SeaMap Tasmania Bathymetric Contours for Coastal Waters

Bathymetric contours at a 5-meter interval detail the seabed from Tasmania's low water mark to 40 meters depth or 1.5 kilometers offshore. The contours were developed to support coastal management objectives under The Living Marine Resources Act 1995. Data is provided by the Australian Ocean Data Network and was last updated in July 2026.

Use Cases

• Modeling coastal erosion and sediment transport based on detailed seabed topography.
• Planning marine infrastructure projects based on water depth and distance from shore.
• Assessing habitat suitability for marine species based on bathymetric gradients.
• Supporting maritime navigation and safety planning based on underwater terrain.

Strengths

• Contours are provided at a detailed 5-meter depth interval.
• Data coverage is defined by specific legal and geographic boundaries (LWM to 40m/1.5km).
• Data is intended for official use under The Living Marine Resources Act 1995.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total spatial extent are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing only on Tasmanian coastal waters.
