Australian Seabed Seascape Maps for Marine Conservation Planning

Geoscience Australia compiles biophysical seabed data as a proxy for biodiversity in Australia's Exclusive Economic Zone. The dataset includes bathymetry, geomorphology, acoustic properties, sediment properties, slope, and sediment mobilisation layers, integrated into 'seascape' maps. This information supports the implementation of the EPBC Act 1999 and the design of a national marine protected area system.

Use Cases

• Predicting seabed biodiversity distribution based on integrated seascape maps.
• Identifying conservation priorities using a reproducible, science-based approach.
• Providing spatial certainty for oil and gas industry operations within marine protected areas.
• Characterizing seafloor habitats using multivariate statistical methods on bathymetry and sediment data.

Strengths

• Provides 100% spatial coverage of Australia's Exclusive Economic Zone.
• Integrates multiple data layers including bathymetry, geomorphology, and sediment properties.
• Based on objective, multivariate statistical methods.
• Supports a specific policy goal: establishing a national representative system of marine protected areas by 2012.

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.
