Australian Seabed Biophysical Data for Marine Conservation Planning

Geoscience Australia compiled multiple layers of seabed data, including bathymetry and sediment properties, to provide 100% spatial coverage of Australia's Exclusive Economic Zone. This information serves as a proxy for biodiversity to support the implementation of the Environmental Protection and Biodiversity Conservation Act. The data offers a reproducible, science-based approach for marine protected area design and industry certainty.

Use Cases

• Predict biodiversity distribution based on integrated 'seascape' maps.
• Identify marine conservation priorities using multivariate statistical methods.
• Inform petroleum exploration planning based on seabed geomorphology and sediment properties.
• Support the design of marine protected areas using biophysical proxy 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 for reproducibility.
• Directly supports a national policy goal (13 MPAs nominated for the southeast region in 2006).

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Biological data is limited, relying on geological information as a proxy for biodiversity.
