Lord Howe Rise Continental Ribbon Formation from Multi-Channel Seismic Data

Multi-channel seismic reflection and bathymetry data collected in 2016 to study the formation of the Lord Howe Rise continental ribbon during the Late Cretaceous rifting of eastern Gondwana. The processed data includes a regional east-west profile approximately 900 km long at 27.2°S, from the Tasman Basin to the Lord Howe Rise. This dataset was presented at the 2017 IAG-IASPEI conference and is hosted by the Australian Ocean Data Network.

Use Cases

• Modeling Late Cretaceous rifting processes based on described rift basins and faulting.
• Analyzing sedimentary basin evolution based on described syn-rift and post-rift sequences.
• Interpreting seismic stratigraphy based on described unconformities and basin stratigraphy.
• Comparing tectonic structures between the Tasman Basin, Dampier Ridge, and Lord Howe Rise based on described contrasts.

Strengths

• Includes a regional seismic profile approximately 900 km long.
• Describes rift basins with depths up to 3 km and sedimentary thickness up to ~3.5 km.
• Data is based on a dedicated 2016 marine geophysical survey.

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.
