Abstract 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...
