High Resolution Bathymetry Grids for Lord Howe Island Region

Four new bathymetry grids integrate seabed depth data with the topography of Lord Howe Island, a volcanic island 450km off the coast of New South Wales. Geoscience Australia Data created these models to identify seabed habitats and relict reef structures on the island's shallow carbonate shelf. The data are also intended for modelling tsunami interactions with the island's shelf and coast.

Use Cases

• Map seabed habitats and relict reef structures based on detailed bathymetric morphology.
• Model physical seabed processes acting on a mid-ocean carbonate shelf.
• Assess biodiversity surrogates by correlating physical seabed properties with biological patterns.
• Simulate tsunami wave interaction with the shelf and coast around Lord Howe Island.

Strengths

• Includes four distinct bathymetry grids, some integrating island topography.
• Covers the Lord Howe Island region, including its fringing coral reef and surrounding shelf.
• Report details methodology for data collection, quality control, and gridding.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and ZIP formats, which may require extraction and conversion for analysis.
