Australian Marine Seascape Maps for Conservation and Industry Planning

Geoscience Australia compiled biophysical seabed data to support marine conservation planning under the EPBC Act 1999. The dataset provides 100% spatial coverage of Australia's Exclusive Economic Zone, integrating layers like bathymetry, geomorphology, and sediment properties. It was used to nominate 13 Marine Protected Areas in the southeast region by 2006 and aims to complete a national representative system by 2012.

Use Cases

• Predicting seabed biodiversity distribution based on integrated seascape maps.
• Identifying conservation priorities using a reproducible, science-based approach.
• Providing spatial certainty for petroleum exploration based on objective seabed classification.
• Supporting the design of Marine Protected Areas using biophysical proxy data.

Strengths

• Provides 100% spatial coverage of Australia's Exclusive Economic Zone.
• Based on objective, multivariate statistical methods.
• Integrates multiple data layers including bathymetry, geomorphology, and sediment properties.
• Directly supports a legislative framework (EPBC Act 1999) with a 2012 target.

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, focusing on Australia's EEZ.
