Electrical resistivity tomography

A plot on a graph showing groundwater data in depth and ohms.

Detailed Description

Example of one of one of the geophysical methods (Electrical resistivity tomography) used to detect the freshwater-saltwater interface and the location where freshwater flows onto a reef. Superimposed are the results from chemical analysis of groundwater samples that show that salinity measurements correspond with freshwater, mixing an saline zones.
