Australia's Antarctic Maritime Jurisdiction Map with Bathymetric Background

One of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map depicts Australia's extended continental shelf approved by the Commission on the Limits of the Continental Shelf in April 2008, along with treaties and various maritime zones. Background imagery combines a 2009 9 arc second bathymetric and topographic grid with a 1997 grid and NASA's Blue Marble land imagery.

Use Cases

• Analyze maritime zone boundaries based on treaties and continental shelf limits mentioned in the description
• Study bathymetric features using the combined 2009 and 1997 background grids described
• Create derivative cartographic products for the Australian Antarctic Territory based on the provided map series
• Reference legal maritime jurisdictions for research in international law or ocean governance

Strengths

• Part of a standardized series of 27 maps (GeoCat 71789) providing consistent coverage
• Background bathymetry derived from specific, cited sources: a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell
• Includes multiple legally defined features: extended continental shelf (approved April 2008), treaties, and maritime zones

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
• Data may reflect geographic and temporal bias inherent to the specific treaties and 2008 shelf approval
