Geographe Marine Park Bathymetry Grid at 5-Meter Resolution

Geoscience Australia provides a 5-meter resolution bathymetry grid for Geographe Marine Park. The data release supports the management of Australia's network of 58 marine parks, which cover 3.3 million square kilometres. The grid was created by compiling and processing Geoscience Australia's bathymetric data holdings.

Use Cases

• Model seafloor geomorphology based on the bathymetric grid and derived hillshade.
• Classify seafloor slope into morphological surfaces (Plain, Slope, Escarpment) based on the described classification scheme.
• Support ecological interpretations and 'eco-narrative' development for marine parks based on bathymetric data.

Strengths

• Data is derived from Geoscience Australia's authoritative bathymetry data holdings.
• Grid resolution is optimized based on the vessel's sonar system, suggesting tailored processing.
• Supports the management of a defined network of 58 marine parks 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.
• The dataset is not to be used for navigational purposes, limiting its application scope.
