Geographe Marine Park Bathymetry Grid at 5-Meter Resolution

Australia's network of 58 marine parks covers 3.3 million square kilometres, or 40 per cent of its exclusive economic zone. This dataset provides a 5-meter resolution bathymetric grid for the Geographe Marine Park, compiled from Geoscience Australia's holdings and processed with a hillshade image. The data supports the development of 'eco-narrative' documents for park management, which interpret seafloor geomorphology, oceanography, and ecology.

Use Cases

• Seafloor habitat modeling based on bathymetric slope and morphological surface categories.
• Marine park management planning based on interpreted seafloor geomorphology and oceanography.
• Creating derivative products like hillshade visualizations based on the combined bathymetric and hillshade data.
• Classifying seafloor into Morphological Surface categories (Plain, Slope, Escarpment) based on the described classification scheme.

Strengths

• High-resolution 5-meter grid detail for precise seafloor analysis.
• Data is part of a national program managing 3.3 million square kilometres of marine parks.
• Derived using a published, two-part seafloor mapping morphology 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.
• Row count is unknown, which may limit suitability assessment.
