Australian Ocean Data Network hosts a dataset of beryllium isotope measurements from Prydz Bay, Antarctica. The data includes samples from open marine, sub-ice shelf, and subglacial depositional environments. It was published in Earth and Planetary Science Letters in 2019.
Use Cases
- Tracing sediment source and transport pathways based on beryllium isotope concentrations.
- Discriminating between open marine and sub-ice shelf sediment deposits using HCl-extractable 10Be/9Be ratios.
- Reconstructing sub-ice shelf circulation strength in modern and paleo-ice sheet margins.
- Analyzing the advection of 10Be-rich open marine sediments into ice shelf cavities.
Strengths
- Data is from Prydz Bay, one of Antarctica's largest ice drainage systems.
- Measurements cover a range of depositional environments: open marine, sub-ice shelf, and subglacial.
- 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.
- Description metadata is limited; actual data quality requires manual inspection after download.
