Carnarvon Basin Marine Seismic Survey Data from 1961

A 1961 marine seismic survey covered 753 miles of traverse in the Carnarvon Basin, Western Australia, including Exmouth Gulf and coastal waters from Frazer Island to Bernier Island. Conducted by Seismograph Service Limited for West Australian Petroleum Pty Limited, the survey aimed to map regional geology and pre-Cretaceous faulting. Results indicated synclinal structures in Exmouth Gulf and extended known anticlines like the Cape Range Anticline.

Use Cases

• Mapping subsurface geological structures based on seismic reflection data.
• Analyzing pre-Cretaceous to post-Palaeozoic fault trends in the North-West Cape region.
• Correlating onshore and offshore geological features like the Rough Range Anticline.
• Studying the synclinal character of Cretaceous and Tertiary sediments in Exmouth Gulf.

Strengths

• Survey covered a specific 753-mile traverse, providing a defined spatial scope.
• Project details are precisely documented, including dates (July 15 to August 20, 1961) and navigational methods.
• Results are tied to specific geological features like the Cape Range Anticline and Salt Marsh area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single 1961 survey; its resolution and compatibility with modern techniques are unknown.
• Row count is unknown, which may limit suitability assessment.
