Eutrophication Status

Category Management
Sub-category Environmental conditions

Description

Eutrophication (from Greek eutrophos, "well-nourished"), or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients that induce excessive growth of plants and algae. This process may result in oxygen depletion of the water body. Eutrophication is almost always induced by the discharge of nitrate or phosphate-containing detergents, fertilizers, or sewage into an aquatic system.

MSP Challenge

Eutrophication Status is a static data layer for reference only.

Original Title

Integrated eutrophication status assessment 2017.

Description

"The dataset contains integrated eutrophication status assessment 2011-2015. The assessment is done using the HEAT tool 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 3.0 tool has been applied for open sea subasins and in coastal areas using national WFD indicators. In case of Denmark, the WFD results were used directly, displaying different classification as obtained from HEAT.

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

NOTE: The dataset was corrected in 5 December 2017 regarding C3 values for Åland Sea, Bothnian Sea and Bothnian Bay (Oxygen debt was excluded from C3 calculation for those areas)."
