Carbon dioxide (CO2) is a major greenhouse gas affecting long term global climate change. According to the Global Carbon Budget 2013 (Quéré et al., 2014, Earth Syst. Sci. Data, 6, 235–263), total global carbon emissions increased from 3.9 GtC/yr in 1959 to 10.7 GtC/yr in 2012, of which approximately 43% remained in the atmosphere, 30% went to terrestrial sinks, and 27% to the oceans. A method to estimate the oceanic sink is by calculating the air-sea CO2 exchange rate of CO2. While obtaining accurate distributions of the surface ocean CO2 (SOC) is critical to minimize uncertainty for this method, it …
