Capel and Faust Basins Geophysical Survey Data from the 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 completed a marine reconnaissance survey, acquiring gravity, magnetics, multibeam sonar, and sub-bottom profiler data, along with seafloor samples. These datasets are designed to define the region's petroleum prospectivity and inform marine planning.

Use Cases

• Modeling basin architecture and tectonostratigraphic history based on interpreted seismic phases and sediment fill.
• Delineating depocentre boundaries based on gravity and magnetic coverage.
• Identifying potential petroleum seepage sites based on seafloor sampling and sub-bottom profiler data.
• Documenting marine biodiversity and habitats based on collected biological samples and camera footage.

Strengths

• Approximately 6000 km of industry-standard 2D seismic data acquired with an 8 km solid streamer.
• Survey identified depocentres up to 150 km in length and 40 km in width with up to 7 km of sediment fill.
• Multimodal data integration includes seismic, gravity, magnetics, sonar, 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 the specific offshore frontier region surveyed.
