Seven CARIOCA lagrangian buoys drifted in the Subantarctic Zone, SAZ, of
the Indian and Pacific Ocean between 2001 and
2005. Measurements indicate that pCO2 in sea water is undersaturated
with respect to the atmospheric value and consequently the subantartic zone of
the Southern Ocean acts as a sink for atmospheric CO2 during all
seasons. Large observed pCO2 variability is associated with mixing
close to the subantarctic front, with biological activity and local warming.
These variabilities are higher than the seasonal cycle in the studied areas.
