| contents | This dataset presents detrital (particulate) neodymium isotope composition (143Nd/144Nd, expressed as εNd) from bulk sediments at Ocean Drilling Program (ODP) Site 162-982 on the Rockall Plateau, North Atlantic. The measurements cover selected intervals over the past approximately 230 ka. Prior to total digestion, authigenic and carbonate phases were removed to isolate the terrigenous fraction. Neodymium isotope composition were measured on a Thermo Fisher Scientific Neptune Plus multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) at the Institute of Environmental Physics, Heidelberg University. These data constrain the provenance of detrital inputs to the Rockall Plateau and help evaluate potential detrital overprinting of the co-located authigenic εNd record. |
