Lord Howe Rise Seismic and Geophysical Survey Data from 2016

The Lord Howe Rise, east of Australia, is the focus of marine geophysical data 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 survey 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 bathymetric data.
• Supporting site selection for scientific ocean drilling (IODP) by identifying basement and sedimentary targets.

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 across seven potential drilling sites.
• Integrates multiple geophysical data types: seismic, multibeam bathymetry, gravity, and magnetics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; last metadata update was 2026-06-05.
