Antarctic Gravity Measurements from 1981 Spring Traverse

1981 gravity readings were collected during a spring traverse across Law Dome and Wilkes Land. The Australian Antarctic Division gathered these measurements, with many locations recorded twice during the outward and return trips. Physical copies of the original documents are archived.

Use Cases

• Analyzing temporal variation in gravity readings by comparing 'trip out' and 'trip back' measurements at the same location.
• Mapping subsurface density anomalies across Law Dome and Wilkes Land using the gravity measurement values.
• Correlating gravity data points with specific traverse locations to create geospatial models of the Antarctic region.
• Studying instrument performance and measurement consistency by examining repeated readings from the same survey points.

Strengths

• Data includes repeated measurements at the same locations, providing a basis for assessing temporal stability.
• Coverage spans two distinct Antarctic regions: Law Dome and Wilkes Land.

Limitations

• The exact number of measurement points, rows, and columns is unknown.
• Data is from a single survey in 1981, offering no longitudinal or modern comparison.
• Physical storage of documents suggests digitization and format details are unclear.
