AusAEM: 2024 Airborne Electromagnetic Survey of Northeast Queensland

Between July and October 2024, Geoscience Australia and the Geological Survey of Queensland conducted a 30,500 flight-line kilometre airborne electromagnetic and magnetic survey in Northeast Queensland. The survey used the TEMPEST AEM system and aims to support mineral exploration, groundwater studies, and geological mapping. Data includes processed AEM data, conductivity-depth estimates, and an acquisition report.

Use Cases

• Mapping subsurface geological structures based on airborne electromagnetic data.
• Identifying potential mineral exploration targets based on conductivity-depth estimates.
• Characterizing aquifer architecture and salinity for groundwater studies.
• Contributing to regional geological mapping based on integrated geophysical data.

Strengths

• Covers 30,500 flight-line kilometres, providing broad regional coverage.
• Data was collected using the TEMPEST AEM system, a specific industry-standard technology.
• Results include contractor-generated conductivity-depth estimates, adding interpretive value.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au.
