A remote sensing technique that monitors the electrical resistance of soils in a restricted volume near the surface of an archaeological site; buried walls or features can be detected by changes in the amount of resistance registered by the resistivity meter.
Electromagnetic induction sensing (EMI or more commonly. referred to as simply EM) and other soil conduction devices. (e.g. those that use resistivity) can be used to map apparent. soil conductivity (ECa). The most commonly used instruments for plant rooting depth. measurement are the Geonics EM38-MK2 and the DUALEM-2.
