Lord Howe Rise Seismic Data for Continental Ribbon Study

Marine geophysical data from the Lord Howe Rise east of Australia, acquired in March–May 2016. The dataset includes a 680 km seismic refraction profile, ~600 km of 2D seismic reflection data, and multibeam bathymetry, gravity, and magnetic data. Preliminary results from this data were presented at the 2016 Seismological Society of Japan Fall Meeting.

Use Cases

• Modeling crustal thickness and composition based on wide-angle seismic refraction and Moho reflections.
• Mapping sedimentary basin geometry and rift-fill deposits using multi-channel seismic reflection profiles.
• Investigating the driving forces of continental ribbon detachment using combined gravity, magnetic, and bathymetry data.

Strengths

• Includes a 680 km long east-west seismic profile with data from ~100 ocean-bottom seismometers.
• Covers multiple geological features including the Dampier Ridge, Middleton, Capel and Faust basins, and the Lord Howe Platform.
• Data acquisition was a collaborative effort between JAMSTEC and Geoscience Australia.

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.
