In this study we measure the Sm, Nd and Pb isotope signatures of the clayey fraction of deglacial and Holocene sediments from 4 deep North Atlantic cores. Radiogenic isotopes are use to trace the particle provenance. Temporal changes in the relative contribution of the different source-areas bring i...
