Australian Seabed Seascape Maps for Marine Conservation and Petroleum Exploration

A national system of marine protected areas (MPAs) was designed for implementation by 2012 under the Environmental Protection and Biodiversity Conservation (EPBC) Act 1999. Geoscience Australia compiled biophysical seabed information, including bathymetry and sediment properties, to create 'seascape' maps predicting biodiversity distribution across Australia's Exclusive Economic Zone. This information provides 100% spatial coverage based on multivariate statistical methods.

Use Cases

• Identifying priority areas for marine conservation based on integrated seabed characteristics.
• Supporting petroleum exploration planning by providing reproducible, science-based seafloor classifications.
• Predicting the distribution of seabed biodiversity using multivariate statistical seascape maps.
• Informing the design of Australia's national marine protected area (MPA) system.

Strengths

• Provides 100% spatial coverage of Australia's EEZ based on objective, multivariate statistical methods.
• Integrates multiple layers of spatial data including bathymetry, geomorphology, and sediment properties.

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.
