Husö biological station (HBS) belongs to the Environmental and Marine Biology, Faculty of Science and Engineering, Åbo Akademi University. HBS established in 1959 is situated at Bergö in the central part of the Åland Islands. HBS holds long-term data bases on marine environmental change and has collaboration with the autonomous Government of the Åland Islands. HBS is base for diverse aquatic studies, but also botanical and entomological studies are conducted. HBS offers space for scientists, students and field courses and provides infrastructure for experimental aquatic ecology, laboratory analyses, marine biological sampling of coastal brackish waters as well as lakes in relative unaltered ecosystems of the Baltic Sea.The archipelago is vastly complex with high habitat diversity. HBS facilitates long-term monitoring, coastal field studies, and experimental research. The station has a long tradition of application of scientific results in management, legislation, and societal purposes in co-operation with third sector bodies. The research at HBS centres on climate change and eutrophication effects on structure and function of key marine habitats, and communities and populations of coastal ecosystems. HBS provides TA services for ASSEMBLE Plus, for which the University of Helsinki (UH) is the Finnish partner.
