Lord Howe Island Benthic Feeding Guild Counts from 2008 Survey

Feeding guild counts aggregated from species-level infauna data collected during a 2008 marine survey on the Lord Howe Island shelf. Geoscience Australia acquired the data using the Research Vessel Southern Surveyor, merging bathymetry to cover a 1034 sq km grid. The underlying species data was aggregated on October 27, 2010.

Use Cases

• Analyze benthic community trophic structure based on feeding guild classifications.
• Model relationships between seabed characteristics and infauna feeding types based on the colocated sediment and habitat sampling mentioned.
• Study spatial distribution of feeding guilds across the 1034 sq km survey grid.
• Integrate feeding guild data with other survey components like bathymetry and subbottom profiles for habitat characterization.

Strengths

• Data is integrated with a detailed 1034 sq km bathymetric grid.
• Derived from a multidisciplinary survey including sediment sampling, video observation, and oceanographic measurements.
• Aggregation date (27Oct10) is specified for the source species data.

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.
