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

A 1961 reconnaissance marine reflection seismic survey conducted by Seismograph Service Limited for West Australian Petroleum Pty Limited. The survey covered 753 miles of traverse in Exmouth Gulf and coastal waters from Frazer Island to Bernier Island, Western Australia, from July 15 to August 20, 1961. Data was recorded on magnetic tapes and processed into variable-area record sections to map regional geology and fault structures.

Use Cases

• Mapping subsurface anticlinal and synclinal structures based on seismic reflection data.
• Analyzing pre-Cretaceous to post-Palaeozoic fault trends mentioned in the survey results.
• Correlating offshore seismic data with known onshore structures like the Cape Range Anticline.
• Studying the regional geology of the North-West Cape region for resource assessment.

Strengths

• Survey details are precisely documented, including the 753 miles of traverse and specific dates from July 15 to August 20, 1961.
• The description provides specific geological findings, such as the synclinal character of Exmouth Gulf and identified anticlines.
• The operational methodology is described, including the use of Lorac radio navigation and sextant positioning.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data format is PDF/HTML, which may require extraction for computational analysis.
