Beryllium isotope measurements from sediment samples collected in Prydz Bay, Antarctica. The dataset includes samples from open marine, sub-ice shelf, and subglacial depositional environments, published in Earth and Planetary Science Letters in 2019. The data was sourced from Geoscience Australia via data_gov_au.
Use Cases
- Tracing sediment sources and transport pathways in glacio-marine environments based on Be isotope concentrations.
- Modeling sub-ice shelf circulation strength in modern and paleo-ice sheet margins using 10Be/9Be ratios.
- Discriminating between open marine and sub-ice shelf sediment depositional environments based on HCl-extractable isotope ratios.
Strengths
- Data is linked to a peer-reviewed publication in Earth and Planetary Science Letters (Volume 505, 2019).
- Samples cover multiple distinct depositional environments (open marine, sub-ice shelf, subglacial) within a major Antarctic ice drainage system.
- The description provides a clear scientific rationale for using Be isotopes as tracers of circulation and environment.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
