Arafura Basin Hydrogeological Inventory with Geological and Groundwater Attributes

An Arafura Basin dataset contains descriptive attribute information for areas bounded by spatial groundwater features. The sedimentary record spans more than 250 million years, from the late Neoproterozoic to the early Permian. The dataset is provided by the Australian Ocean Data Network via data_gov_au.

Use Cases

• Map groundwater management and use based on administrative and land use themes.
• Study hydrogeological systems based on fractured rock sandstone aquifer descriptions.
• Analyze the basin's geological history based on described rock groups and sedimentary sequences.
• Assess environmental and demographic factors related to groundwater in remote communities.

Strengths

• Descriptive topics are grouped into 11 specific themes, including hydrogeology and groundwater management.
• The dataset describes a sedimentary record spanning more than 250 million years.
• It references specific geological units like the Marchinbar Sandstone and Elcho Island Formation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes there are no detailed basin-scale studies on the hydrogeology.
