High Resolution Bathymetry Grids for Lord Howe Island Region

Detailed seabed bathymetric data grids for the Lord Howe Island region, created to understand marine environments and physical seabed processes. The dataset includes four new grids integrating bathymetry with the island's topography, produced by the Australian Ocean Data Network. The report describing the methodology was last updated on 2026-06-17.

Use Cases

• Identify seabed habitats and relict reef structures based on high-resolution bathymetry.
• Model tsunami wave interaction with the continental shelf and coast based on detailed depth data.
• Measure how physical seabed properties act as surrogates for biodiversity patterns on a mid-ocean carbonate shelf.
• Analyze seabed morphology to understand physical processes acting on the seabed.

Strengths

• Includes four new bathymetry grids, some integrating bathymetry with island topography.
• Covers the Lord Howe Island region, which includes a volcanic island, fringing coral reef, and a surrounding shelf from 20 to 120 meters deep.
• Methodology report covers data collection, quality control, and gridding processes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Freshness should be verified as the last update timestamp is in the future (2026-06-17).
