Marine Seismic Survey of Capricorn and Northern Tasman Basins

2900 km of marine multi-channel seismic reflection data were acquired during a 1989 research cruise by the Bureau of Mineral Resources. The survey investigated the structure, stratigraphy, and petroleum resource potential of offshore basins along southeast Queensland. It was the first such survey in the region since 1974 and included ties to the Aquarius-1 and Capricorn-1A wells.

Use Cases

• Model basin evolution by interpreting syn-rift and post-rift sediment sequences from seismic reflection profiles.
• Assess petroleum potential by correlating seismic stratigraphy with data from the Aquarius-1 and Capricorn-1A wells.
• Analyze tectonic structure using integrated seismic, sonobuoy refraction, gravity, and magnetic data.
• Map sediment thickness and distribution by interpreting approximately 1.5 seconds two-way travel time of post-rift marine sediments.

Strengths

• Substantial 2900 km of seismic reflection data provides regional coverage.
• Multimodal data collection includes seismic, sonobuoy refraction, gravity, magnetic, and bathymetric measurements.
• Survey provides first modern (1989) multi-channel seismic data in the region since 1974.

Limitations

• Data is from a single 1989 survey, limiting temporal analysis and modern comparisons.
• Specific sample size, row counts, and detailed file structures are unknown.
• Primary data format is HTML, which may not be directly usable for standard geophysical analysis tools.
