Perth Canyon Marine Park Bathymetry Grid at 40-Meter Resolution

40 percent of Australia's exclusive economic zone is covered by a network of 58 marine parks. This 40-meter resolution bathymetric grid for the Perth Canyon Marine Park was compiled from Geoscience Australia's holdings to support park management. The data release includes derived morphological surface classifications based on a two-part seafloor mapping scheme.

Use Cases

• Modeling seafloor habitats based on bathymetric slope and morphology classifications.
• Creating hillshade visualizations for geological interpretation from the combined bathymetry and hillshade geotiff.
• Informing marine park 'eco-narrative' documents that collate geomorphology, oceanography, and ecology.
• Supporting environmental management plans using collated and interpreted bathymetric data.

Strengths

• Data is gridded at a 40-meter resolution, which suggests a detailed representation of the seafloor.
• Derived from Geoscience Australia's bathymetry data holdings, indicating an authoritative source.
• Includes derived products like morphological surface categories (Plain, Slope, Escarpment) based on a published classification scheme.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is not to be used for navigational purposes, limiting its application scope.
