About the Archipelago Institute

The Archipelago Research Institute runs a marine field station on the island of Seili, about one hour from the city of Turku in Finland. The island lies in the central Archipelago Sea in the northern Baltic Sea.With its thousands of islands, shallow waters and natural salinity gradient, the Archipelago Sea offers exceptional conditions for studying coastal ecosystems and environmental change.

Research at the station focuses on the Baltic Sea, especially the Archipelago Sea. The work is supported by long-term environmental observations and marine monitoring, which provide valuable time-series data on ecological change in this region. The island location gives direct access to coastal and offshore field sites throughout the archipelago.

We support research and teaching by providing laboratories, field equipment, boats and practical assistance. The station is open year-round to Finnish and international researchers, students and courses.

The Institute takes part in several Finnish and European research infrastructure networks, including RESTAT, FINMARI, AnaEE, FinLTSER and EMBRC-ERIC. Research carried out at Seili contributes to understanding and sustainable management of the Baltic Sea.

The Archipelago Research Institute is part of the Department of Biodiversity Sciences at the University of Turku.
