Antarctic Sediment Luminescence Dates from Bunger Hills

Bunger Hills in Antarctica contains luminescence dating results for marine and fluvial sediments. Data includes instrumental neutron activation analysis (INAA) subsamples for dosimetry calculation and optically stimulated luminescence (OSL) dates. The project was conducted under ASAC Project 2237, with analyses performed at Royal Holloway, University of London, and metadata was last updated in 1999.

Use Cases

• Validate the OSL dating technique's reliability in Antarctic conditions using sample-specific INAA dosimetry data.
• Assess the hypothesis of incomplete glaciation at Bunger Hills during the last glacial maximum by analyzing OSL sample ages.
• Correlate sediment deposition events in marine versus fluvial environments using dated sample locations and types.

Strengths

• First OSL dates produced from Antarctica, providing a foundational dataset.
• Includes complementary INAA analysis for dosimetry calculation on each OSL sample.

Limitations

• Specific row count, column names, and sample data are unavailable for review.
• Data is from 1999, representing early-stage application of the technique.
