AusSeabed Bathymetry Compilations: Coverage Database for Australia's Marine Jurisdiction

AusSeabed's coverage database contains polygon extents of bathymetry data acquisitions from multiple organizations and countries. It is a live resource updated regularly via the AusSeabed Marine Data Portal, identifying data spanning coastal, continental shelf, and deep sea locations. The database is augmented by collaborators who share knowledge of data availability with the broader marine community.

Use Cases

• Map bathymetry data availability for marine research planning based on polygon extents.
• Identify data custodians and contact details for data not held by Geoscience Australia.
• Analyze spatial coverage of seabed surveys across coastal, shelf, and deep-sea environments.
• Support marine spatial planning and jurisdictional assessments based on compilation intersections with Australia's marine jurisdiction.

Strengths

• Data is live and regularly updated as coverage details are supplied by collaborators.
• Coverage includes areas intersecting with Australia's marine jurisdiction, including the Australian Antarctic Territory.
• Compilations are generated from multiple survey acquisitions by a wide range of organizations and countries.

Limitations

• Polygons may not be representative of the true survey extent due to the data gridding process.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
