Three field seasons of glacial geological observations from nunataks in western Queen Maud Land, Antarctica. The data includes striae measurements, grain-size analyses, and results from geochemical, cosmogenic isotope, and radiocarbon analyses, including samples from snow petrel stomach oil deposits. The data was collected by SCIOPS during the 1989/90, 1993/94, and 1997/98 austral seasons.
Use Cases
- Reconstruct past ice flow directions by analyzing striae measurements from nunatak surfaces.
- Estimate surface exposure ages and erosion rates using cosmogenic isotope analysis results.
- Determine sediment source and transport history through grain-size and geochemical analysis results.
- Establish a chronology for glacial deposits using radiocarbon dating results from snow petrel stomach oil.
Strengths
- Data collected over three distinct field seasons spanning nearly a decade.
- Multiple analytical methods applied, including geochemical, grain-size, and multiple dating techniques (cosmogenic, radiocarbon).
- Spatial coverage includes specific nunatak groups in Vestfjella and Heimefrontfjella.
Limitations
- Sample size and row count are unknown, limiting statistical assessment.
- Data is temporally stale, with the last update recorded in March 1998.
- Geographic scope is limited to specific nunataks in western Queen Maud Land.
