Crustal Transects of the Great Australian Bight: Deep-Seismic Survey Proposal

A cruise proposal outlines plans to acquire 4,087 km of deep-seismic data in the Great Australian Bight. The survey aims to support petroleum exploration, scientific drilling proposals, and Australia's continental shelf claim under UNCLOS. It was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Modeling tectonic evolution and margin formation based on deep crustal structure data.
• Supporting petroleum exploration by enhancing understanding of the margin's event history.
• Providing framework data for proposals to the Ocean Drilling Program.
• Supporting legal claims to an extended continental shelf under the UN Convention on the Law of the Sea.

Strengths

• Proposes acquisition of 4,087 km of deep-seismic data with a 16-second record length.
• Integrates legacy seismic refraction data recorded by Lamont-Doherty Geological Observatory in 1976.
• Addresses three distinct, high-value objectives: petroleum exploration, scientific drilling, and legal claims.

Limitations

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