This pool modernizes a classic geophysical method, establishing a national capability for high-density self-potential (SP) monitoring. The system consists of a rugged, computer-controlled unit connected to an array of up to 100 non-polarizing electrodes, enabling the automatic mapping of subsurface electrical potentials across large areas or along transects.
Technology & Application
Self-potential measurements detect natural electrical fields generated by subsurface fluid flow, chemical gradients, and thermodynamic processes. This makes the technique highly valuable for:
- Investigating electrokinetic effects linked to geohazard precursors.
- Characterizing hydrogeological systems and subsurface contamination.
- Integrating with other geophysical data for comprehensive site assessment.
Integrated Monitoring & Versatility
The SP system is designed for synergy within the EPOS-NG infrastructure. It will be deployed alongside seismometers, DAS/DTSS, OBS, and piezometers to correlate electrical signals with mechanical and hydrological changes. The sensors are versatile, suitable for deployment on land, in fjords, and in other marine environments.
User Community
This advanced monitoring tool serves a wide range of stakeholders engaged in research, hazard assessment, and environmental monitoring, including universities, research institutes, public authorities, and industry partners.
