Australian Seabed Geomorphology and Bathymetry Maps for Marine Planning

Geoscience Australia's integrated marine datasets provide pre-competitive information on seabed geomorphology, sediment stability, and bathymetry. These multidisciplinary spatial layers are delivered via the Australian Marine Spatial Information System (AMSIS) to support evidence-based decisions for Australia's marine jurisdiction. The data 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 sediment stability.
• Providing regional context for environmental impact assessments using integrated spatial layers.
• Supporting marine investment decisions with pre-competitive geoscience information.

Strengths

• Data is integrated and multidisciplinary, enhancing understanding of seabed features.
• Spatial layers are accessible 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 freshness should be verified despite a last updated date of 2026-06-23.
