Abstract
- Airborne EM can be used to explore to depths of 150 to 300m in fresh to moderately saline coastal plain aquifers.
- Airborne EM surveys are a realistic alternative to drilling and seismic surveys to investigate Quaternary depositional systems.
- Groundwater quality (as measured by TDS) appears to correlate to conductivity derived from airborne EM data.
- Depositional patterns can be detected and environments inferred from airborne EM if the surveys are flown at appropriate line spacing and orientation.
- Anomaly shapes and conductivity contrasts can be used to interpret likely water resource quality by combining geological and hydrological concepts.
