Capel and Faust Basins Geophysical Survey Data

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

Use Cases

• Map depocentre boundaries and sediment thickness using gravity and magnetic coverage data.
• Identify fault-related seafloor structures and slumps from multibeam sonar imagery.
• Analyze seismic reflection profiles to define syn-rift and post-rift stratigraphic packages.
• Correlate basin architecture with the Capricorn or Taranaki basins using interpreted seismic sequences.
• Assess substrate composition and potential fluid escape sites from seafloor sampling and camera footage.

Strengths

• Approximately 6000 km of industry-standard 2D seismic data provides substantial subsurface coverage.
• Multibeam sonar, gravity, and magnetic datasets offer multi-modal geophysical constraints for basin delineation.
• Survey identified depocentres up to 150 km in length with sediment fill up to 7 km thick.

Limitations

• Specific row counts, file sizes, and sample data availability are not provided.
• Data is from 2006-2007 surveys, potentially lacking recent temporal updates.
• Primary file formats are HTML and PDF, which may require extraction for quantitative analysis.
