Australia's Antarctic Maritime Jurisdiction Map with Bathymetric Background

A geospatial map depicting Australia's maritime jurisdiction off the Australian Antarctic Territory. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789) and shows the extended continental shelf approved in 2008, treaties, and maritime zones. The background bathymetric imagery combines a 2009 9 arc-second grid from Geoscience Australia with a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundaries and treaties based on the depicted jurisdictional zones.
• Study the extent of the continental shelf based on the 2008 Commission approval.
• Use the bathymetric background for oceanographic or topographic reference in the region.

Strengths

• Part of a defined 27-map series (GeoCat 71789) providing structured context.
• Background bathymetry is derived from specific, cited sources (2009 GA grid and 1997 Smith and Sandwell grid).
• Map dimensions (3400mm x 1050mm) are specified for a 42-inch plotter, indicating a high-resolution output.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a static PDF/HTML map, limiting direct machine-readability and analysis.
• Freshness should be verified; the last metadata update is listed as 2026-04-20, but the underlying bathymetric data sources are from 2009 and 1997.
