West Antarctic Aerogeophysical Measurements from Airborne Surveys

Aerogeophysical measurements from the West Antarctic Ice Shelf were collected between 1994 and 2001. The dataset includes ice-penetrating radar, laser altimetry, magnetics, and airborne gravity data. It was provided by the Support Office for Aerogeophysical Research at the University of Texas Institute for Geophysics.

Use Cases

• Model ice sheet thickness and bedrock topography using ice-penetrating radar data.
• Analyze subglacial geological features and magnetic anomalies from the magnetics measurements.
• Measure ice surface elevation changes over time with the laser altimetry time series.
• Study gravitational fields and isostatic adjustment using the airborne gravity data integrated with GPS positioning.

Strengths

• Data collection spans 7 years from 1994 to 2001.
• Includes multiple integrated geophysical measurement types from a dedicated airborne platform.

Limitations

• Dataset is temporally stale, with the last update recorded in 2004.
• Specific sample sizes, row counts, and file formats are unknown.
• Geographic coverage is limited to the West Antarctic Ice Shelf region.
