The Seabased Project
The most large-scale problem of the Baltic Sea is eutrophication. While we have 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) assesses measures that improve the status of marine area by reducing the internal load of the sea. The project pilots 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 2019-2020.

Alongside the pilot activities, SEABASED has a mission to develop a concept of aquatic compensation in coastal waters with focus on nutrient offsetting. The objective is to examine different options and needs for new regulations for legislation and to find functional and sustainable solutions, e.g., to be utilized in ecosystem-based compensations in the future, for which Åland will act as “a test laboratory”. The concept will be applied and tested in practice with pilot activities to reduce nutrients from the marine environment and to restore the coastal pilot areas into better conditions. A model for a Water Improvement Fund will also be described with the effort of taking aquatic compensation from theory into practice.

December 17, 2020SAVE THE DATE: International SEABASED webinar 26.1.2021Could the spreading of activated limestone or fishing stickleback help remove nutrients from the Baltic Sea? Do these new conservation measures have potential to save the Baltic Sea, or will they remain as experiments? In the SEABASED online event on January 26th, 2021 we will tell more about the results from SEABASED pilots that aim to reduce internal nutrient load. We will also hear keynotes and expert views from Finland and Sweden. The event will be held in English. A more detailed program will be published on the SEABASED website in early 2021. The timetable is announced according to the Finnish time zone (UTC+2).

December 3, 2020The guide to building a pike factoryThe population of pike has decreased radically in recent decades, which has created an imbalance in the coastal ecosystems in the Baltic Sea. In the SEABASED-project, we have worked to investigate if there were suitable conditions in our selected pilot areas in Östergötland to establish “pike factories”. Administrator Kenneth Winroth from the County Administrative Board of Östergötland reveals what we have learned about planning and constructing a pike factory.
