Proxy-based studies have linked the pre-industrial atmospheric $$p_{{\rm{CO}}_{2}}$$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 t...
