Lord Howe Rise Seismic Reflection Data from 2016 Marine Survey

The Australian Ocean Data Network provides multi-channel seismic reflection and bathymetry data from a 2016 marine geophysical survey. The dataset includes a processed pre-stack depth-migrated seismic reflection profile approximately 900 km long, covering the Tasman Basin to the Lord Howe Rise. These data were used to study the Late Cretaceous rifting of eastern Gondwana and the formation of the Lord Howe Rise continental ribbon.

Use Cases

• Modeling tectonic rifting processes based on seismic reflection images of rift basins.
• Analyzing sedimentary basin evolution based on described syn-rift and post-rift sequences.
• Studying transform faulting history based on identified buried basins in the Tasman Basin.
• Comparing rift basin characteristics based on the contrasting evolution described for two basins on the Lord Howe Rise.

Strengths

• Includes a regional seismic reflection profile approximately 900 km long.
• Data reveals rift basins with depths up to 3 km and a sedimentary basin up to 3.5 km thick.
• Contains both pre-stack depth-migrated and pre-stack time-migrated seismic reflection grids.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
