Lord Howe Rise Marine Seismic Survey 2016 Bathymetry Grids

From 17 March to 16 May 2016, bathymetry data was collected over the Lord Howe Rise plateau by Geoscience Australia and JAMSTEC. The survey covered 62,360 km² at water depths of 1000-3000m, producing eight bathymetry grids with 50 to 80m resolution. This data supports site assessment for a potential deep stratigraphic drilling project proposed to the International Ocean Discovery Program.

Use Cases

• Model seabed topography for drill site selection based on the described bathymetry grids.
• Analyze geological features of the Cretaceous Eastern Gondwana Margin based on the survey's research context.
• Integrate bathymetric data with other marine datasets for regional geological studies.
• Assess seabed conditions for future scientific expeditions based on the described site assessment purpose.

Strengths

• Covers a specific, large area of 62,360 km².
• Data resolution is specified as 50 to 80 meters.
• Produced by authoritative institutions (Geoscience Australia and JAMSTEC).
• Has a clear temporal scope (17 March to 16 May 2016).

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.
