Australia's Northwest Shelf Maritime Jurisdiction Map, 2014

Geoscience Australia's map depicts Australia's maritime jurisdiction off the Northwest Shelf, updated in June 2014. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' and illustrates the continental shelf as proclaimed in the 2012 proclamation. The background combines bathymetric data from 2009 and 1997 with land imagery from NASA's Blue Marble.

Use Cases

• Analyze continental shelf boundaries based on the 2012 proclamation referenced in the description.
• Study bathymetric features of the Northwest Shelf using the combined background grid data.
• Reference maritime jurisdiction for legal or policy research based on the map's depiction of Australia's claims.
• Integrate as a base layer for marine spatial planning in the region.

Strengths

• Map is part of a formal 27-map series (GeoCat 71789) from Geoscience Australia.
• Background bathymetry is derived from specific, cited sources (2009 9 arc second grid and Smith and Sandwell, 1997).
• Jurisdictional boundaries are defined by specific legislation (Seas and Submerged Lands Act 1973) and a 2012 proclamation.

Limitations

• Data is provided only in PDF and HTML formats, limiting machine-readability and analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
