High-Resolution Bathymetry Grids for Lord Howe Island Shelf

The Australian Ocean Data Network created detailed bathymetry grids for the Lord Howe Island region. The dataset includes four grids integrating seabed and island topography to model physical processes and habitats. The report, last updated in 2026, describes the methodology for data collection, quality control, and gridding.

Use Cases

• Identify relict reef structures and seabed habitats based on detailed bathymetric morphology.
• Model tsunami wave interaction with the island shelf and coast based on integrated bathymetry and topography grids.
• Analyze physical seabed properties as biodiversity surrogates on a mid-ocean carbonate shelf.
• Study major seabed processes and morphology on a shallow (20-120m) volcanic island shelf.

Strengths

• Includes four new bathymetry grids, some integrating island topography.
• Focuses on a specific, ecologically significant region: Lord Howe Island, 450km off the NSW coast.
• Methodology for data collection, integration, and quality control is described in an accompanying report.

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.
• Data may reflect geographic bias inherent to the specific island region.
