Crustal Transects of the Great Australian Bight: Seismic Survey Proposal

A 4087 km deep-seismic survey proposal for the central Great Australian Bight and margin south of Western Australia. The data aims to support tectonic evolution studies, an Ocean Drilling Program proposal, and Australia's Law of the Sea continental shelf claim. The proposal was submitted by the Australian Ocean Data Network.

Use Cases

• Model tectonic evolution based on deep crustal structure transects.
• Identify the continent-ocean boundary based on seismic and magnetic data.
• Analyze the structural origin of the Diamantina Zone based on its relationship to seafloor spreading.
• Support petroleum exploration acreage release programs based on margin event history.
• Provide framework data for Ocean Drilling Program proposals based on seismic refraction data.

Strengths

• Proposes acquisition of 4087 km of deep-seismic data.
• Specifies a 16-second record length for seismic data.
• Integrates legacy seismic refraction data from Lamont-Doherty Geological Observatory (1976).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
