Seafloor Habitat Maps for South-west Corner Marine Park at 5m and 250m Scales

Two-scale seafloor habitat maps classify five ecosystem components in the South-west Corner Marine Park, Western Australia. Modeling used 5 m and 250 m resolution bathymetry data, ground-truthing from stereo-BRUV and BOSS camera systems, and physical covariates. The work was conducted by the NESP MaC Project 2.3 and published by the Australian Ocean Data Network.

Use Cases

• Compare habitat classification accuracy based on 5 m versus 250 m resolution bathymetry data.
• Model the distribution of seagrass, macroalgae, and sessile invertebrate habitats.
• Assess prediction certainty for marine park management decision-making.
• Validate broad-scale habitat models using fine-scale, ground-truthed observations.

Strengths

• Models five distinct benthic habitat types: seagrass, macroalgae, sessile invertebrates, and two bare substrata categories.
• Includes direct comparison of fine-scale (5 m) and broad-scale (250 m) mapping outputs for the same region.
• Integrates multiple data sources: high-resolution bathymetry, in-situ camera observations, and physical oceanographic covariates.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific marine parks studied.
