Australian Marine Bioregionalisation and Seascape Maps for Biodiversity Prediction

Australia's Exclusive Economic Zone is mapped into 41 bioregions, including 24 biologically unique provinces, based on a 2005 Benthic Bioregionalisation. The dataset, created by Geoscience Australia and the Australian Ocean Data Network, integrates seabed bathymetry, geomorphic features, fish diversity, and biophysical variables like ocean primary production and seabed sediment properties.

Use Cases

• Design marine protected area networks based on mapped bioregions and geomorphic features.
• Model benthic biodiversity distribution using integrated layers of seabed slope, temperature, and sediment properties.
• Analyze the relationship between ocean primary production and fish diversity across Australia's EEZ.

Strengths

• Maps 41 distinct bioregions within Australia's EEZ, including 24 unique provinces.
• Integrates multiple spatial data layers including bathymetry, geomorphology, and fish diversity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; the core bioregionalisation is from 2005.
