The Bureau of Mineral Resources conducted a combined gravity and seismic survey in the Timor Sea/Joseph Bonaparte Gulf area in 1965. The seismic reflection sections recorded good-quality reflections to 1.6 seconds, and the survey identified a large Permian and Mesozoic sedimentary basin containing at least 10,000 feet of post-Permian sediments. The data is hosted by the Australian Ocean Data Network.
Use Cases
- Analyze sedimentary basin structure based on seismic reflection data mentioned in the description
- Evaluate marine gravity meter performance for reconnaissance work based on gravity anomaly trends
- Investigate the relationship between gravity anomalies and basement relief based on the survey findings
- Study the offshore extension of the Bonaparte Gulf Basin based on the identified basin extent
Strengths
- Seismic reflection sections recorded good-quality reflections to 1.6 seconds
- Survey identified a sedimentary basin containing at least 10,000 feet of post-Permian sediments
- Gravity meter and seismic equipment were operated simultaneously at boat speeds of 8 to 9 miles per hour
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 temporal bias inherent to a 1965 survey
