  • Data set represents the HELCOM 1x1 km Baltic Sea grid, that was originally created for the HOLAS II project (State of the Baltic Sea report 2018) and used in the Baltic Sea Impact Index and Shipping density maps produced for HELCOM Maritime Assessment. The grid is based on the European Environment agency (EEA) grid system, and its compatible with all other grid sizes. The grid covers the whole Baltic Sea water area: A grid cell is included in the data set if some part of the 1x1 km cell touches water according to the EEA coastline data set. Same method is applied to cut the grid to match the HELCOM marine area. Attribute information: HELCOM_subbasin_ID: HELCOM subbasin ID where the cell is located HELCOM_subbasin_name: HELCOM subbasin name where the cell is located

  • Dataset description: This dataset displays spatial coverage of available data on riverine inputs of hazardous substances to the Baltic Sea. The data illustrates availability and where available contains values of annual average inputs of hazardous substances (the latest assessment period) from sub-catchments and coastal areas designated for the HELCOM PLC assessment. The sub-catchments are the smallest areas for which loads of nutrients and hazardous substances are assessed. Sub-catchments are always located within borders of a single country and drain into one Baltic Sea sub-basin. Sub-catchments may correspond to either monitored or unmonitored areas. Unmonitored sub-catchments may represent either unmonitored parts of river catchments or aggregated unmonitored areas (depending on the reporting format of each Contracting Party). The data is obtained through national monitoring programmes and annually reported by Contracting Parties to the HELCOM Pollution Load Compilation (PLC-water) database as an integral part of HELCOM Pollution Load Compilation process https://nest.su.se/helcom_plc/. However, the assessment of inputs and respective data updates are performed periodically in accordance with the workplan of respective PLC-projects. The data is produced, compiled and quality assured in accordance with the HELCOM Guidelines for the annual and periodical compilation and reporting of waterborne pollution inputs to the Baltic Sea (HELCOM PLC-Water Guideline).

  • Dataset description: The dataset reflects spatial delineation of monitored and unmonitored sub-catchments used to compile data on inputs of nutrients and hazardous substances to the Baltic Sea sub-basins in the HELCOM Pollution Load Compilation. The sub-catchments are the smallest entities for which inputs of nutrients and hazardous substances to the Baltic Sea are reported. The sub-catchments are always located within borders of a single country and drain into a single Baltic Sea sub-basin. Sub-catchments may correspond to either monitored or unmonitored areas. Unmonitored sub-catchments may represent either unmonitored parts of river catchments or aggregated unmonitored areas (depending on the reporting format of each Contracting Party). Polygonal features in the dataset have attributes indicating whether a sub-catchment represents monitored or unmonitored area. A specific attribute indicates that the sub-catchment is in the upstream country of a transboundary river catchment. The data is reported to the HELCOM Map and Data Service (MADS) and quality assured by Contracting Parties to HELCOM in accordance with the HELCOM Guidelines for the annual and periodical compilation and reporting of waterborne pollution inputs to the Baltic Sea (HELCOM PLC-Water Guideline).
