A 2020 research dataset from the WAIS Divide ice core site in West Antarctica, produced by AMD_USAPDC. It integrates ice core analyses, borehole deformation measurements, and Electron Backscatter Diffraction (EBSD) microstructure studies. The data aims to link ice fabric evolution, impurity content, and flow dynamics to climate history.
Use Cases
- Model ice flow patterns near divides using borehole deformation time-series from Acoustic Televiewers.
- Correlate climate history signals with layered microstructure variations from EBSD fabric measurements.
- Analyze the relationship between impurity content and ice microstructure evolution with depth.
- Integrate fabric data from thin section analyses with sonic velocity and optical dust logging records.
Strengths
- Integrates multiple novel measurement techniques including EBSD and Acoustic Televiewer time-series.
- Builds upon extensive existing data from WAIS Divide borehole logging and ice core projects.
Limitations
- Specific row counts, column details, and sample sizes are not provided.
- Dataset is temporally static, representing a snapshot from research concluded around 2020.
