Geoscience Australia conducted a marine survey on the Lord Howe Island shelf in 2008 to map seabed bathymetry and characterize benthic environments. This dataset provides feeding guild counts per sample, aggregated from species-level data collected during that survey. The 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 benthic habitat health and ecological function based on aggregated guild data.
- Correlate feeding guild distributions with seabed bathymetry and sediment data mentioned in the survey description.
Strengths
- Data originates from a dedicated marine survey by Geoscience Australia using a national research vessel.
- Bathymetric data from the survey was merged with pre-existing data to generate a grid covering 1034 sq km.
- Feeding guild counts are aggregated from detailed species-level data.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to the single 2008 survey.
