Lord Howe Rise Seismic Data for Continental Ribbon Study, 2016

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 seismic refraction profile, ~600 km of 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 composition based on wide-angle seismic refraction and Moho reflection data.
• Imaging rift-fill sedimentary deposits and acoustic basement across basins using multi-channel seismic reflection profiles.
• Planning future IODP drilling sites by analyzing high-resolution 2D seismic data from seven candidate locations.
• Investigating the driving forces of continental ribbon detachment by integrating gravity and magnetic data with seismic interpretations.

Strengths

• Includes a 680 km long east-west seismic profile with data from ~100 ocean-bottom seismometers.
• Contains ~600 km of high-resolution 2D seismic reflection data targeting specific IODP drilling sites.
• Multimodal data collection includes multibeam bathymetry, gravity, and magnetic measurements alongside seismic data.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
