Australian Seabed Biophysical Data for Marine Conservation and Industry Planning

Geoscience Australia compiled biophysical seabed information for Australia's Exclusive Economic Zone to support marine conservation planning under the EPBC Act 1999. The data includes bathymetry, geomorphology, acoustic properties, sediment properties, slope, and sediment mobilisation, integrated into 'seascape' maps. This information provides 100% spatial coverage of the EEZ based on objective, multivariate statistical methods.

Use Cases

• Predicting seabed biodiversity distribution based on integrated seascape maps.
• Identifying marine conservation priorities based on reproducible, multivariate statistical methods.
• Providing spatial certainty for petroleum exploration activities based on objective seabed characterisation.
• Supporting the design of Marine Protected Areas (MPAs) based on biophysical proxy data.

Strengths

• Provides 100% spatial coverage of Australia's Exclusive Economic Zone.
• Based on objective, multivariate statistical methods for seabed classification.
• Integrates multiple layers of spatial data (bathymetry, geomorphology, sediment properties, etc.).
• Supports a reproducible, science-based approach for conservation planning.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Biological data is limited; the dataset uses biophysical information as a proxy for biodiversity.
• Freshness should be verified; last metadata update was 2026-06-23.
