The export of deep water from the Arctic to the Atlantic contributes to the formation of North Atlantic Deep Water, a crucial component of global ocean circulation. Records of protactinium-231 ((231)Pa) and thorium-230 ((230)Th) in Arctic sediments can provide a measure of this export, but well-cons...
