Be isotope measurements from open marine, sub-ice shelf, and subglacial depositional environments throughout Prydz Bay, Antarctica. The dataset likely contains 10Be and 9Be concentrations and ratios, used to trace sediment source and sub-ice shelf circulation patterns. The data was collected for a study published in Earth and Planetary Science Letters in 2019.
Use Cases
- Tracing sediment source and transport pathways based on Be isotope signatures.
- Analyzing sub-ice shelf circulation strength based on 10Be concentrations.
- Discriminating between open marine and sub-ice shelf depositional environments based on HCl-extractable 10Be/9Be ratios.
- Modeling modern and paleo-ice sheet margin dynamics based on isotope tracer data.
Strengths
- Data covers multiple Antarctic depositional environments: open marine, sub-ice shelf, and subglacial.
- Analysis demonstrates a method for discriminating environmental settings using HCl-extractable 10Be/9Be ratios.
- Dataset is associated with a peer-reviewed publication in Earth and Planetary Science Letters (Volume 505, 2019).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific study area of Prydz Bay.
