AusSeabed Bathymetry Survey Acquisitions Coverage Database

A live database of polygon extents for bathymetry data acquisitions, updated regularly via the AusSeabed Marine Data Portal. The dataset identifies surveys conducted by various organizations across coastal, continental shelf, and deep-sea locations intersecting Australia's marine jurisdiction, including the Australian Antarctic Territory. Each polygon contains metadata describing survey details, though extents may not be fully representative due to the data gridding process.

Use Cases

• Mapping seabed survey coverage based on polygon extents intersecting Australia's marine jurisdiction.
• Identifying data availability and contact details for bathymetry surveys not held by Geoscience Australia.
• Supporting the computation of Percent Mapped assessments for Australian marine jurisdictions.
• Discovering bathymetry data acquisitions spanning coastal, shelf, and deep-sea locations.

Strengths

• Live database updated regularly as coverage details are supplied by collaborators.
• Includes polygon extents for surveys intersecting Australia's marine jurisdiction, including the Antarctic Territory.
• Contains metadata describing survey details and contact information for external data.

Limitations

• Polygon extents may not represent true survey coverage due to the data gridding process.
• Row count and column-level documentation are unknown, limiting suitability assessment.
• Excludes information provided under Restricted and Exclusive licenses.
