Lord Howe Rise Seismic Reflection Data from 2016 Marine Survey

Multi-channel seismic reflection and bathymetry data from a 2016 marine survey constrains the Late Cretaceous rifting of eastern Gondwana. The processed data includes a regional ~900 km long east-west profile and grids covering two rift basins on the Lord Howe Rise. These results were presented at the 2017 IAG-IASPEI conference.

Use Cases

• Modeling crustal extension and rifting processes based on interpreted syn-rift and post-rift sequences.
• Analyzing sedimentary basin evolution based on described basin depths up to 3.5 km and stratigraphic unconformities.
• Comparing tectonic structures between the Tasman Basin, Dampier Ridge, and Lord Howe Rise based on seismic reflection interpretations.
• Investigating transform faulting history based on evidence of buried basins in the Tasman Basin.

Strengths

• Includes a long, regional seismic profile spanning approximately 900 km.
• Describes specific geological features like rift basins up to 3 km deep and a sedimentary basin ~3.5 km thick.
• Data is from a focused 2016 marine geophysical survey and was presented at a peer-reviewed conference.

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 the specific survey line at 27.2°S.
