UTO Atmospheric and Marine Research Station

Utö is one of the main observing sites of FMI. The Island can be reached 4 times a week by free public transport and has a hotel with conference facilities. Marine observations are mainly scientistsoperated, with strong support from FMI observing services unit. Infrastructure includes the following observations: • Surface waves and temperature; currents (-23 m … -0.5 m); temperature, salinity, turbidity, chlorophyll, O2 (-5 m); Ice cover; pCO2; sea-atmosphere CO2-flux; • Temperature, salinity, O2, nutrient profiles (-80 m…0 m) during open sea period only; • A continuous water flow from the sea (possible to install new instruments utilizing ~ 5 lpm sea water/instrument) • Atmospheric CO2- and CH4-concentrations; Meteorology: wind speed and direction, temperature, PAR, diffuse and global radiation, weather camera; atmospheric trace gases; physical, chemical and optical properties of aerosol particles.
