Bathymetry Grid of Perth Canyon Marine Park at 40-Meter Resolution

40-meter resolution bathymetric grid for the Perth Canyon Marine Park, part of Australia's 3.3 million square kilometre marine park network. Geoscience Australia compiled this data from its holdings, processed to an optimum resolution based on sonar systems, and combined it with a hillshade image. The data supports the development of 'eco-narrative' documents for park management under the National Environmental Science Program.

Use Cases

• Classifying seafloor morphology into Plain, Slope, and Escarpment categories based on the Dove et al. (2016) scheme mentioned in the description.
• Generating derived products for ecological interpretations and oceanographic studies referenced in the eco-narrative documents.
• Visualizing underwater terrain by combining bathymetric data with hillshade imagery as described.
• Supporting marine park management plans that came into effect on 1 July 2018, as stated in the description.

Strengths

• Data is part of a national network covering 3.3 million square kilometres of Commonwealth waters.
• Gridded at an optimum resolution based on vessel sonar systems, as described.
• Supports a new semi-hierarchical seafloor classification scheme (Dove et al., 2016).

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.
