Proxy-based studies have linked the pre-industrial atmospheric pCO(2) rise of similar to 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 Ho...
