Integrated Eutrophication Status Assessment HOLAS 3

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

Statement

The dataset was created in order to update the information for the integrated assessment under HOLAS 3. Following a data call submitted to Contracting Parties in April 2021. HELCOM HOLAS III Data call covers all current regular monitoring data reporting as well as supplemental data that is required for the State of the Baltic Sea report.
