Lord Howe Island Seabed Bathymetry Grids with Integrated Topography

Lord Howe Island, approximately 450km off the coast of New South Wales, is the focus of this bathymetric dataset. Geoscience Australia created four new bathymetry grids, including models that integrate seabed data with the island's topography, to understand seabed processes and habitats. The data was last updated on March 25, 2026.

Use Cases

• Identify relict reef structures and seabed habitats based on detailed bathymetric models.
• Model tsunami interaction with the island's shelf and coast based on high-resolution seabed data.
• Analyze physical seabed properties as biodiversity surrogates on a mid-ocean carbonate shelf.
• Study seabed morphology and the physical processes acting on it based on integrated bathymetry and topography grids.

Strengths

• Includes four new bathymetry grids, with some integrating island topography.
• Covers the shallow shelf (20-120m depth) surrounding Lord Howe Island.
• Report describes methodology, data collection, quality control, and gridding processes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
