Australia's Maritime Jurisdiction Map for the Northwest Shelf

One map from the Australia's Maritime Jurisdiction Map Series, depicting the extended continental shelf approved in 2008, treaties, and maritime zones off the Northwest Shelf. The background combines bathymetric data from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell, with land imagery from NASA's Blue Marble. The map is an A0-sized PDF downloadable via the Australian Ocean Data Network.

Use Cases

• Visualizing maritime legal boundaries based on treaties and the 2008 continental shelf approval.
• Analyzing seabed topography based on the combined 2009 and 1997 bathymetric grids.
• Studying the spatial relationship between Australia's maritime zones and background land imagery from NASA's Blue Marble.

Strengths

• Part of a standardized 27-map series (GeoCat 71789), suggesting consistent methodology.
• Background bathymetry is derived from two specific, cited sources: a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.
• Includes multiple legal and geographic layers: extended continental shelf, treaties, and various maritime zones.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific sources and 2008 legal context.
