Exmouth Gulf Marine Seismic Survey Data from Western Australia, 1961

A 1961 reconnaissance marine reflection seismic survey conducted in Exmouth Gulf and along the west coast of Western Australia. The survey was a two-boat operation by West Australian Petroleum Pty Limited, using Lorac radio navigation and sextant positioning, with data recorded on magnetic tapes. It produced maps of Cretaceous horizons, pre-Cretaceous structure, water depth, and interval times, revealing synclinal character and fault trends.

Use Cases

• Mapping subsurface geological structure based on interpreted seismic horizons A and B.
• Analyzing fault trends and anticline axes in pre-Cretaceous formations mentioned in the description.
• Correlating offshore seismic data with onshore geological maps for regional studies.
• Investigating the synclinal character of Cretaceous and Tertiary sediments in the Exmouth Gulf area.

Strengths

• Survey details are explicitly documented, including the two-boat operation and navigational methods (Lorac and sextant).
• Specific mapped horizons and structures are listed, such as Horizon 'A' and 'B' and the pre-Cretaceous axis of the Cape Range Anticline.
• Provides a structural tie between the Rough Range-Cape Range area and the Salt Marsh area as noted 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 may reflect geographic and temporal bias inherent to a single 1961 survey.
