1970s data contains raw orientation measurements from multiple ice core boreholes on Law Dome, Antarctica. The dataset covers specific holes including SGP, BHQ, SGF, SGB, and BHD, with measurements taken between 1974 and 1979. It was archived by the Australian Antarctic Division.
Use Cases
- Analyze temporal trends in borehole orientation by comparing measurements from 1974, 1977, and 1979 for sites like SGF.
- Model ice flow or structural integrity using orientation data from specific boreholes such as SGP or BHD.
- Correlate borehole orientation measurements with other glaciological datasets using site identifiers like BHQ or SGB.
- Assess measurement consistency by examining re-measurement data documented for several boreholes.
Strengths
- Covers a defined 6-year time range from 1974 to 1979.
- Includes data from multiple distinct borehole sites (SGP, BHQ, SGF, SGB, BHD).
- Contains re-measurement data, allowing for consistency checks.
Limitations
- Data is temporally stale, with the last update recorded in 1979.
- Sample size and specific row/column counts are unknown.
- Geographic coverage is limited to the Law Dome region of Antarctica.
