Project 121.30: Seismic Survey of Southern Lord Howe Rise and West Norfolk Ridge

Geoscience Australia Data conducted Survey 114 in 1992 to acquire approximately 3191 km of multichannel seismic data. The project aimed to investigate the geological framework and resource potential of the southern Lord Howe Rise and West Norfolk Ridge region. Data collection occurred over a 21-day period in November and December 1992.

Use Cases

• Model basin development and stratigraphy based on deep crustal seismic lines.
• Assess hydrocarbon or mineral resource potential based on structural features mentioned in the description.
• Analyze tectonic framework and crustal characteristics to understand 'ribbon continent' formation.
• Support legal continental shelf definition for Australia based on acquired geophysical data.

Strengths

• Acquired 3191 km of multichannel seismic data using a 3000 m streamer and 49 litre sleeve gun arrays.
• Data quality was reported as very good, with noise levels within specifications during calm weather.
• Survey designed with long regional lines extending from the Tasman Basin to the Norfolk Basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a specific survey in 1992; freshness should be verified for contemporary applications.
