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.
What does internal load mean?

May 8, 2019A visit to Västervik ‒ where it all started
In the end of March, the Government of Åland and the County Administrative Board of Östergötland headed for Västervik, Sweden, or more specifically, Gamleby. Besides being the second largest urban area in Västervik Municipality, Gamleby is also the location for an exciting project. Annica Brink, a project coordinator in the Government of Åland, writes how brackish waters have been used to irrigate agricultural fields in Sweden.

Have you ever wondered how pilot sites are chosen in field experiments? Irma Puttonen, project planner from the Centre for Economic Development, Transport and the Environment for Southwest Finland, reveals her secrets on how the sites in the sediment removal pilot study have been chosen.

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.Go to pilots
