Short summary
Our new planktonic foraminiferal stable carbon isotopic data from the western South Atlantic show major decreases during abrupt climate change events of the last glacial. These anomalies are likely related to periods of a sluggish Atlantic meridional overturning circulation and increase (decrease) in atmospheric CO2 (stable carbon isotopic ratios). We hypothesize that strengthening of Southern Ocean deep-water ventilation and weakening of the biological pump are responsible for these decreases.
