  • This dataset represents the Integrated biodiversity status assessment for pelagic habitats. Status is shown in five categories based on the integrated assessment scores obtained in the tool. Biological Quality ratios (BQR) above 0.6 correspond to good status. The status of the pelagic habitats in the open sea was assessed using the core indicator ‘Zooplankton mean size and total stock’ in the northern part of the Baltic Sea (Gulf of Bothnia, Gulf of Finland and the Northern Baltic Proper) and the two eutrophication indicators ‘Cyanobacterial bloom index’ and ‘Chlorophyll-a’ in order to represent changes in primary producers. The indicator ‘Chlorophyll-a’, gives a general measure of the level of primary productivity, via variation in the biomass of phytoplankton, and responds strongly to eutrophication. Coastal areas were assessed by national indicators. This dataset displays the result of the integrated biodiverity status in HELCOM Assessment unit Scale 4 (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). Attribute information: "Code" = Code of scale 4 Helcom assessment unit "Descriptio" = Name of the Helcom scale 4 assessment unit "BQR" = Biological Quality Ratio "Confidence" = Confidence of the assessment "Number_of" = Number of indicators (0-5) "F__of_area" = % of area assessed "D1C6" = MSFD descriptor 1 criteria 6 "Legend" = Class text for the legend

  • This dataset represents the Integrated biodiversity status assessment for seals (grey seal, harbour seal and ringed seal). Status is shown in five categories based on the integrated assessment scores obtained in the tool. Biological quality ratios (BQR) above 0.6 correspond to good status. The status of the seals was assessed using four core indicators: population trends and abundance of seals, distribution of Baltic seals, nutritional status of seals, and reproductive status of seals. In the latter two only grey seals are considered for now. The assessment is based on the one-out-all-out approach, i.e. the species reflecting the worst status in each assessment unit. This dataset displays the result of the integrated biodiversity status in HELCOM Assessment unit Scale 2 (Division of the Baltic Sea into 17 sub-basins). Attribute information: "SB_Code" = Code of HELCOM subbasin "Name" = Name of the Helcom scale 2 assessment unit "AreaKM2" = Area of the HELCOM scale 2 assessment unit "HELCOM_ID" = HELCOM id of the HELCOM scale 2 assessment unit "BQR" = Biological Quality Ratio "Confidence" = Confidence of the assessment "Nr_of_ind" = Number of indicators "F__of_area" = % of area assessed

  • In 2010, HELCOM completed the initial assessment (HOLAS I) of the ecosystem health of the Baltic Sea – including the associated costs and benefits to the society. The assessment was based on data from 2003 to 2007. The summary report can be found at: https://helcom.fi/wp-content/uploads/2019/08/BSEP122.pdf and more information about HOLAS I at: https://helcom.fi/baltic-sea-trends/holistic-assessments/2010-initial-holistic-assessment/ All datasets for HOLAS I and associated metadata were here compiled.
