Exmouth Gulf Marine Seismic Survey Data from 1961

A 1961 reconnaissance marine reflection seismic survey was conducted in Exmouth Gulf and coastal waters from Frazer Island to Bernier Island, Western Australia. The survey was a two-boat operation by West Australian Petroleum Pty Limited, producing maps of geological horizons, structure, and water depth. Processed magnetic tape recordings were used to construct maps for horizons within the Cretaceous and pre-Cretaceous periods.

Use Cases

• Mapping subsurface geological structure based on interpreted seismic horizons A and B.
• Analyzing pre-Cretaceous fault trends and anticline axes mentioned in the survey results.
• Studying the synclinal character of Cretaceous and Tertiary sediments in Exmouth Gulf.
• Correlating marine seismic data with on-land surveys to establish structural continuity.

Strengths

• Survey employed two distinct navigational systems (Lorac radio and sextant) for positioning.
• Data was processed into variable area record sections from magnetic tape recordings.
• Maps were constructed for multiple geological horizons and time intervals.

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.
