Many palaeoceanographic studies have sought to use the 231 Pa∕ 230 Th 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, 230 Th and 231 Pa in waters immediately following ventilation at the st...
