Carnarvon Basin Hydrogeological Inventory for Western Australia

A 1,000 km sedimentary basin along Western Australia's coast contains descriptive attributes grouped into 11 themes, including hydrogeology and groundwater management. Over 80% of the basin is offshore in water depths up to 4,500 meters, with up to 15,000 meters of sedimentary infill in the northern section. The dataset, provided by the Australian Ocean Data Network, was last updated in April 2026.

Use Cases

• Model groundwater flow and resources based on hydrogeological and groundwater feature data
• Analyze the relationship between surface water, geology, and land use for environmental impact studies
• Support hydrocarbon exploration by studying the basin's sedimentary history and structural features
• Assess groundwater management strategies using administrative and demographic information

Strengths

• Covers a large geographic area stretching over 1,000 km from Geraldton to Karratha
• Attributes are organized into 11 distinct thematic groups for structured analysis
• Describes a basin with significant hydrocarbon resources and a complex geological history shaped by multiple extensional episodes

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is provided in PDF format, which may hinder direct computational analysis
