Australian Marine Bioregionalisation with Seascape Maps

41 bioregions and 24 provinces subdivide Australia's Exclusive Economic Zone based on a 2005 Benthic Bioregionalisation. Geoscience Australia created 'seascape' maps integrating multiple spatial data layers to predict biodiversity distribution. The dataset supports marine protected area network design under the Environmental Protection and Biodiversity Conservation Act.

Use Cases

• Designing representative marine protected area networks based on biophysical surrogates.
• Predicting seabed biodiversity distribution based on integrated seascape maps.
• Analyzing marine habitat characteristics based on geomorphic features and bathymetry.
• Supporting regional marine planning decisions based on fish diversity and bioregionalisation.

Strengths

• Derived from a defined bioregionalisation framework that established 41 bioregions and 24 provinces.
• Integrates multiple spatial data layers including bathymetry, seabed sediment properties, and ocean primary production.
• Created by Geoscience Australia, a national geoscience organization.

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.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Australia's EEZ.
