The Utö Atmospheric and Marine Research Station of Finnish Meteorological Institute is located on Utö Island (59º 46'50N, 21º 22'23E) at the outer edge of the Archipelago Sea. The Finnish Meteorological Institute started meteorological observations on the island in 1881, and atmospheric trace gas and aerosol measurements as member of the EMEP-network in 1980. The marine temperature and salinity record at Utö Deep dates back to 1900, being one of the longest in the whole Baltic Sea. Utö is also a member of the HELCOM marine monitoring network.

Recently, the measurement station became a founding member of the European ICOS network. The station is one of the Finnish Meteorological Institute's main observing. Currently, the marine component is developed in co-operation with Finnish Environment institute.
