Exmouth Gulf Marine Seismic Survey Data from 1961

A 1961 reconnaissance marine reflection seismic survey was conducted in Exmouth Gulf and along the west coast of Western Australia by West Australian Petroleum Pty Limited. The two-boat operation produced maps of geological horizons, pre-Cretaceous structure, water depth, and time intervals between key layers. The data indicated the synclinal character of the Gulf and helped trace major fault trends and the axis of the Cape Range Anticline.

Use Cases

• Modeling subsurface geological structure based on mapped horizons and fault trends.
• Analyzing the relationship between surface and subsurface features like the Cape Range Anticline.
• Correlating seismic data between different geological regions, such as between the Rough Range-Cape Range area and the Salt Marsh.
• Studying the character of Cretaceous and Tertiary sediments in a marine syncline.

Strengths

• Survey conducted with specific navigational systems (Lorac radio, sextant) for positioning.
• Original data recorded on magnetic tapes and processed into variable area record sections.
• Multiple interpretative maps were constructed for key geological horizons and structures.

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; the survey is from 1961.
