Lord Howe Rise Marine Bathymetry Grids from 2016 Seismic Survey

From 17 March to 16 May 2016, Geoscience Australia and JAMSTEC collected multibeam bathymetry data covering 62,360 km² of the Lord Howe Rise plateau. The dataset contains eight bathymetry grids with 50 to 80m resolution, produced from a shipborne 12 KHz sonar system during survey KR1605. This work supports site assessment for a potential International Ocean Discovery Program drilling proposal.

Use Cases

• Modeling seafloor topography based on 50-80m resolution bathymetry grids
• Selecting deep-sea drilling sites based on seismic survey data
• Analyzing the structure of the Lord Howe Rise submerged plateau based on bathymetric coverage
• Integrating bathymetry data with other marine geological surveys for regional analysis

Strengths

• Covers a large, defined area of 62,360 km²
• Provides eight specific bathymetry grids with 50 to 80m resolution
• Data collected by authoritative institutions (Geoscience Australia and JAMSTEC) during a dedicated 2016 survey

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
