High-Resolution Seismic Survey Data from the Dampier Sub-Basin

An operations report details a 1990 joint seismic acquisition program in the Dampier Sub-Basin. The survey collected 352 km of high-resolution seismic data and 530.6 km of water column geochemical data over five days. The Australian Ocean Data Network provides this record of the BMR and Woodside Petroleum project.

Use Cases

• Map subsurface geological structures using the 352 km of full stack seismic data along 17 survey lines.
• Analyze hydrocarbon seepage indicators by correlating seismic profiles with the 530.6 km of water column geochemical data.
• Assess data acquisition quality and operational parameters from the detailed timing logs (October 24-28, 1990).
• Model basin evolution by interpreting seismic line locations and data coverage in the Dampier Sub-Basin.

Strengths

• Covers 352 km of high-resolution seismic data, with 336 km as full stack data.
• Includes an additional 530.6 km of complementary water column geochemical measurements.
• Data quality was reported as good in the original operations report.

Limitations

• Primary data is likely stored on 390 legacy magnetic tapes, posing significant access and format challenges.
• The dataset is a historical snapshot from a 5-day survey in October 1990, with no temporal updates.
• Available file formats are PDF and HTML reports, not raw, machine-readable seismic data files.
