Validation of a newly developed surface NMR system

Summary The surface NMR system, Apsu, is a newly developed system, focused on the shallow subsurface. The system shows promising results regarding resolution of the shallow subsurface as well as in relation to collection of field data in less remote areas. Additionally, field measurements are fast and efficient, thus increasing the value of the system even further. The Apsu system’s capabilities of resolving the water table depth is tested through synthetic analysis. This analysis uses the standard deviation factor as a measure of the sensitivity of the system. Further, different loop configurations are tested for the system to examine their influence on the sensitivity.
