Lord Howe Rise Marine Geophysical Data from 2016 RV Kairei Expedition

The Lord Howe Rise east of Australia is the subject of marine geophysical data collected in March–May 2016 by JAMSTEC and 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. Preliminary results from these 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 reflection data.
• Mapping sedimentary basin geometry and rift-fill deposits using multi-channel seismic reflection profiles.
• Investigating the driving forces of continental breakup using combined gravity, magnetic, and bathymetry data.
• Supporting site selection for scientific ocean drilling based on high-resolution 2D seismic data.

Strengths

• Data includes a 680 km long east-west seismic profile with ~100 ocean-bottom seismometers.
• Multibeam bathymetry, gravity, and magnetic data provide complementary geophysical constraints.
• Acquired in collaboration with a national geological survey (Geoscience Australia).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update is dated 2026-05-14.
