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' (GeoCat 71789). The map shows the continental shelf as proclaimed in 2012, with a background bathymetric image derived from 2009 and 1997 grids.

Use Cases

• Analyze maritime boundary definitions based on the proclaimed continental shelf limits.
• Study bathymetric features of the Northwest Shelf region based on the combined background grid data.
• Reference legal and administrative maritime zones for regional planning based on the jurisdictional map.

Strengths

• Map is part of a standardized national series of 27 constituent maps.
• Background bathymetry combines data from a 2009 9 arc second grid and a 1997 grid by Smith and Sandwell.
• Jurisdictional boundaries are defined by a specific 2012 proclamation under the 1973 Seas and Submerged Lands Act.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
