Geographe Marine Park Bathymetry and Seafloor Morphology Grids

Geoscience Australia provides 5-meter resolution 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 3.3 million square kilometers. This research is part of the National Environmental Science Program (NESP) Marine Biodiversity Hub Project D1.

Use Cases

• Modeling seafloor habitats based on bathymetric slope and morphological surface categories.
• Creating visualizations of underwater terrain by combining bathymetric data with hillshade images.
• Supporting the development of 'eco-narrative' documents that interpret seafloor geomorphology, oceanography, and ecology.

Strengths

• High-resolution 5-meter bathymetry grid compiled from Geoscience Australia's holdings.
• Includes derived products using a published two-part seafloor mapping morphology classification scheme (Dove et al., 2016).
• Data supports the management of a specific marine park within a national network covering 40% of Australia's exclusive economic zone.

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.
