Zhang, Zhouling; Xu, Antao; Chen, Xue-Gang; Hathorne, Edmund; Gutjahr, Marcus; Frank, Martin (2026): Conservative Behavior of Radiogenic Neodymium Isotopes in the South Pacific Interior. Earth and Planetary Science Letters, 678, https://doi.org/10.1016/j.epsl.2026.119850
This dataset contains dissolved neodymium (Nd) concentrations and radiogenic Nd isotope compositions from full water-column seawater profiles collected in the South Pacific Ocean during the GEOTRACES section GP21 (Chile to New Caledonia) aboard R/V SONNE (cruise SO289) between 23 February and 4 April 2022.
Between 10 and 40 L of seawater were collected using 10 L Niskin bottles mounted on a stainless-steel CTD rosette. Beginning at Station 18, an additional 40 L of surface seawater was collected using a trace-metal-clean tow-fish to enable Nd isotope measurements at expected low concentrations.
Samples for Nd isotope analysis were pre-concentrated onboard by coprecipitation with Fe hydroxide and later purified in the home laboratory before analysis by MC-ICP-MS (Thermo Neptune Plus). Nd concentrations were determined from 1 L acidified seawater aliquots spiked with a ¹⁵⁰Nd spike, processed via Fe-hydroxide coprecipitation and AG 50W-X8 cation exchange purification, and measured by isotope-dilution MC-ICP-MS with external reproducibility better than 0.2%. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.989250"!
