Lord Howe Rise Marine Geophysical Data from 2016 RV Kairei Expedition

The Lord Howe Rise east of Australia is a 600 km wide, 1,600 km long continental ribbon in water depths up to 3,000 m. Data includes a 680 km east-west seismic profile, ~600 km of high-resolution 2D seismic data, and multibeam bathymetry, gravity, and magnetic data acquired in March–May 2016. The dataset was collected by JAMSTEC and Geoscience Australia and presented at a 2016 scientific meeting.

Use Cases

• Model crustal structure based on wide-angle seismic refraction data from ~100 ocean-bottom seismometers.
• Interpret rift-fill sedimentary deposits and acoustic basement using multi-channel seismic reflection profiles.
• Map seafloor topography and geological features using multibeam bathymetry, gravity, and magnetic data.
• Investigate the nature of basement (oceanic vs. continental crust) using combined OBS and MCS interpretations.

Strengths

• Includes a 680 km long seismic profile with data recorded at offsets up to 250 km.
• Covers multiple geological features including the Dampier Ridge, Middleton, Capel, and Faust basins.
• Combines multiple geophysical data types: seismic, bathymetry, gravity, and magnetics.

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.
