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 ~900 km long east-west seismic profile and grids covering two rift basins, used to study the Late Cretaceous formation of the Lord Howe Rise continental ribbon. This work was presented at the 2017 IAG-IASPEI conference.

Use Cases

• Modeling crustal extension and rifting based on seismic reflection images of rift basins.
• Analyzing sedimentary basin stratigraphy based on described unconformities and syn-rift/post-rift sequences.
• Interpreting tectonic history based on features like transform faulting and the sharp boundary of the Tasman Basin.

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.
• Processed data includes both pre-stack depth-migrated and pre-stack time-migrated seismic images.

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 offshore region.
