Hydro-Geophysical Monitoring Data for Saline Aquifer Study in Sardinia

Raw cross-hole time-lapse Electrical Resistivity Tomography (ERT) data and inversion results from a field study in Sardinia. The data package supports research into freshwater-saltwater interactions in porous media, with applications for underground freshwater storage. It was produced by Klaus Haaken of the University of Bonn and accompanies a published scientific manuscript.

Use Cases

• Calibrating density-dependent flow and transport models based on field ERT data.
• Analyzing freshwater-saltwater interface dynamics based on time-lapse ERT monitoring.
• Validating ERT inversion methodologies using raw cross-hole field data.
• Studying aquifer storage techniques in semi-arid regions based on the Sardinia case study.

Strengths

• Includes raw field data alongside processed inversion results, enabling reproducibility.
• Focuses on a real-world case study in Sardinia, providing context-specific insights.
• Combines multiple data types: raw ERT measurements, field data, and modeling outputs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
