Timor Sea Seismic and Gravity Survey, 1965

A 1965 marine survey by the Bureau of Mineral Resources tested a spark discharge seismic source and surface gravity meter simultaneously. Seismic reflections of good quality were recorded to 1.6 seconds while the vessel traveled at 8 to 9 miles per hour. The survey revealed a large offshore sedimentary basin containing at least 10,000 feet of post-Permian sediments.

Use Cases

• Modeling the extent and depth of the Permian and Mesozoic Bonaparte Gulf Basin based on seismic reflection data.
• Analyzing the correlation between gravity anomalies and subsurface basin structure mentioned in the description.
• Evaluating the historical performance of spark array seismic sources and marine gravity meters for reconnaissance work.

Strengths

• Simultaneous collection of gravity and seismic reflection data, as described.
• Good-quality seismic reflections recorded to a depth of 1.6 seconds.
• Survey identified a basin with over 10,000 feet of post-Permian sediment thickness.

Limitations

• Data is from 1965; acquisition technology and processing methods are historical.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
