Eutrophication HOLAS 3 (Baltic sea)

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 = 0.6 to = 0.4 to = 0.2 to < 0.4 Bad: = 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.C1from_HEAT_" = Confidence for nutrient effect "Confidence.C2from_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
