Bathymetry Grids for Lord Howe Island with Integrated Topography

The Australian Ocean Data Network provides detailed seabed bathymetry data for the Lord Howe Island region. The dataset includes four new bathymetry grids, some of which integrate bathymetry with the island's topography. The data were created to understand seabed morphology, identify habitats and relict reef structures, and enable tsunami modelling.

Use Cases

• Identify seabed habitats and relict reef structures based on detailed bathymetric morphology.
• Model tsunami wave interaction with the island's shelf and coast based on integrated bathymetry and topography grids.
• Analyze physical seabed processes acting on a mid-ocean carbonate shelf based on high-resolution depth data.
• Assess the relationship between seabed properties and biodiversity patterns based on the described data purpose.

Strengths

• Includes four distinct bathymetry grids, with some integrating island topography.
• Covers the shallow shelf (20-120m depth) surrounding Lord Howe Island, approximately 450km off the New South Wales coast.
• Report describes 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 size are unknown, which may limit suitability assessment.
