High Resolution Bathymetry Grids for Lord Howe Island Region

Four new bathymetry grids integrate seabed depth data with the island's topography for the Lord Howe Island region. The data were created by the Australian Ocean Data Network to support marine habitat and physical process studies. The report describes the methodology for data collection, quality control, and gridding.

Use Cases

• Identify seabed habitats and relict reef structures based on detailed bathymetric morphology.
• Model tsunami wave interaction with the coastal shelf based on integrated bathymetry and topography grids.
• Study physical seabed processes acting on a mid-ocean carbonate shelf based on high-resolution depth data.
• Assess biodiversity surrogates by correlating seabed physical properties with ecological patterns.

Strengths

• Includes four distinct bathymetry grids, some integrating island topography.
• Covers a defined region around Lord Howe Island, approximately 450km off the New South Wales coast.
• Describes a detailed methodology for data collection, quality control, and gridding.

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; last metadata update is listed as 2026-06-23.
