Lord Howe Rise Marine Seismic Survey 2016 Bathymetry Grids

Geoscience Australia and JAMSTEC collected bathymetry data during the KR1605 survey from 17 March to 16 May 2016. The dataset contains eight bathymetry grids covering 62,360 km2 of the Lord Howe Rise plateau at water depths of 1000-3000m. Grids were produced from shipborne 12 KHz sonar data with resolutions of 50 to 80 meters.

Use Cases

• Modeling seabed topography for geological research based on multibeam bathymetry data.
• Selecting potential drill sites for deep stratigraphic coring based on bathymetric surveys.
• Analyzing the morphology of the submerged Lord Howe Rise plateau based on high-resolution grids.
• Supporting seismic interpretation and site assessment for the International Ocean Discovery Program.

Strengths

• Covers a large, defined area of 62,360 square kilometers.
• Provides high-resolution bathymetry grids at 50 to 80 meter resolution.
• Data was collected by authoritative institutions Geoscience Australia and JAMSTEC.

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.
