PCMEGA: Airborne Gravity and Magnetic Survey of the Prince Charles Mountains, Antarctica

December 2002 to January 2003 data collected by the Prince Charles Mountains Expedition of Germany and Australia (PCMEGA). The dataset contains airborne gravity and magnetometer measurements from a survey covering the Prince Charles Mountains in Antarctica, flown by Fugro Airborne Surveys. It includes 29,844 line kilometres of data with precise geodetic and instrument specifications.

Use Cases

• Modeling subsurface geological structures based on gravity anomaly data.
• Mapping magnetic anomalies to infer crustal composition and tectonic history.
• Integrating geophysical data for regional geological interpretation of the Prince Charles Mountains.
• Calibrating or validating satellite-derived gravity and magnetic models with high-resolution airborne data.

Strengths

• High-resolution instrument specifications: gravity data at 0.1 mGal resolution and magnetic data at 0.001 nanotesla resolution.
• Extensive spatial coverage: 29,844 line kilometres flown with defined survey boundaries.
• Precise geodetic and operational metadata, including WGS84 datum, survey dates, and aircraft specifications.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2003-01-31 23:59:59.999000; freshness should be verified.
• Row count and file formats are unknown, which may limit suitability assessment.
