1961 Marine Seismic Survey of the Carnarvon Basin, Western Australia

A reconnaissance marine reflection seismic survey was conducted in 1961 by Seismograph Service Limited for West Australian Petroleum Pty Limited. The survey covered 753 miles of traverse in the Exmouth Gulf and along the west coast of Western Australia. Its purpose was to obtain information on regional geology and map the extension of known structures in the Carnarvon Basin.

Use Cases

• Mapping subsurface geological structures based on seismic reflection data.
• Analyzing pre-Cretaceous fault trends and anticlinal axes in the Exmouth Gulf region.
• Correlating offshore seismic data with onshore geological features like the Cape Range Anticline.
• Studying the synclinal character of Cretaceous and Tertiary sediments in the survey area.

Strengths

• Survey details are precisely documented, including the total of 753 miles of traverse shot.
• Specific temporal coverage is provided, from 15th July to 20th August, 1961.
• The survey's purpose and geological findings are described in detail, including identified anticlines and fault trends.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data format specifics are unknown, which may limit suitability assessment.
• Data may reflect temporal and methodological bias inherent to 1961 seismic survey techniques.
