Australian Seabed Maps for Marine Spatial Planning and Risk Assessment

Geoscience Australia's pre-competitive marine geoscience data includes bathymetry compilations, seabed geomorphology, and sediment stability maps. The integrated datasets are delivered via the Australian Marine Spatial Information System (AMSIS) to support planning and investment decisions across ocean sectors. A related poster was presented at the Australian Marine Science Association conference in July 2025.

Use Cases

• Designing marine surveys based on bathymetric and geoscience maps.
• Identifying areas suitable for offshore infrastructure based on seabed characteristics.
• Providing regional context for environmental impact assessments using integrated spatial layers.
• Supporting marine spatial planning decisions with multidisciplinary seabed feature data.

Strengths

• Data is integrated and multidisciplinary, enhancing understanding of seabed features.
• Spatial data is delivered via a web-based interactive mapping and decision support system (AMSIS).
• Information supports evidence-based decisions consistent with government policies and regulations.

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 marine jurisdiction.
