North Atlantic Deep Water (NADW) represents the major water mass that drives the Atlantic Meridional Ocean Circulation (AMOC), which undergoes substantial reorganization with changing climate. In order to understand its impact on ocean circulation and climate through time, it is necessary to constrain its composition. We report Nd isotope ratios of Fe-Mn oxide encrusted foraminifera from DSDP Site 607 (41.00N 32.96W, 3427m), in the present-day core of NADW. We provide a new North Atlantic paleocirculation record covering the last 1.5 Myr.
