Gifford Marine Park Bathymetry Grid at 30-Meter Resolution

A 30-meter resolution bathymetric grid for Gifford Marine Park, part of Australia's network of 58 marine parks covering 3.3 million square kilometers. The data was compiled and processed by Geoscience Australia from its bathymetry holdings and is released as a panchromatic GeoTIFF image combining bathymetry with a hillshade. This release supports the development of 'eco-narrative' documents for park management, which interpret seafloor geomorphology, oceanography, and ecology.

Use Cases

• Seafloor habitat modeling based on derived slope classifications (Plain, Slope, Escarpment).
• Marine park management planning based on interpreted bathymetric data and hillshade products.
• Geomorphological analysis of the seafloor using the two-part classification scheme referenced in the description.

Strengths

• Data is part of a national network covering 40% of Australia's exclusive economic zone (excluding Antarctic Territory).
• Grid is processed at an optimum resolution based on the vessel's sonar system.
• Includes derived morphological surface categories (Plain, Slope, Escarpment) based on a published scientific scheme.

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.
