Interpretation of Nd isotopes (143Nd/144Nd, represented as εNd) as a geochemical tracer for ocean circulation in the North Atlantic requires knowledge of endmember compositions of potential source waters. During early interglacials, glacial terminations, and Dansgaard-Oeschger cycles (rapid warming...
