Multi-Isotopic Data for Sinking Particle Provenance in the Ulleung Basin

1-year time-series sediment trap data from the Ulleung Basin in the East Sea (Japan Sea). The dataset includes sinking particle fluxes and organic (radiocarbon) and inorganic (detrital neodymium) isotopic compositions from depths of 300 m, 1000 m, and 2000 m. Authored by Sun-A Lee and last updated in May 2026, it aims to constrain lateral particle advection and sediment provenance.

Use Cases

• Tracing sediment provenance based on distinct detrital neodymium (εNd) isotopic signatures of Korean and Japanese bedrocks.
• Analyzing seasonal variations in particle transport mechanisms using isotopic data from different water depths.
• Investigating the role of lateral transport and local sediment resuspension in supplying pre-aged organic carbon.
• Calibrating oceanographic models of particle sinking trajectories with multi-isotopic constraints.

Strengths

• Data covers a 1-year monitoring period from a long-term oceanographic station.
• Includes multi-isotopic measurements (radiocarbon and detrital neodymium) from three distinct water depths.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• The authors note the detrital neodymium dataset is preliminary due to limited temporal coverage.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
