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.


  • Baltic Sea ecosystems (brackish water ecosystems characterised by vast archipelagos with high habitat complexity)


Ecosystem access

  • Motor boats (15-90 hp) for sampling in coastal waters
  • Two cars for towing boat trailers
  • Near-shore diving facility


Experimental facilities and technology platforms

  • Sampling equipment (water samplers, plankton nets, sediment corers, grabs, dredges, trawls, seines, gill nets and handheld probes)
  • Controlled indoor and outdoor experimental studies with filtered flow-through seawater (c. 5.5 PSU)
  • Possibilities for field experiments in diverse habitats
  • Permission to conduct fishing with several methods and is certified to conduct experiment with fish


Associated services

  • Long-term data for temperature, salinity, pH, nutrients, chlorophyll and benthic macrofauna

HBS is open for visiting scientists all year round, with most activity occurring during the open-water season, and has accommodation for up to 50 people.
