Infrastructure and services

The Archipelago Research Institute offers resources for research and education, dedicated especially in advancing our understanding related to the Archipelago Sea and the Baltic Sea. The research station is located on the island of Seili, serving as a hub for multidisciplinary research, field courses, summer schools, seminars and congresses, and independent travellers.

Our facilities and services for researcher and teaching

Our research infrastructure provides a wide range of resources to support research and educated, related, for example, on marine and coastal ecosystems, wild fish stocks and experimental ecology. Our facilities are located at the heart of the Seili island, encompassing the historical main building and adjacent buildings. These facilities are designed to cater to a wide range of research and educational needs. The station’s infrastructure is available for researchers at other universities and also companies. The Archipelago Research Institute is part of the Finnish Marine Infrastructure Community (FINMARI) and Finnish Research Stations network.

  • Facilities: We provide access to workrooms, laboratories, motorboats, field and laboratory equipment, and in- and outdoor experimental facilities with flow-through seawater. Long-term data is also available, for example, on weather, seawater quality (via e.g. automated water quality monitoring platform), and plankton community composition. The station also maintains an environmental biobank, containing various biological samples from the Archipelago Sea, the oldest samples being from the 1960s.
  • Research Support: Our research station is equipped to support researchers and research groups, interested in working with various topics related to the archipelago and the Baltic Sea. We provide access to wide array of research equipment and services, please contact us for more information!
  • Field Courses and School Groups: We offer facilities and equipment to enhance the learning experience for both university courses and school groups visiting the island.
  • Travel Services: Travel services, such as accommodation and restaurant services, are provided by an independent travel company Visit Seili. Please refer to their webpage for more information.
