Carbon uptake and biogeochemical change in the Southern Ocean, south of Tasmania

The carbon content of the water masses of the Southern Ocean south of Tasmania has increased over the period 1995–2011, leading to a general decrease in pH. An enhancement in the upwelling of DIC-rich deep waters is the main plausible cause of the increase in carbon in surface waters south of the Polar Front. North of the Polar Front, strong winds favor the ventilation of surface to intermediate layers, where the DIC increase is explained by the uptake of atmospheric CO2.
