    The secret life of stickleback

    When you ask people to name Baltic fish species, they usually list perch, pike, roach, cod, salmon and so on. Only a few can name stickleback. Many people around the Baltic Sea have never even heard about stickleback, although chances are that they have seen it in shallow nearshore waters, since it is one of the commonly sighted fishes. In this blog post we dive in to hear about the secret life of stickleback, with Ulf Bergström, the marine ecologist from the Swedish University of Agricultural Sciences (SLU).

    Nordkalk donates limestone to the SEABASED-project

    Nordkalk donates limestone to the SEABASED-project for piloting a measure that could bind eutrophying phosphorus permanently into the sediments of the seabed. In the project, three pilots at selected areas with activated limestone application to phosphorus containing bottom sediments will be implemented in chosen pilot sites in coastal bays in Sweden (Östergötland and Stockholm) and Finland (Archipelago Sea). The crushed limestone will be pre-treated by burning at facilities of Cementa in Gotland and then transported to the pilot sites and spread over the seabed to bind phosphorus into the sediment.

    Pike factories reduce the adverse effects of eutrophication

    As 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.

    Sweet results after a salty summer

    In 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.

    A field excursion to the cement factory in Slite, Gotland

    When in Gotland, it is hard not to talk about limestone and the local Cementa factory. The factory was originally built 100 years ago in 1919 and now employs around 230 in Slite. The SEABASED project team and steering group visited the factory to learn more not only about the making of Cementa’s products but also about the sorbent, that is used in our pilot, which is treated in this factory. This sorbent is produced from marl and is used to bind phosphorus to the sediment in pilot sites in Sweden and Finland.

    A 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.

    How to find sites for piloting sediment removal

    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.

    Dialogue is everything

    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.

    Kaldersfjärden—childhood memories lost in 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.
