Marine Seismic Survey Data from Exmouth Gulf, Western Australia, 1961

Exmouth Gulf and coastal waters along the west coast of Western Australia from Frazer Island to Bernier Island were surveyed in 1961 by West Australian Petroleum Pty Limited. The reconnaissance marine reflection seismic survey was a two-boat operation using Lorac radio navigation and sextant positioning. Processed magnetic tape recordings were used to construct maps of geological horizons, pre-Cretaceous structure, and water depth.

Use Cases

• Mapping subsurface geological structure based on interpreted seismic horizons.
• Analyzing fault trends and anticline axes based on pre-Cretaceous structure maps.
• Studying sediment thickness and synclinal character based on time interval maps between horizons.
• Correlating onshore and offshore geological features based on the survey's tie to land seismograph data.

Strengths

• Survey covers a specific geographic area from Frazer Island to Bernier Island.
• Data includes multiple constructed maps focusing on distinct geological horizons and water depth.
• Positioning methods are documented, using Lorac radio navigation and sextant measurements.

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.
