Maritime Jurisdiction Map of Tasmania with Bathymetric Background

One of 27 maps in the Australia's Maritime Jurisdiction Map Series, this A0 portrait format PDF depicts maritime zones and the extended continental shelf around Tasmania. It was produced by the Australian Ocean Data Network, incorporating bathymetric data from 2009 and land imagery from NASA's Blue Marble. The map reflects the continental shelf limits approved by the Commission on the Limits of the Continental Shelf in April 2008.

Use Cases

• Analyze the spatial extent of Australia's maritime jurisdiction and continental shelf boundaries around Tasmania for legal or policy research.
• Use the bathymetric background layer derived from 2009 and 1997 data sources for oceanographic or geological studies of the seafloor.
• Compare maritime zone boundaries (e.g., exclusive economic zone) depicted on this map with other jurisdictional datasets for validation.
• Integrate the map's geographic features as a base layer for marine spatial planning or environmental impact assessments in the Tasman Sea region.

Strengths

• Part of a standardized series of 27 constituent maps providing consistent jurisdictional coverage.
• Incorporates authoritative bathymetric data from a 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Based on the officially approved continental shelf limits from April 2008, providing a legal foundation.

Limitations

• The underlying bathymetric and topographic grid data is from 2009 or earlier, which may not reflect recent seafloor changes.
• The map is a static PDF, requiring extraction for quantitative geospatial analysis, and specific data columns/attributes are unknown.
• Spatial coverage is limited to the area around Tasmania, excluding features like the Macquarie Ridge as noted.

Provenance

Source

Australian Ocean Data Network, as part of the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789).

Collection Method

Cartographic production based on approved legal boundaries and synthesized background geospatial data.

Time Range

The jurisdictional boundaries reflect the April 2008 approval; background imagery and bathymetry are from 2009 and 1997.

Freshness

The dataset record was last updated on 2026-04-04, though the core map data reflects a 2008 approval and 2009 background data.

Geography

Focuses on Australia's maritime jurisdiction around Tasmania, including the South Tasman Rise and Victoria.
