Physical-properties data from the West Antarctic Ice Sheet Divide deep ice core. The dataset includes depths of crusts and annual layers, ice density measurements, and bubble number-density counts. It was produced by AMD_USAPDC as part of a five-year collaborative project.
Use Cases
- Analyze annual layer depths to reconstruct a high-resolution chronology of ice accumulation.
- Use ice density measurements to study compaction processes and ice sheet dynamics.
- Correlate bubble number-density counts with atmospheric conditions and climate periods.
- Combine crust depth data with other core measurements to investigate ice sheet stratigraphy.
Strengths
- Data collected from a planned deep ice core in a critical Antarctic divide region.
- Includes multiple physical property measurements: layer depths, density, and bubble counts.
- Project funded for a five-year period, indicating sustained data collection efforts.
Limitations
- Specific row counts, column details, and file formats are unknown.
- Data completeness relies on a follow-on grant, suggesting potential gaps.
- Geographic coverage is limited to the single WAIS Divide location.
Provenance
- Source
- AMD_USAPDC via NASA EarthData.
- Collection Method
- Data gathered from visual observation of the ice core, density determined by flotation in isooctane, and image analysis for bubble counts.
- Geography
- West Antarctic Ice Sheet Divide region.
