Description
Between 25 October 2008 and 19 January 2009, Geoscience Australia conducted marine survey GA2476 using the RV Sonne. The survey mapped 229,000 km² of seabed, collected 25,000 line-km of seismic data, and sampled 62 stations across four frontier basins off Western Australia. This report provides a preliminary analysis of geological, geophysical, oceanographic, and biological data to assess petroleum prospectivity and environmental significance.
Use Cases
Assess petroleum prospectivity based on geological and geophysical data from frontier sedimentary basins.
Model seabed morphology based on multi-beam sonar mapping covering 229,000 km².
Analyze marine environmental significance based on biological samples and oceanographic data.
Support resource management decisions for future offshore acreage release based on integrated basin analysis.
Strengths
Survey covers a large geographic area of 229,000 km² with multi-beam sonar mapping.
Integrated data collection includes 25,000 line-km each of seismic, gravity, and magnetic data.
Sampling includes 62 stations using diverse equipment like CTD profilers, boxcores, and rock dredges.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Data freshness should be verified; the report is from 2009, though metadata was updated in 2026.
