Habitat modelling of 'functional reef' and broad-scale ecosystem components for temperate

Two Bayesian habitat models for temperate Australian shelf waters south of the Tropic of Capricorn. The Functional Reef model classifies seabed as reef or non-reef, while the Ecosystem Component model distinguishes five broad habitat types. Outputs are based on 250m resolution bathymetry, ground-truthed benthic imagery, and oceanographic covariates.

Use Cases

• Predicting the distribution of 'functional reef' habitats based on bathymetry and oceanographic variables.
• Classifying seafloor into five broad ecosystem components (e.g., seagrass, macroalgae) for regional habitat mapping.
• Ground-truthing and validating broad-scale benthic habitat maps using annotated imagery from stereo-BRUV and BOSS systems.

Strengths

• Models are based on ground-truthing observations from stereo-BRUV and BOSS camera systems.
• Covariates include physical oceanographic datasets smoothed to a consistent 250m resolution.
• The modelled area covers all shelf waters (<250m depth) in southern Australia, providing a broad spatial scope.

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 bias inherent to the specific sampling design and ground-truthing locations.
