Proxy-based studies have linked the pre-industrial atmospheric pCO 2 rise of ∼20 ppmv in the mid- to late Holocene to an inferred increase in the Southern Ocean overturning and associated biogeochemical changes. However, the history of polar ocean overturning and ventilation through the Holocene rem...
