Perth Canyon Marine Park Bathymetry Grid at 40m Resolution

40 percent of Australia's exclusive economic zone is covered by a network of 58 marine parks spanning 3.3 million square kilometres. This dataset provides a 40-meter resolution bathymetric grid for the Perth Canyon Marine Park, compiled from Geoscience Australia's holdings and processed with a hillshade image. The data supports a new semi-hierarchical seafloor classification scheme developed under the National Environmental Science Program.

Use Cases

• Classifying seafloor morphological surfaces (Plain, Slope, Escarpment) based on the Dove et al. (2016) scheme mentioned in the description
• Creating derived products for marine park 'eco-narrative' documents based on collated bathymetry and oceanography
• Analyzing seabed geomorphology for habitat mapping based on the bathymetric grid and hillshade image
• Supporting marine biodiversity research within the Commonwealth park network based on the described data compilation effort

Strengths

• Data is integrated with a hillshade image for enhanced visualization of seafloor features
• Supports a specific, documented seafloor classification scheme (Dove et al., 2016)
• Contributes to the management of a 3.3 million square kilometre marine park network

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
