High Resolution Bathymetry Grids for the Lord Howe Island Region

The Australian Ocean Data Network presents detailed seabed bathymetric data grids for the Lord Howe Island region. The dataset includes four new grids integrating bathymetry with island topography, created to understand seabed processes and habitats. The data are also intended for modelling tsunami interactions with the island's shelf and coast.

Use Cases

• Identify major seabed processes and habitats based on detailed bathymetry data.
• Map relict reef structures based on high-resolution seabed morphology models.
• Model tsunami interactions with the shelf and coast based on integrated bathymetry and topography grids.
• Assess physical seabed properties as biodiversity surrogates based on data from this mid-ocean carbonate shelf.

Strengths

• Includes four new bathymetry grids, some integrating bathymetry with the island's topography.
• Data collection methodology is described, covering data collection, quality control, and gridding.
• Designed for specific applications in seabed habitat identification and tsunami modelling.

Limitations

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