Cosmogenic nuclide concentrations in glacial erratics from the Marble Hills in the Ellsworth Mountains, Antarctica. The dataset includes sample locations, correction factors, and concentrations of Be-10 and Al-26 measured in quartz, with conventional exposure ages provided. The data was produced by the organization SCIOPS and sourced from NASA's Earthdata platform.
Use Cases
- Modeling West Antarctic Ice Sheet thinning by analyzing Holocene exposure ages derived from Be-10 and Al-26 concentrations.
- Investigating prolonged glacial exposure histories using high concentrations of cosmogenic nuclides Be-10 and Al-26 in samples.
- Recomputing exposure ages for sensitivity analysis using provided sample locations and correction factors.
- Correlating sample locations in the Marble Hills with regional deglaciation patterns from the Last Glacial Maximum.
Strengths
- Includes concentrations for two key cosmogenic nuclides, Be-10 and Al-26, allowing for cross-validation of exposure ages.
- Provides sufficient correction factors and data to recompute exposure ages if production rates are revised.
Limitations
- Sample size is limited, with only approximately one-third of samples having Holocene exposure ages.
- Specific row count, column details, and temporal coverage of sample collection are unknown.
