3,191 km of multichannel seismic data were acquired during a 1992 survey to investigate the geological framework of the southern Lord Howe Rise and West Norfolk Ridge region. The Australian Ocean Data Network hosts this post-cruise report detailing the project's objectives to assess resource potential and define Australia's legal continental shelf. Data acquisition used a 3,000 m streamer and 49 litre sleeve gun arrays over a 21-day period.
Use Cases
- Modeling basin development and stratigraphy based on deep crustal seismic lines.
- Assessing hydrocarbon resource potential based on major structural features within the region.
- Determining tectonic framework and crustal evolution based on data on thinned continental lithosphere.
- Supporting legal definitions of Australia's continental shelf based on acquired geophysical data.
Strengths
- 3,191 km of seismic data acquired with 30-fold coverage.
- Data quality described as 'very good' with noise levels within specifications during key lines.
- Survey specifically targeted a region relevant to a 1.65 million km2 area of Australia's legal continental shelf.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
