Geographe Marine Park Bathymetry and Seafloor Morphology Grids

Geoscience Australia provides bathymetry grids and derived morphological surface classifications for the Geographe Marine Park. The data supports the management of Australia's network of 58 marine parks, which cover 40 percent of the nation's exclusive economic zone. This release includes 5-meter resolution bathymetric grids processed from sonar data and a classification of seafloor slope into Plain, Slope, and Escarpment categories.

Use Cases

• Modeling seafloor habitats based on bathymetry and slope classifications described in the dataset.
• Supporting marine park management plans by providing interpreted environmental data on geomorphology.
• Creating derived products like hillshade visualizations from the combined bathymetric and panchromatic geotiff data.

Strengths

• Data is gridded at a 5-meter resolution, suggesting a high level of spatial detail.
• Based on a documented, semi-hierarchical seafloor classification scheme (Dove et al., 2016).
• Contributes to the management of a park network covering 3.3 million square kilometers.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes the dataset is not to be used for navigational purposes, indicating potential accuracy limitations for that use.
