High Resolution Bathymetry Grids for Lord Howe Island Region

Four new bathymetry grids integrate seabed and topographic data for Lord Howe Island, located 450km off the coast of New South Wales. The Australian Ocean Data Network produced this data to understand seabed morphology and habitats on the island's shallow shelf. Data collection involved integrating multiple datasets, with results last updated in June 2026.

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 seabed properties as biodiversity surrogates based on the detailed bathymetry models.

Strengths

• Includes four distinct bathymetry data grids.
• Integrates bathymetry with the island's topography for coastal analysis.
• Covers the shallow shelf surrounding Lord Howe Island, with depths from 20 to 120 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified as the last update is projected for 2026.
