Southern Prince Charles Mountains in Antarctica were sampled during the PCMEGA expedition in the 2002/03 summer. Approximately 200 sediment, 50 surface salt, and 100 cosmogenic exposure age samples were collected, with field analysis including clast rounding, lithology, weathering features, and Schmidt hammer tests. The data, including images and a spreadsheet, were produced by the PCMEGA project and ASAC project 1071.
Use Cases
- Date glacial highstands based on cosmogenic exposure age samples.
- Analyze sediment grain size and elemental composition based on the less than 2 mm fraction.
- Study geomorphic agents like frost shattering and glacial polish based on documented weathering features.
- Model glacial history based on quantified clast rounding and lithology.
- Assess weathering degree using the Moriwaki et al. scheme documented in the description.
Strengths
- Approximately 200 sediment samples provide a substantial collection.
- Field analysis includes quantified metrics like clast rounding and Schmidt hammer tests at ~30 sites.
- Multimodal data includes images and a spreadsheet.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2003-01-23 23:59:59.999000; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
