Lord Howe Island shelf in New South Wales was surveyed in 2008 to map seabed bathymetry and characterize benthic environments. The dataset contains feeding guild counts per sample, aggregated from species-level infauna data collected during the survey. Data and samples were acquired using the National Facility Research Vessel Southern Surveyor.
Use Cases
- Analyze benthic community trophic structure based on feeding guild counts.
- Model relationships between seabed environments and infauna feeding groups based on colocated sampling.
- Study marine biodiversity and ecosystem function on the Lord Howe Island shelf.
Strengths
- Data originates from a dedicated 2008 marine survey by Geoscience Australia, a national scientific agency.
- Bathymetric data covers a merged grid of 1034 square kilometers.
- Infauna data is supplemented by colocated sampling of sediments, rock cores, and underwater video observations.
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.
