Perth Canyon Marine Park Bathymetry Grid at 40-Meter Resolution

Geoscience Australia compiled this 40-meter resolution bathymetry grid for the Perth Canyon Marine Park. The data release supports the management of Australia's network of 58 marine parks, covering 40 percent of the Commonwealth's exclusive economic zone. The grid is used to develop seafloor geomorphology interpretations under the National Environmental Science Program.

Use Cases

• Modeling seafloor slope and morphology based on the Dove et al. classification scheme mentioned in the description
• Creating derived hillshade products for visualizing underwater terrain
• Supporting ecological and oceanographic interpretations for marine park 'eco-narratives'
• Analyzing habitat characteristics for biodiversity assessment within the park network

Strengths

• Data is gridded at a 40-meter resolution, providing detail for seafloor analysis
• Supports management of a network of 58 marine parks covering 3.3 million square kilometers
• Based on a defined two-part seafloor mapping morphology approach (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
