AGSO Survey 137: Deep Crustal Seismic Data from Otway Basin, 1994-1995

A deep crustal seismic data acquisition proposal for the offshore Otway Basin in southeastern Australia. The AGSO Survey 137 project aimed to acquire approximately 4000 km of data between early December 1994 and late January 1995 to determine the basin's deep architecture and extensional processes. The survey was conducted by the Australian Ocean Data Network using tuned airgun arrays and differential GPS navigation.

Use Cases

• Model deep crustal architecture based on seismic reflection data down to 8-12 seconds.
• Characterize extensional processes in the Southern Rift System based on the survey's principal goals.
• Integrate seismic and aeromagnetic datasets to enhance basin understanding as described in the proposal.
• Test concepts from aeromagnetic data interpretation using the newly acquired seismic lines.

Strengths

• Survey designed to acquire approximately 4000 km of deep crustal seismic data.
• Parameters include a 4800 m streamer, 49 litre airgun source, and differential GPS navigation, which reportedly yielded high-quality data in prior surveys.
• Project had defined goals to determine crustal architecture and characterize linkages between geological features.

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.
