production. The Discharge of warm water from nuclear power plants was requested from HELCOM Contracting Parties. Average temperature change of the cooling water (°C) and amount of cooling water (m3) was used to calculate the heat load in TWh. No data on heat load was available for the Leningrad nuclear power plant; therefore the average heat load (TWh) of discharge of warm water from nuclear power plants was given. No heat load information was available for fossil fuel energy production sites. Heat load of 1 (TWh) was given to all production sites, based on average heat load of individual production site in Helsinki from recent years. 1 km buffer was used for both datasets with steep decline around the outlet. Overlapping areas were summed. Heat load from both layers were summed and the layer was normalized.

  • 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.

  • 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.

  • MORS Discharge database has been used to collate data reported by HELCOM Contracting Parties on airborne and waterborne discharges resulting from nuclear facilities in the Baltic Sea and North Sea region based on HELCOM Recommendation 26/3. The database is structured according to HELCOM Guidelines on Monitoring of Radioactive Substances (http://www.helcom.fi/Lists/Publications/Guidelines%20for%20Monitoring%20of%20Radioactive%20Substances.pdf), which specifies reporting format, database structure, data types and obligatory parameters used for reporting data under Recommendation 26/3. The database is updated and quality assured annually by HELCOM MORS EG. The discharge data is reported by national competent authorities in HELCOM Contracting Parties to data consultant (STUK, Finnish Radiation and Nuclear Safety Authority). HELCOM MORS Expert Group validates and quality assures annually all data reported to HELCOM MORS Discharge Database.

  • The dataset contains the location of fossil fuel energy production facilities derived from the European Pollutant Release and Transfer Register (E-PRTR). E-PRTR cover all HELCOM Contracting Parties except Russia. Attribute specification and units: See E-PRTR code lists at https://www.eionet.europa.eu/schemas/eprtr/listOfValues In the HELCOM data review process, some facility locations appeared to be spatially slightly misplaced, adding up to uncertainty of data products derived from this dataset.

  • This dataset consists of information and status of the main pollution sources within the Baltic Sea catchment area (the Pollution Hot Spots). The HELCOM pollution Hot Spots were idenitified in 1992 by the HELCOM Joint Comprehensive Action Programme (more information is available on www.helcom.fi). The current status of active and cleaned hot spots is available https://helcom.fi/action-areas/industrial-municipal-releases/helcom-hot-spots/.
