A set of digital bathymetry, gravity, and magnetic grids for Australia's continental margin, produced by the Australian Geological Survey Organisation in cooperation with Desmond Fitzgerald and Associates and the Australian Hydrographic Service. The grids have a resolution of 250 to 1000 meters and represent an upgrade of marine ship-track data, integrated with satellite and high-resolution onshore sources using levelling techniques to correct errors.
Use Cases
- Geological modeling based on integrated gravity and magnetic anomaly data.
- Seafloor mapping and feature identification based on bathymetry data.
- Resource exploration targeting based on merged ship-track and satellite potential field data.
- Geophysical research based on levelled and corrected marine survey data.
Strengths
- Grid resolution is specified as 250 to 1000 meters.
- Data integrates multiple sources, including ship-track, satellite, and onshore data.
- Levelling techniques were applied to correct crossover and other errors.
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.
