Biogeochemical control of the coupled CO2-O2 system of the Baltic Sea: A review of the results of Baltic-C
Past, present, and possible future changes in the Baltic Sea acid-base and oxygen balances were studied using different numerical experiments and a catchment-sea model system in several scenarios including business as usual, medium scenario, and the Baltic Sea Action Plan. New CO2 partial pressure d...
