| contents | This data set comprises radiogenic neodymium (Nd) isotope signatures of past deep water masses and detrital matter in the Early Cretaceous (Barremian-Albian) South Atlantic Ocean and Southern Ocean, recorded at Deep Sea Drilling Project (DSDP) Sites 249, 327, 361, and 511 and Ocean Drilling Project (ODP) Site 693. Deep water Nd isotope compositions were leached from authigenic ferromanganese coatings of bulk sediment particles. Detrital Nd isotope signatures were obtained from residues of the sediment leaching procedures after dissolution via alkaline fusion. Age estimates for individual samples were calculated based on biostratigraphic and carbon isotope stratigraphic age constraints and calibrated to the time GTS2012 time scale of Gradstein et al. (2012). |
