Australian Seabed Biophysical Data for Marine Protected Area Planning

Geoscience Australia compiled biophysical seabed information to support marine conservation planning under the Environmental Protection and Biodiversity Conservation (EPBC) Act 1999. The data includes bathymetry, geomorphology, acoustic properties, sediment properties, slope, and sediment mobilisation, providing 100% spatial coverage of Australia's Exclusive Economic Zone. This information is used as a proxy for seabed biodiversity and to create integrated 'seascape' maps for predicting biodiversity distribution.

Use Cases

• Predicting seabed biodiversity distribution based on integrated seascape maps.
• Informing marine protected area (MPA) design based on multivariate statistical analysis of seabed characteristics.
• Providing certainty for petroleum exploration activities based on reproducible, science-based seafloor classification.

Strengths

• Provides 100% spatial coverage of Australia's Exclusive Economic Zone (EEZ).
• Integrates multiple layers of spatial data including bathymetry and sediment properties.
• Based on objective, multivariate statistical methods for classification.

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.
