Australia's Coral Sea Maritime Jurisdiction Map

Australia's Maritime Jurisdiction in the Coral Sea (North) is a thematic map depicting Australia's extended continental shelf and various maritime zones in the northern Coral Sea. It is one of 27 constituent maps in the Australia's Maritime Jurisdiction Map Series, produced by the Australian Ocean Data Network. The map background incorporates bathymetric data from 2009 and land imagery from NASA's Blue Marble.

Use Cases

• Analyze the spatial extent of Australia's extended continental shelf boundary as approved in 2008.
• Study the relationship between maritime jurisdiction zones and underlying bathymetric features derived from the 2009 9 arc-second grid.
• Compare treaty-defined maritime boundaries against background land imagery from NASA's Earth Observatory.
• Integrate this map layer with other marine datasets using the defined administrative boundaries for the Au Qld region.

Strengths

• Part of a standardized series of 27 constituent maritime jurisdiction maps.
• Incorporates authoritative bathymetric data from a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Based on an extended continental shelf submission approved by the UN Commission in April 2008.

Limitations

• Data is provided only in PDF and HTML formats, limiting machine-readability and direct analysis.
• Specific columnar data, row counts, and file sizes are unknown.
• The map is static and its update frequency is unclear, though the platform record was last updated in April 2026.
