Measurements of cosmic-ray-produced nuclide concentrations in quartz from surficial glacial deposits in the Schmidt, Williams, and Thomas Hills of Antarctica's Pensacola Mountains. The dataset includes supporting field observations necessary for interpreting measurements as surface exposure ages. It was produced by SCIOPS and relates to NSF grants OPP-0838783, OPP-0838256, and OPP-0838784.
Use Cases
- Calculate surface exposure ages from cosmogenic-nuclide concentrations to date glacial retreat events.
- Correlate nuclide measurements with supporting field observations to model erosion and deposition processes.
- Analyze spatial patterns of nuclide concentrations across the Schmidt, Williams, and Thomas Hills to infer ice flow history.
Strengths
- Data covers three distinct geographic areas (Schmidt, Williams, and Thomas Hills) for spatial analysis.
- Includes both primary nuclide measurements and necessary supporting field observations for interpretation.
Limitations
- Sample size and row count are unknown, potentially limiting statistical power.
- Geographic scope is limited to a specific region of the Pensacola Mountains, Antarctica.
