SummaryDuring the Quaternary, changes in atmospheric CO2 concentrations led to major climate changes such as glacial/interglacial cycles. Our studies indicate that the combination of a decrease in ocean overturning through an increased stratification in the Antarctic zone of the Southern Ocean and increased organic carbon export through iron fertilization in the sub-Antarctic zone of the Southern Ocean can explain much of the G/IG's atmospheric CO2 changes during the last 800,000 years and the entire Quaternary.
