Ocean stations measure pCO2 sea surface temperature, salinity and related variables from ocean surface waters and the near-surface atmosphere. The goal is to quantify the exchange of CO2 between the atmosphere and the ocean and to assess its variability.
ICOS Sweden operates two Ocean stations: Östergarnsholm and Tavastland
