Physical Surrogates for Benthic Organisms in the Southern Gulf of Carpentaria

A report testing links between physical and biological datasets for benthic habitats in Australia's Gulf of Carpentaria. The analysis is based on physical factors like sediment composition, mobility, water depth, and organic carbon flux. Results from the Australian Ocean Data Network allow extrapolation to the wider Northern Planning Area for marine management.

Use Cases

• Predict benthic macrofauna distribution based on sediment composition and mobility data.
• Model species-environment relationships for marine habitat mapping using water depth and seabed morphology.
• Extrapolate small-scale physical-biological links to broader marine planning areas like the Northern Planning Area.
• Apply cluster analysis for seabed habitat classification based on abiotic attributes.

Strengths

• Analysis incorporates process-based indices like sediment mobility alongside static factors.
• Relationships are tested against the distribution and diversity of benthic macrofauna.
• Findings are applied to the whole Northern Planning Area for marine management.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Uncertainties in extrapolating physical relationships across broader gradients are noted.
