We tested a new robust concept for the calculation of depth of investigation (DOI) that is valid for any 1D electromagnetic (EM) geophysical model. A good estimate of DOI is crucial when building geologic and hydrological models from EM data sets because the validity of the models varies strongly with data noise and the resistivity of the layers themselves. For diffusive methods, such as groundbased and airborne electromagnetic, it is not possible to define an unambiguous depth below whichdoi:10.4133/1.3614254 fatcat:mdngc7ltzvcljl4im7m6zurieq
