Beryllium isotope measurements from sediment samples collected in Prydz Bay, Antarctica. The dataset likely contains concentrations of 10Be and 9Be isotopes from open marine, sub-ice shelf, and subglacial depositional environments. The data was produced by researchers including Duanne A. White and David Fink and published in Earth and Planetary Science Letters in 2019.
Use Cases
- Tracing sediment source and transport pathways based on Be isotope signatures.
- Discriminating between open marine and sub-ice shelf depositional environments based on HCl-extractable 10Be/9Be ratios.
- Analyzing sub-ice shelf circulation strength patterns based on 10Be concentrations.
- Reconstructing paleo-ice sheet margin conditions using Be isotope tracers.
Strengths
- Data is focused on Prydz Bay, one of Antarctica's largest ice drainage systems.
- Measurements cover a range of depositional environments including open marine, sub-ice shelf, and subglacial settings.
- The dataset is associated with a peer-reviewed publication in Earth and Planetary Science Letters.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last updated metadata is dated 2026-05-05.
