Salinity of groundwater directly affects its suitability for different uses, from human consumption, agricultural use, to mineral and energy extraction. Traditionally, direct measurements of groundwater salinity at monitoring bores have been used to create salinity maps. However, drilling is expensive and logistically challenging, while leaving us with a small set of salinity measurements over large areas. Airborne electromagnetic (AEM) surveying provides a cost effective solution to this problem. We have developed a scripted geostatistical methodology, which can be repeated on a computer cluster as new AEM data are acquired or boreholes are drilled. We also provide uncertainties on the knowledge gained, allowing remote communities to manage their land and water resources effectively.
