Gifford Marine Park Bathymetry Grid at 30-Meter Resolution

Geoscience Australia compiled bathymetry data for Australia's marine park network, which covers 3.3 million square kilometres. The data release includes a 30-meter resolution bathymetric grid and derived morphological surface classifications for the Gifford Marine Park. This work supports marine park management plans effective from July 2018.

Use Cases

• Model seafloor geomorphology based on bathymetric slope classifications mentioned in the description
• Analyze marine habitat distribution based on interpreted seafloor morphology and oceanography
• Support marine park management planning using collated environmental data and eco-narratives

Strengths

• Bathymetry grids are processed at an optimum resolution derived from vessel sonar systems.
• Data supports a 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.
• The dataset is not to be used for navigational purposes, limiting its application scope.
