Maritime Jurisdiction Map of Macquarie Island with Bathymetry

One of 27 maps in Australia's Maritime Jurisdiction Map Series, this thematic map depicts the extended continental shelf and maritime zones around Macquarie Island. The Australian Ocean Data Network produced it, with bathymetric background derived from 2009 and 1997 grids. The map was last updated in April 2026.

Use Cases

• Analyze the spatial extent of Australia's extended continental shelf boundary approved in 2008.
• Overlay maritime zone data (e.g., Exclusive Economic Zone) with bathymetric imagery for habitat studies.
• Use the Lambert Conformal Conic Projection for accurate area measurements of jurisdictional claims.

Strengths

• Part of a standardized series of 27 constituent maps for consistent national coverage.
• Integrates bathymetric data from two authoritative sources (GA 2009 grid and Smith & Sandwell 1997 grid).
• Depicts multiple legally defined features: continental shelf, treaties, and various maritime zones.

Limitations

• Data is provided only as a static PDF/A0 map, limiting direct geospatial analysis without digitization.
• The underlying bathymetric grid data is from 2009 and 1997, which may not reflect recent seafloor changes.
• No attribute table or column data is provided with the map file for quantitative analysis.

Time Range

Jurisdictional data reflects the April 2008 Commission approval; bathymetry from 1997 and 2009.

Freshness

Updated in April 2026, but core jurisdictional data is based on a 2008 commission approval.
