Exmouth Gulf Marine Seismic Survey Data from 1961

A 1961 reconnaissance marine reflection seismic survey covered Exmouth Gulf and coastal Western Australia from Frazer Island to Bernier Island. West Australian Petroleum Pty Limited conducted the two-boat operation, recording shots on magnetic tapes processed into variable area record sections. The survey identified synclinal Cretaceous and Tertiary sediments, pre-Cretaceous fault trends, and structural leads around the Salt Marsh.

Use Cases

• Mapping subsurface geological horizons based on the described Horizon 'A' and Horizon 'B'
• Analyzing pre-Cretaceous fault trends and structural axes mentioned in the survey findings
• Studying the synclinal character of Cretaceous and Tertiary sediments in Exmouth Gulf
• Correlating offshore seismic data with onshore geological maps referenced in the description

Strengths

• Survey details are specifically documented, including the use of a Lorac radio navigational system and sextant positioning
• Multiple derived maps are listed, including on specific horizons, time intervals, and water depth
• Structural interpretations are provided, such as the location of the pre-Cretaceous axis of the Cape Range Anticline

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 metadata update was 2026-05-14 05:00:24.455257
