Beryllium Isotope Measurements from Prydz Bay, Antarctica, for Sediment Tracing

A 2019 study published in Earth and Planetary Science Letters presents beryllium isotope measurements from sediment samples in Prydz Bay, Antarctica. The data, sourced via the Australian Ocean Data Network, was collected to test Be isotopes as tracers of sediment source and transport pathways in glacio-marine environments. It includes samples from open marine, sub-ice shelf, and subglacial depositional settings.

Use Cases

• Modeling sub-ice shelf circulation patterns based on 10Be concentrations mentioned in the description
• Discriminating between open marine and sub-ice shelf sediment deposits using HCl-extractable 10Be/9Be ratios
• Tracing sediment provenance and transport pathways in Antarctic ice drainage systems
• Calibrating Be isotopes as environmental tracers for modern and paleo-ice sheet margins

Strengths

• Data is derived from a peer-reviewed publication in Earth and Planetary Science Letters (Volume 505, 2019)
• Samples cover a range of depositional environments including open marine, sub-ice shelf, and subglacial settings
• Focus on Prydz Bay, one of Antarctica's largest ice drainage systems

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
