Dissolved neodymium concentrations and neodymium isotope compositions for deep water (≥1500 m) samples of R/V SONNE cruise SO245-UltraPac in the South Pacific
This dataset includes seawater neodymium (Nd) concentrations and Nd isotope signatures (expressed as ε-Nd) obtained from a zonal deep-water (1500 – 5321 m water depth) transect across the oligotrophic South Pacific gyre (transect between Antofagasta, Chile, and Wellington, New Zealand). The samples...
