Measurements in the Atmosphere and Sea:
Atmospheric measurements on the site includes 3D wind speed with sonic anemometers, eddy covariance measurements of CO2, H20 and heat fluxes. There is a gradient system for CO2 and H20 at the site and propeller anemometers and thermocouples in the 30 m tower. Relative humidity, atmospheric pressure, global radiation and precipitation is also measured on the site. During different time periods other parameters have also been observed such as methane, oxygen and clouds.
Water-side measurements are taken using several different sensors semi-continously during active deployment periods. These measurements include sea surface temperature and profile measurements of temperature and conductivity (measured as proxy for salinity) at depth ranging from about 0.5 to 20 m. Also measured are carbon dioxide (pCO2), oxygen, pH, Chlorphyll, Turbidity and fDOM as well as wave parameters in collaboration with Finnish Meteorological Institute (FMI). Discrete manual water side measurements and sampling include Phosphorous (TP, PO4), Nitrogen (TNm, NH4, NO3+NO2) and Silica (DSi).
