This dataset contains integrated eutrophication status assessment 2011-2016, visualized for nutrient levels (C1_ER). The assessment is done on HELCOM Assessment Unit level 4: HELCOM Subbasins with coastal WFD water type or water bodies.

The HEAT 3.0 has been applied for open sea assessment units using HELCOM core indicators and for coastal areas using national WFD indicators.

For more information about the methodology, see State of the Baltic Sea report and HELCOM Eutrophication assessment manual.
