Perth Canyon Marine Park Bathymetry Grid at 40m Resolution

A 40-meter resolution bathymetric grid for the Perth Canyon Marine Park, part of Australia's Commonwealth marine park network covering 40% of its exclusive economic zone. Geoscience Australia compiled and processed the data from its holdings, applying a hillshade to create a panchromatic geotiff image. The dataset supports the development of 'eco-narrative' documents for park management.

Use Cases

• Mapping seafloor slope categories (Plain, Slope, Escarpment) based on the Dove et al. (2016) classification scheme mentioned in the description.
• Creating derived products for ecological interpretations based on bathymetric grids.
• Visualizing underwater terrain for marine park management plans using hillshaded geotiff images.
• Supporting research on seabed geomorphology within Commonwealth marine parks.

Strengths

• Data is gridded at an optimum resolution derived from vessel sonar systems.
• Supports a specific, semi-hierarchical seafloor morphology classification scheme (Dove et al., 2016).
• Part of a managed network of 58 marine parks covering 3.3 million square kilometres.

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.
• Row count is unknown, which may limit suitability assessment.
