S2 Pit and Strain Grid Measurements of Ice Movement on Law Dome, 1959-1960

S2 Pit and Strain Grid Measurements, Law Dome 1959-1960 is a dataset documenting ice deformation from a snow pit and surface grid experiment conducted in the late 1950s. The Australian Antarctic Division (AU_AADC) archived the original hard copy, and the dataset was last updated in 1960. It contains regular measurements of peg and pole positions to record subsurface and surface ice distortion over time.

Use Cases

• Modeling ice deformation rates based on repeated peg displacement measurements.
• Analyzing surface ice movement patterns based on the tracked grid of poles.
• Calibrating ice flow models for Law Dome using historical strain data.
• Studying temporal changes in subsurface ice structure from the snow pit experiment.

Strengths

• Provides direct physical measurements of ice deformation from a controlled experiment.
• Covers a specific time period (1959-1960) for longitudinal analysis.
• Includes both subsurface (pit) and surface (grid) measurement methodologies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 1960-12-31 23:59:59.999000; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
