1961 Marine Seismic Survey Data for the Carnarvon Basin, Western Australia

A reconnaissance marine reflection seismic survey was conducted in 1961 by Seismograph Service Limited for West Australian Petroleum Pty Limited. The survey covered 753 miles of traverse in the Carnarvon Basin, including Exmouth Gulf and coastal waters from Frazer Island to Bernier Island. Data was processed into variable-area record sections to map regional geology and fault structures.

Use Cases

• Mapping regional subsurface geology based on seismic reflection data.
• Analyzing pre-Cretaceous fault trends and anticlinal structures mentioned in the survey results.
• Correlating offshore seismic data with known onshore structures like the Cape Range Anticline.
• Studying the synclinal character of Cretaceous and Tertiary sediments in Exmouth Gulf.

Strengths

• Survey details are precisely documented, including a total of 753 miles of traverse shot.
• Specific temporal coverage from 15th July to 20th August, 1961.
• Clear geographic scope defined as the Carnarvon Basin, Exmouth Gulf, and coastal waters from Frazer Island to Bernier Island.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a 1961 survey; freshness should be verified for modern applications.
