Lord Howe Rise Geophysical Data and Petroleum Prospects

Lord Howe Rise, a submarine feature in the Tasman Sea 600-1200 km off Australia's east coast, is described by preliminary geophysical results from the Australian Ocean Data Network. The dataset likely contains information on sediment-filled basins, seismic profiles, and petroleum prospectivity assessments. It was last updated on 2026-05-05.

Use Cases

• Mapping submarine basin dimensions based on described widths of 20-40 km and sediment thicknesses up to 4000 m.
• Analyzing petroleum trap structures based on descriptions of boundary faults, internal basin structures, and interpreted reefs.
• Assessing potential petroleum source rocks based on descriptions of shallow marine silts and clays and palaeogeographical reconstructions.
• Modeling pre-Tasman Basin rift structures based on descriptions of horst and graben zones and conjectural relationships.

Strengths

• Description provides specific geographic dimensions: the feature is about 2000 km long and 300 km wide.
• Description includes concrete sediment thickness measurements: some basins contain up to 4000 m of sediment.
• Description references specific data sources like seismic profiles and DSDP Site 207.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a specific region.
