The Seabased Project
The most large-scale problem of the Baltic Sea is eutrophication. While we’ve been successful in cutting the nutrient load from land, nutrients that are stored in the seabed slow down the Sea’s recovery. The SEABASED Project (Seabased Measures in Baltic Sea Nutrient Management) will assess measures that improve the status of marine area by reducing the internal load of the sea. The project will pilot selected measures in the pilot areas in Finland, Åland and Sweden.
Pilots
SEABASED pilots are small-scale local activities, testing methods to alleviate the internal nutrient load in the Baltic Sea with low risks of causing any negative effects to the ecosystem. Piloted measures, that could help reduce the effects of excess nutrient load in the Baltic Sea include e.g. removing the active, oxygen-consuming surface layer of bottom sediment; recycling the nutrient-rich water from the proximity of the seabed for use in farming; and retaining phosphorus in the seabed sediment using natural, limestone-based materials, e.g. marl. Most of SEABASED pilot activities will be implemented during 2019.

February 14, 2020Pike factories reduce the adverse effects of eutrophicationAs one of the measures in the SEABASED project to help control eutrophication, a pike factory, i.e., an artificial small-scale wetland suitable as a breeding area for pike, will be created in the Linköping area in Sweden. Marine biologist Miina Mäki, the Project Manager for the SEABASED project, describes how the pike factories work and why they are important.

January 24, 2020Sweet results after a salty summerIn one of the SEABASED pilots nutrient-rich bottom waters are removed from two eutrophied semi-closed, coastal bays and the possibility of recycling nutrients by utilizing the water for irrigation on fields is tested. Annica Brink, a project coordinator from The Government of Åland, reveals the first results from two irrigated fields.
