About the website

The Saaristomeri.utu.fi (Saaristomeri means Archipelago Sea in Finnish) website is administered by the Archipelago Research Institute, University of Turku. Here, we offer e.g. online data on sea water quality at the Archipelago Sea, and live video of osprey nest on Seili island. The site is meant to serve everyone interested in nature and knowledge backed by research. The services are produced in collaboration with the Turku University of Applied Sciences and other stakeholders. Please visit each page for further information.

The renewed website was adopted in October 2017. We are still updating some of the details on our website, so stay tuned for new content on our site as things progress.


The Archipelago Research Institute is part of the Biodiversity Unit of the University of Turku, Finland. Its research station is located on the island of Seili (60°14’N, 21°57’E), in the middle region of the Archipelago Sea (northern Baltic Sea) about 7 km away from the city of Nauvo. The Institute has been operating on the island since 1964. We also have an office in Turku, in the university campus area.

The Institute participates in multidisciplinary research of the Baltic Sea, with a special focus on the Archipelago Sea. Additionally, we conduct long-term environmental monitoring and offer a number of research and teaching services and support to researchers, teachers, and students. Our own research chiefly comprises of projects studying the biological and geological condition of the Archipelago Sea. Most of the research in Seili is done in cooperation with other research groups within and outside the University of Turku. For more information, please visit our website.

The Archipelago Research Institute is part of the Finnish marine research infrastructure consortium FINMARI, coordinated by SYKE marine research centre.
