Lord Howe Rise Marine Geophysical Data from 2016 Seismic Survey

March–May 2016 marine geophysical data acquired 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 data, and multibeam bathymetry, gravity, and magnetic data. It was presented at the 2016 Seismological Society of Japan Fall Meeting.

Use Cases

• Modeling crustal structure based on wide-angle seismic refraction data from ~100 ocean-bottom seismometers.
• Interpreting rift-fill sedimentary deposits and acoustic basement based on multi-channel seismic reflection profiles.
• Investigating driving forces for continental ribbon detachment based on combined gravity and magnetic data.
• Planning deep-sea drilling sites based on high-resolution 2D seismic data at seven proposed IODP locations.

Strengths

• Includes a 680 km long east-west seismic profile with conjoint wide-angle refraction and multi-channel reflection data.
• Covers a 600 km wide, 1,600 km long continental ribbon in water depths up to 3,000 m.
• Seismic data recorded clear arrivals from the basement and mantle at offsets up to 250 km.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF and HTML formats, which may require extraction for computational analysis.
