This dataset represents the integrated assessment of hazardous substances in the Baltic Sea in 2016-2021. This dataset displays the result of the assessment in HELCOM Assessment unit Level 3 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and offshore areas).

This dataset contains the integrated status assessment for seals (grey seals, harbour seals and ringed seals), harbour porpoise and waterbirds (surface-feeding birds, pelagic-feeding birds, benthic-feeding birds, wading birds, and grazing birds) with bycatch for the HELCOM Third Holistic Assessment of the Ecosystem Health of the Baltic Sea (HOLAS 3). 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 assessment results for pelagic habitats for the HELCOM Third Holistic Assessment of the Ecosystem Health of the Baltic Sea (HOLAS 3) based on integrating following indicators: Zooplankton mean size and total stock, Seasonal succession of dominating phytoplankton groups, Cyanobacterial bloom index, Diatom-dinoflagellate index. 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 datasets were created using the BEAT tool. https://github.com/helcomsecretariat/BEAT German coastal areas were assessed based on WFD indicators.

This dataset contains the integrated eutrophication status assessment 2016-2021 for the HELCOM Third Holistic Assessment of the Ecosystem Health of the Baltic Sea (HOLAS 3). The assessment is done using the HELCOM Eutrophication Assessment Tool: HEAT by combining assessment unit-specific results from various indicators by three MSFD criteria groups (C1: Nutrient levels, C2: Direct effect, C3: Indirect effect). The assessment is done on HELCOM Assessment Unit level 4: HELCOM Subbasins with coastal WFD water type or water bodies.  The HEAT has been applied for open sea assessment units using HELCOM core indicators and for coastal areas using national WFD indicators. The confidence values have been extracted from HEAT and weighed manually by contracting parties for more accurate estimations for the confidence of the EQRS values presented.  The intervals used to classify the Status are the following: Status class (based on EQRS) High: >= 0.8 to < 1.0 Good: >= 0.6 to < 0.8 Moderate: >= 0.4 to < 0.6 Poor: >= 0.2 to < 0.4 Bad: < 0.2 Confidence class (based on confidence %) High: >= 75 Moderate: >= 50 to < 75 Low: < 50 Attribute specifications: "HELCOM_ID" = Code of the HELCOM scale 4 assessment unit "country": country in which the HELCOM assessment unit is located or a mention to an open sea area "level_2" = Name of the HELCOM assessment unit in scale 2 "Name" = Name of the HELCOM assessment unit in scale 4b "Open_sea" = Name of the HELCOM assessment unit in the open sea "F2_Name" = Name of the HELCOM assessment unit "ER" = Overall Eutrophication ratio "ER_1" = Eutrophication ratio for Nutrients "ER_2" = Eutrophication ratio for Direct effects "ER_3" = Eutrophication ratio for Indirect effects "EQR" = Overall Ecological Quality Ratio for "EQR_1" = Ecological Quality Ratio for Nutrients "EQR_2" = Ecological Quality Ratio for Direct effect "EQR_3" = Ecological Quality Ratio for Indirect effects "EQRS" = Overall Ecological Quality Ratio scaled "EQRS_1" = Ecological Quality Ratio scaled for Nutrients "EQRS_2" = Ecological Quality Ratio scaled for Direct effect "EQRS_3" = Ecological Quality Ratio scaled for Indirect effects "EQRS_Class" = Overall effect "EQRS_1_Class" = Nutrient effect "EQRS_2_Class" = Direct effect "EQRS_3_Class" = Indirect effect "Confidence.Overall_confidence" = Overall confidence "Confidence.C1__from_HEAT_" = Confidence for nutrient effect "Confidence.C2__from_HEAT_" = Confidence for direct effect "Confidence.C3__from_HEAT_" = Confidence for indirect effect "Confidence.C_Class" = Confidence class for overall confidence "Confidence.C_1_class" = Confidence class for confidence for nutrient effect "Confidence.C_2_class" = Confidence class for confidence for direct effect "Confidence.C_3_class" = Confidence class for confidence for indirect effect

The indicator evaluates the status of the soft-bottom macrofauna community above the permanent halocline in the open sea areas of the Baltic Sea. Quantitative thresholds are used to classify the core indicators status in Achieve, Fail or Not assessed. The current assessment result shows good status in most of the evaluated assessment units. The indicator is not used in coastal areas which are assessed by national methods or in areas below the halocline which are assessed using the Oxygen debt indicator. The indicator takes into account the relative proportion of sensitive and tolerant species, as well as species richness and abundance. This dataset displays the result of the indicator in HELCOM Assessment Scale 3 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and off-shore areas), so that the indicator is only applicable in the open sea assessment units. "HELCOM_ID" = HELCOM assessment unit scale 3 ID "country" = Country "level_2" = Name of scale 2 HELCOM assessment unit "level_3" = Name of scale 3 HELCOM assessment unit "coastal" = Code of scale 3 HELCOM assessment unit "open_sea" = Name of the open sea area "Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”) "Status value" = Value of the indicator "BQI normal" Biological Quality Ratio

This dataset contains core indicator data developed under the HELCOM Third Holistic Assessment of the Ecosystem Health of the Baltic Sea (HOLAS 3).
