Lord Howe Island Benthic Feeding Guild Counts from 2008 Marine Survey

A 2008 Geoscience Australia marine survey on the Lord Howe Island shelf collected data to map seabed bathymetry and characterise benthic environments. This dataset provides feeding guild counts per sample, aggregated from species-level infauna data. 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 mentioned in the description
• Study relationships between seabed environments and infauna feeding strategies based on the survey's characterisation goals
• Model marine shelf ecosystem dynamics using aggregated biological data from the described sampling

Strengths

• Derived from a dedicated marine survey conducted by Geoscience Australia, a national scientific agency
• Aggregated from species-level data, suggesting a structured taxonomic foundation
• Associated with a bathymetric grid covering 1034 sq km, providing potential for spatial correlation

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/temporal bias inherent to the single 2008 survey
