Lord Howe Rise Marine Seismic Survey 2016 Bathymetry Grids

Bathymetry products from a 2016 seismic survey over the Lord Howe Rise, a submerged plateau in Australian waters. The survey was conducted by Geoscience Australia and JAMSTEC from March to May 2016, covering an area of 62,360 km². Eight bathymetry grids with 50 to 80-meter resolution were produced using a shipborne 12 KHz sonar system.

Use Cases

• Modeling seafloor topography for geological research based on multibeam bathymetry data.
• Selecting potential deep-sea drilling sites based on seabed structure and depth.
• Analyzing the morphology of the Lord Howe Rise plateau based on high-resolution bathymetric grids.
• Supporting marine spatial planning and habitat mapping based on detailed depth information.

Strengths

• Covers a large survey area of 62,360 square kilometers.
• Provides high-resolution bathymetry grids at 50 to 80-meter resolution.
• Data was collected by established scientific institutions (Geoscience Australia and JAMSTEC) for a specific research proposal.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is explicitly not to be used for navigational purposes, limiting its application scope.
