Geographe Marine Park Bathymetry Grid at 5-Meter Resolution

Geoscience Australia compiled this 5-meter resolution bathymetry grid for the Geographe Marine Park, part of Australia's network of 58 marine parks covering 3.3 million square kilometers. The data release includes a panchromatic geotiff image combining bathymetry with hillshade and derived morphological surface classifications based on slope. This research was supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub.

Use Cases

• Modeling seafloor geomorphology based on the described slope classification scheme (Plain, Slope, Escarpment).
• Supporting ecological interpretations and 'eco-narrative' development for marine park management.
• Creating derived products for habitat mapping based on bathymetric data and hillshade imagery.
• Analyzing seabed characteristics within a Commonwealth marine park setting.

Strengths

• High-resolution 5-meter grid derived from Geoscience Australia's bathymetry data holdings.
• Integrated product combining bathymetric data with a hillshade image for enhanced visualization.
• Supports a national network of 58 marine parks covering 40% of Australia's exclusive economic zone.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
