Capel and Faust Basins Geophysical Survey Data from Offshore Frontier

Between December 2006 and January 2007, Geoscience Australia acquired approximately 6000 km of 2D seismic data in the Capel and Faust basins. In late 2007, the RV Tangaroa conducted a marine reconnaissance survey collecting gravity, magnetics, multibeam sonar, and sub-bottom profiler data alongside seafloor samples. These datasets from the Australian Ocean Data Network are designed to assess petroleum prospectivity and inform marine planning.

Use Cases

• Mapping basin structure and depocentre boundaries based on gravity and magnetic coverage.
• Identifying potential petroleum seepage sites based on seafloor sampling and camera footage.
• Analyzing rift basin architecture and tectonostratigraphic history based on integrated seismic and geological datasets.
• Documenting marine biodiversity and habitats based on biological samples from the sea floor.

Strengths

• Approximately 6000 km of industry-standard 2D seismic data acquired.
• Survey identified depocentres up to 150 km in length and 40 km in width with up to 7 km of sediment fill.
• Multimodal data includes seismic, gravity, magnetics, sonar, sub-bottom profiler, and physical samples.

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, focusing on a specific offshore frontier region.
