Geophysical Survey Data for Australia's Capel and Faust Basins

The Australian Ocean Data Network hosts geophysical data from the remote Capel and Faust Basins, located 800 km east of Brisbane in 1000-3000 m water depth. The dataset includes integrated 2D seismic reflection, sonobuoy refraction, and marine potential-field data collected as part of the Australian Government's Energy Security Initiative. Interpretation suggests the presence of syn-rift and post-rift sedimentary packages, with a maximum depocentre thickness of approximately 4 seconds two-way travel time.

Use Cases

• Modeling crustal extension and basin formation based on negative residual gravity anomalies and seismic reflection data.
• Mapping fault and horizon structures in 3D using potential-field data to link isolated depocentres.
• Characterizing basement terranes and sequence boundaries through forward and inverse 3D modeling of gravity and magnetic data.
• Analyzing the distribution of volcanic and intrusive features based on reduced-to-pole positive magnetic anomalies.

Strengths

• Includes multiple integrated geophysical data types: 2D seismic reflection, sonobuoy refraction, and marine potential-field data.
• Covers a specific, remote frontier area with water depths between 1000 and 3000 meters.
• Supports 3D mapping and modeling of subsurface structures.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The 20-50 km separation between 2D seismic lines complicates linking structures, as noted in the description.
