Abstract:
This dataset includes authigenic Fe-Mn oxyhydroxide derived neodymium (Nd) isotope data of the North Atlantic IODP site U1313 (Leg 306) from the last glacial (25 - 93 ka). The authigenic sediment phase was extracted by weekly reductive leaching. The isotope ratios are normalized to 146Nd/144Nd = 0.7219 and were analyzed on a Neptune Plus MC-ICP-MS at GEOMAR, Kiel, Germany. Aim of this study is the reconstruction of the Nd isotopic end member of northern-sourced water over the investigated timespan in order to facilitate reconstructions of the geometry of the Atlantic meridional overturning circulation.
