Ord Basin Hydrogeological Inventory for Western Australia and Northern Territory

The Ord Basin, an 8000 square kilometre intracratonic sedimentary basin on the border of Western Australia and the Northern Territory, is described in this dataset. It contains descriptive attribute information grouped into themes including location, geology, hydrogeology, groundwater, and land use. The dataset was published by the Australian Ocean Data Network and last updated in May 2026.

Use Cases

• Map groundwater management zones based on the administrative and hydrogeological boundaries described.
• Analyze the relationship between surface water features and groundwater systems using the grouped thematic attributes.
• Model sedimentary basin evolution using the described geological history, including the three depositional phases.
• Assess land use and environmental impacts on groundwater resources based on the inventory's thematic groupings.

Strengths

• Covers a defined geographic area of approximately 8000 square kilometres.
• Descriptive information is organized into 11 specific thematic groups, suggesting structured metadata.
• Includes detailed geological context, such as the basin's three synclines and up to 2500 metres of sedimentary rock.

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.
