Project 121.30: Seismic Survey of the Southern Lord Howe Rise Region

A marine geophysical dataset from Survey 114, which acquired 3,191 km of multichannel seismic data in the southern Lord Howe Rise and West Norfolk Ridge region. The project was conducted by Geoscience Australia in late 1992 to investigate the geological framework and assist with defining Australia's continental shelf boundaries. The data was collected using 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 the investigation of major structural features.
• Reconstructing tectonic evolution based on data on thinned continental lithosphere and ocean basins.
• Supporting legal continental shelf definition based on acquired geophysical data.

Strengths

• Contains 3,191 km of acquired seismic data with 30-fold coverage.
• Report describes data quality as 'very good' with noise levels within specifications during key lines.
• Project had clear objectives focused on structure, stratigraphy, and resource assessment.

Limitations

• Data files are in PDF and HTML formats, not a structured, machine-readable data format.
• Column-level documentation is absent; field semantics must be inferred after download.
