Description
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.
