Australia's Maritime Jurisdiction in Bass Strait, A0 Map

Australia's Maritime Jurisdiction in Bass Strait is a map showing Australia's extended continental shelf and various maritime zones in the Bass Strait region. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789), with the extended continental shelf depiction approved by the Commission on the Limits of the Continental Shelf in April 2008. The background bathymetric image is derived from a 2009 9 arc second grid by Geoscience Australia and a 1997 grid by Smith and Sandwell.

Use Cases

• Analyze maritime boundary claims based on the depicted extended continental shelf and maritime zones.
• Study seabed topography for marine research based on the combined bathymetric background image.
• Reference jurisdictional limits for legal or policy work based on the officially approved continental shelf limits.
• Integrate as a base layer for regional marine spatial planning based on the A0-sized geospatial map.

Strengths

• Part of a standardized series of 27 maps providing consistent jurisdictional coverage.
• Based on an extended continental shelf definition officially approved by an international commission in April 2008.
• Background bathymetry combines data from Geoscience Australia (2009) and Smith and Sandwell (1997).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
