Indicator development for eutrophication with a focus on spring chlorophyll-a blooms and bottom oxygen 2022–2024
The eutrophication status is being regularly assessed in the Baltic Sea through several directives and conversions that require robust scientific data to adequately qualify the marine health.
Within the Helsinki Commission (HELCOM), an important part for undertake this work is the development of indicators, which address the efficiency of established measure to mitigate eutrophication in marine areas. In this context, this project will present a proposal for two main indicators, namely bottom oxygen and chlorophyll-a, that describe the response of the ecosystem to eutrophication in mainly the western Baltic Sea and the Gulf of Bothnia. For this purpose an improved tool to assess spatially resolved maps using both observations and modelling results is under development.
SMHI is leading this project and testing the proposed indicators with modelling data.
