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

The South-west Corner Marine Park in southern Western Australia contains seafloor habitat maps classifying five ecosystem components: seagrass, macroalgae, sessile invertebrates, bare consolidated substrata, and bare unconsolidated substrata. Modeling was conducted by the NESP MaC Project 2.3 at two spatial scales using 5 m and 250 m resolution bathymetry data, ground-truthing observations from camera systems, and physical covariates. The dataset was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Comparing habitat classification accuracy based on 5 m versus 250 m resolution bathymetry inputs.
• Mapping the distribution of five broad benthic habitat types for marine protected area management.
• Assessing prediction certainty for habitat models in consultation with management end-users.
• Analyzing the effects of spatial covariate scale on ecosystem component modeling outcomes.

Strengths

• Models five distinct benthic habitat classes (seagrass, macroalgae, sessile invertebrates, bare consolidated substrata, bare unconsolidated substrata).
• Includes comparative analysis at two defined spatial resolutions: 5 m and 250 m.
• Integrates multiple data sources: high-resolution multibeam bathymetry, ground-truthing imagery, and physical covariates.
• Methodology is documented in publicly available NESP MaC Project final reports.

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 park study area.
