Lord Howe Island shelf data from a study integrating high-resolution multibeam sonar mapping with sediment and infauna sampling. The dataset likely contains information on species assemblages, sediment composition, and seabed topography to examine bio-physical relationships. It was published via the Australian Ocean Data Network and last updated in June 2026.
Use Cases
- Modeling infaunal community structure based on broad-scale geomorphic zones like drowned lagoon and relict reef.
- Predicting species richness and abundance using sediment composition variables such as grain size and sorting.
- Analyzing trophic structure and the distribution of suspension feeders in relation to seabed topography and oceanic currents.
- Investigating biogeographic isolation and endemicity patterns in remote oceanic shelf ecosystems.
Strengths
- Integrates high-resolution multibeam sonar seabed mapping with biological sampling.
- Explicitly links three distinct geomorphic zones to infaunal community and trophic structure.
- Study design examines interactions between biogeography, local physical processes, and habitat.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
