Australian Geophysical Survey Lines for Magnetic, Radiometric, and Gravity Data

Individual airborne and ground survey lines of geophysical data from Australia and its marine area. The collection includes Total Magnetic Intensity, Gamma-ray spectrometry (potassium, thorium, uranium), elevation, and Bouguer Gravity measurements. These datasets have been used to create both survey-scale and national grids for geophysical analysis.

Use Cases

• Model subsurface geology and mineral deposits based on Total Magnetic Intensity and Bouguer Gravity data.
• Map natural radiation levels and geological composition based on Gamma-ray spectrometry (K, Th, U) measurements.
• Create regional and national geophysical grids based on the aggregated survey line data.
• Correlate airborne geophysical signatures with ground-based gravity surveys for integrated analysis.

Strengths

• Contains multiple geophysical data types: Total Magnetic Intensity, Gamma-ray spectrometry, elevation, and Bouguer Gravity.
• Data sourced from publicly available government- and company-acquired surveys across Australia and its marine area.
• Hosted at the National Computational Infrastructure (NCI), suggesting institutional support for large-scale data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
