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?

Our initial idea for the SEABASED project was to tackle the challenges related to internal nutrient loading in the Baltic Sea. We aimed at creating a project that in the end would provide, also some practical solutions for cutting down the eutrophication of the sea. However, when preparing the project, we found out that actually very little coherent information exists about the so call sea-based measures, and a bunch of novel and innovative ideas around them. Based on discussions with a number of stakeholders, presenting very different viewpoints and perspective, we have given our best shot to identify the most potential ideas to pilot and to learn more. What this will amount to, we now believe, is building up a fruitful dialogue between a number of stakeholders over the coming 30 months and, hopefully, finding sustainable solutions for helping the sea.

I was around six or seven years old and attended the summer swimming school, a common thing to do for kids here in the Åland Islands. This year it was held at Kaldersfjärden bay in Jomala municipality. We played, learned how to swim and dive, and jumped into the water from the floating raft.

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
