Lord Howe Rise Marine Seismic Survey 2016 Bathymetry Grids

Lord Howe Rise, a submerged plateau within Australian marine jurisdiction, is the focus of this bathymetry dataset. Geoscience Australia and JAMSTEC collected multibeam data covering 62,360 km² during a 2016 seismic survey to assess potential deep-sea drilling sites. Eight bathymetry grids with 50 to 80-meter resolution were produced from the shipborne 12 KHz sonar system.

Use Cases

• Site selection for deep-sea stratigraphic drilling based on seabed topography.
• Geomorphological analysis of the Lord Howe Rise plateau based on bathymetric grids.
• Integration with seismic data for subsurface geological modeling based on the survey's purpose.
• Baseline mapping for marine jurisdiction and environmental management based on the defined area.

Strengths

• Covers a large, defined area of 62,360 km².
• Provides high-resolution bathymetry grids at 50 to 80 meters.
• Data was collected by authoritative institutions (Geoscience Australia and JAMSTEC) for a specific scientific proposal.

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.
