West Australian Petroleum Pty Limited commissioned a reconnaissance marine reflection seismic survey in 1961, conducted by Seismograph Service Limited. The survey covered 753 miles of traverse in the Carnarvon Basin, focusing on Exmouth Gulf and coastal waters from Frazer Island to Bernier Island. The project aimed to map regional geology and pre-Cretaceous fault trends, with results subsidized under the Petroleum Search Subsidy Act 1959.
Use Cases
- Map regional geological structures based on seismic reflection data.
- Analyze pre-Cretaceous to post-Palaeozoic faulting trends mentioned in the survey objectives.
- Correlate offshore seismic data with known onshore structures like the Cape Range Anticline.
- Study the synclinal character of Cretaceous and Tertiary sediments in Exmouth Gulf.
Strengths
- Survey covers a specific 753-mile traverse, providing a defined spatial scope.
- Detailed operational methodology is described, including navigation systems and recording on magnetic tapes.
- Project purpose and geological findings are explicitly stated in the description.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data freshness should be verified; last updated metadata is 2026-05-05.
