Exmouth Gulf Marine Seismic Survey Maps from Western Australia, 1961

West Australian Petroleum Pty Limited conducted a reconnaissance marine reflection seismic survey in Exmouth Gulf and coastal waters from Frazer Island to Bernier Island in 1961. The survey was a two-boat operation using Lorac radio navigation and sextant positioning, with results processed into magnetic tape record sections. The dataset includes constructed maps of horizons within Cretaceous and pre-Cretaceous structures, water depth, and time intervals.

Use Cases

• Mapping Cretaceous and Tertiary sediment synclinal character based on survey results.
• Tracking pre-Cretaceous fault trends beneath the Gulf based on the described structural leads.
• Analyzing the structural alignment of islands northeast of the Cape Range based on identified trends.
• Correlating geological structures between the Rough Range-Cape Range area and the Salt Marsh complex based on the Cuvier marine survey tie.

Strengths

• Survey employed two distinct positioning systems (Lorac radio navigation and sextant measurements) for different areas.
• Results were processed into multiple specific map types covering horizons, structure, intervals, and water depth.
• Survey provided a structural tie between two geographically distinct complex areas south of Point Maud.

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 temporal bias inherent to a single survey conducted in 1961.
