Lord Howe Rise Seismic Data for Continental Ribbon Study

Marine geophysical data acquired in March–May 2016 onboard the JAMSTEC vessel R/V Kairei in collaboration with Geoscience Australia. The dataset includes a 680 km long east-west seismic profile, ~600 km of high-resolution 2D seismic reflection data, and multibeam bathymetry, gravity, and magnetic data. It was presented at the 2016 Seismological Society of Japan Fall Meeting.

Use Cases

• Modeling crustal thickness and basement nature based on wide-angle seismic refraction and ocean-bottom seismometer data.
• Mapping rift-fill sedimentary deposits and acoustic basement using multi-channel seismic reflection profiles.
• Investigating driving forces for continental breakup based on combined gravity, magnetic, and bathymetry data.
• Supporting site selection for scientific drilling proposals based on high-resolution 2D seismic data.

Strengths

• Includes a 680 km long east-west seismic profile with ~100 ocean-bottom seismometers.
• Contains ~600 km of high-resolution 2D seismic reflection data for seven potential drilling sites.
• Data was acquired in a targeted area (Lord Howe Rise) with water depths up to 3,000 m.

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.
