High-Resolution Bathymetry Grids for Lord Howe Island Region

Lord Howe Island, 450km off the coast of New South Wales, is the focus of this bathymetric dataset. The data includes four new bathymetry grids, some integrated with island topography, created by Geoscience Australia. The report describes the methodology for data collection, quality control, and gridding.

Use Cases

• Identify relict reef structures and seabed habitats based on detailed bathymetric morphology.
• Model tsunami interaction with the island shelf and coast based on integrated bathymetry and topography grids.
• Study physical seabed processes and biodiversity surrogates on a mid-ocean carbonate shelf.

Strengths

• Includes four distinct bathymetry grids, with some integrating island topography.
• Covers the shallow shelf (20-120m depth) surrounding Lord Howe Island.
• Report provides detailed methodology covering 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.
