Lord Howe Island Shelf Infauna and Seabed Habitat Survey

Geoscience Australia Data collected infauna and seabed habitat data from the Lord Howe Island shelf. The dataset likely contains species counts, sediment composition, and geomorphic zone classifications from grab sampling and multibeam sonar mapping. It was last updated on 2026-03-25.

Use Cases

• Predicting infaunal community structure based on geomorphic zones like drowned lagoon or outer shelf.
• Modeling species abundance and trophic structure using sediment composition and seafloor topography.
• Analyzing biogeographic dispersal patterns by comparing endemic and mainland taxa densities.
• Mapping habitat suitability for benthic species based on physical disturbance and nutrient supply factors.

Strengths

• Data integrates biological sampling with high-resolution multibeam sonar seabed mapping.
• Study design explicitly links fine-scale bio-physical surveys with broad-scale habitat mapping.
• Covers three distinct geomorphic zones: drowned lagoon, relict reef, and outer shelf.

Limitations

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