Bathymetry Grids for Lord Howe Island with Integrated Topography

Four high-resolution bathymetry grids model the seabed around Lord Howe Island, located 450km off the coast of New South Wales. The dataset integrates bathymetry with the island's topography and was created by Geoscience Australia. The report describes data collection, quality control, and gridding methodologies.

Use Cases

• Identify relict reef structures and seabed habitats based on detailed bathymetric morphology.
• Model tsunami wave interaction with the island's shelf and coast using the bathymetry grids.
• Study physical seabed processes and their role as biodiversity surrogates on a mid-ocean carbonate shelf.

Strengths

• Includes four distinct bathymetry grids, some integrating bathymetry with island topography.
• Covers a defined region around Lord Howe Island, including its shallow (20-120m) surrounding shelf.
• 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 and data volume are unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-04-20 03:31:59.050903.
