Substances such as ice have high resistivity, meaning electricity doesn’t flow through them easily. Daniela Hernandez, WSJ, "Climate’s Big Unknown: What’s Happening Beneath Antarctica’s Ice?," 29 Dec. 2018 The tool discriminates between different materials based on something called resistivity—a measure of how easily electrical current can flow. Daniela Hernandez, WSJ, "Climate’s Big Unknown: What’s Happening Beneath Antarctica’s Ice?," 29 Dec. 2018 To get a better idea of what lies below the property, Muhlestein used a technique called electrical resistivity mapping to get 3-D images of the property down to 30 feet below ground. Brendan Gibbons, San Antonio Express-News, "Friesenhahn Cave just outside S.A. yielded treasure trove of Ice Age fossils," 17 Dec. 2017 Measurements of electrical resistivity – how strongly a material opposes the flow of an electric current – helped us determine which parts of the tunnel were filled. Jamie Pringle And Peter Doyle, Smithsonian, "This Newly Excavated Underground Tunnel Reveals How 83 German Officers Escaped a World War II Prison Camp," 11 Aug. 2017 Those maps were combined with resistivity measurements and, later, the magnetization data from bore samples. Chris Lee, Ars Technica, "Plugging in to a volcano: Geothermal power and the science that enables it," 11 Oct. 2017 While no one has been able to go inside the tunnel yet, the discovery was made through a method known as electrical resistivity tomography, which creates subterranean images. National Geographic, "New Tunnel Discovered Under Ancient Pyramid," 7 July 2017 There is also a nice journal article that looks at resistivity of aluminum. Rhett Allain, WIRED, "Physics of the Electromagnetic Ring Launcher," 10 Jan. 2014
