The 2005 Benthic Bioregionalisation subdivided Australia's Exclusive Economic Zone into 41 bioregions, including 24 biologically unique provinces. This dataset, created by Geoscience Australia and the Australian Ocean Data Network, integrates seabed bathymetry, fish diversity, and other biophysical variables to support marine protected area planning. It includes derived maps of geomorphic features and 'seascapes' that integrate multiple spatial data layers.
Use Cases
- Designing marine protected area networks based on the 41 defined benthic bioregions.
- Predicting biodiversity distribution based on integrated 'seascape' maps of multiple spatial data layers.
- Analyzing seabed habitat characteristics using geomorphic features derived from bathymetry data.
- Supporting regional marine planning decisions using readily accessible biophysical surrogates like seabed slope, ocean production, and sediment properties.
Strengths
- Provides a structured bioregionalisation with 41 bioregions and 24 unique provinces.
- Integrates multiple existing data sources, including bathymetry, fish diversity, and seabed sediment properties.
- Created by authoritative organizations like Geoscience Australia for official marine planning programs.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
