Australia's Antarctic Maritime Jurisdiction Map with Bathymetric Background

A constituent map from the 'Australia's Maritime Jurisdiction Map Series' depicting maritime zones off the Australian Antarctic Territory. The map shows Australia's extended continental shelf as approved by the Commission on the Limits of the Continental Shelf in April 2008, along with treaties and various maritime zones. The background bathymetric image is derived from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble.

Use Cases

• Analyze maritime boundary claims based on the depicted extended continental shelf and zones.
• Study bathymetric features for oceanographic research using the described background grid data.
• Create reference materials for Antarctic policy discussions based on treaty and jurisdictional information.
• Assess cartographic representations of territorial claims in polar regions.

Strengths

• Map is part of a standardized national series (GeoCat 71789), suggesting consistent production.
• Background integrates specific, cited bathymetric data sources from 2009 and 1997.
• Depicts legally defined maritime zones approved by an international commission in 2008.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
