Many palaeoceanographic studies have sought to use the Pa-231/Th-230 ratio as a proxy for deep ocean circulation rates in the North Atlantic. As of yet, however, no study has fully assessed the concentration of, or controls on, Th-230 and Pa-231 in waters immediately following ventilation at the sta...
