| Various human activities, including fossil fuel combustion and forest clearing, emit about eight petagrams (or billion tons) of carbon in the form of CO2 into the atmosphere annually. The global ocean absorbs about two petagrams of CO2, and about a half of that amount is absorbed by the Southern Ocean south of 30°S, thus slowing the rapid accumulation of CO2 in the atmosphere. Partial pressure of CO2 (pCO2) is a measure of the chemical driving force for the CO2 exchange between the ocean and the atmosphere. This paper discusses its space and time distribution over the Southern Ocean. The major sink zone for atmospheric CO2 is located in a latitude belt between 30°S and 50°S, where the biological utilization of CO2 and cooling of warm subtropical waters... |
