Australian Marine Seascape Maps for Biodiversity Prediction and Petroleum Exploration

Australia's Exclusive Economic Zone (EEZ) is the focus of this dataset compiled by Geoscience Australia. It integrates multiple layers of biophysical seabed information, including bathymetry and sediment properties, to create 'seascape' maps for predicting biodiversity distribution. The data supports the implementation of the Environmental Protection and Biodiversity Conservation (EPBC) Act 1999 and marine protected area planning.

Use Cases

• Identifying marine conservation priorities based on integrated seabed geomorphology and acoustic data.
• Predicting seabed biodiversity distribution using multivariate statistical seascape classification.
• Informing petroleum exploration risk assessments based on reproducible seafloor type classification.
• Supporting the design of marine protected areas (MPAs) using proxy data for seabed biodiversity.

Strengths

• Provides 100% spatial coverage of Australia's EEZ based on objective, multivariate statistical methods.
• Integrates multiple data layers including bathymetry, geomorphology, acoustic properties, and sediment properties.
• A total of 13 Marine Protected Areas (MPAs) were nominated for the southeast region in 2006, providing a concrete application context.

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.

Collection Method

Data compiled from biophysical seabed surveys and integrated using statistical methods to create seascape maps.

Time Range

The EPBC Act was passed in 1999, with MPA nominations noted for 2006 and a target for a representative system by 2012.
