1961 Marine Seismic Survey Data for Carnarvon Basin

A 1961 reconnaissance marine reflection seismic survey shot 753 miles of traverse in the Carnarvon Basin, Western Australia. Conducted by Seismograph Service Limited for West Australian Petroleum Pty Limited, the survey aimed to map regional geology and fault structures in the Exmouth Gulf and coastal waters.

Use Cases

• Map Cretaceous and Tertiary synclinal structures in Exmouth Gulf using seismic reflection data.
• Trace pre-Cretaceous fault trends and anticlinal axes, such as the Cape Range Anticline extension.
• Correlate offshore seismic data with known on-land structures like the Rough Range Anticline.
• Establish structural ties between the Rough Range-Cape Range area and the complex Salt Marsh region.

Strengths

• 753 miles of seismic traverse data provides substantial spatial coverage.
• Survey details include specific navigational methods (Lorac system, sextant) and recording on magnetic tape.

Limitations

• Data is from a single survey in 1961, offering no temporal evolution or modern comparisons.
• Original raw data formats (magnetic tapes) and specific columnar data are not described, limiting direct analysis.
