Application of biophysical information to support Australia's representative marine protec

Geoscience Australia created a map subdividing Australia's Exclusive Economic Zone into 41 bioregions, including 24 unique provinces. This dataset integrates seabed bathymetry, fish diversity, and biophysical variables like ocean primary production and sediment properties. It was developed to support the representative marine protected area program under the Environmental Protection and Biodiversity Conservation Act.

Use Cases

• Predicting seabed biodiversity distribution based on integrated layers of spatial data.
• Designing networks of marine protected areas based on biophysical surrogates like geomorphic features.
• Analyzing the relationship between oceanographic variables (e.g., temperature, primary production) and benthic bioregions.

Strengths

• Derived from a Benthic Bioregionalisation that defines 41 distinct bioregions.
• Integrates multiple spatial data layers including seabed bathymetry, sediment properties, and ocean temperature.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au.

Geoscience Australia Data

Collection Method

Existing seabed bathymetry data were processed to produce a geomorphic features map, which was integrated with fish diversity and other biophysical data.

Time Range

The core Benthic Bioregionalisation is from 2005.
