Geophysical tools enable us to see beneath the Earth's surface and are used in many fields, like archaeology, environmental and engineering studies. Although originally designed for deep underground exploration, they are now being used to study much shallow areas. This requires high precision and pushes the limits of current technology. To meet this challenge and better train students, the University of Toledo created the Environmental Geophysics Signal Simulation Space (EGS3), a unique outdoor laboratory at the Stranahan Arboretum, Toledo. EGS3 provides a realistic testing ground for improving how we use geophysics in shallow subsurface studies. The site includes two plots containing various buried objects that represent real-world targets such as pipes, and cultural artifacts. The facility allows researchers and students to test different geophysical techniques—like electromagnetic imaging (EMI), and magnetic surveys. This presentation shows results that emphasize the need to combine multiple methods for detecting different types of buried objects. The use of new data processing techniques like the [1] inversion of low induction EMI methods and [2] application of Normalized Source Strength for processing magnetics data are used to show how newer data processing tools can help scientists better adapt modern geophysical technologies to shallow subsurface work.
