Introduction to the Time Domain Electromagnetic Special Issue of JEEG

Abstract

The idea to propose a special issue on time domain electromagnetic (TEM) methods was based on my perception that recent innovations and developments, both in instrumentation and processing, deemed it time to perform a checkup on the state-of-the-art of the method. Many of these advancements address offshore and airborne applications rather than ground-based ones. For example, the popular use of the marine controlled source electromagnetic (MCSEM) method in the oil industry, undoubtedly a real “renaissance” for EM, marked a surge in the development of new devices and approaches, together with the continuous improvement in technology and processing of airborne EM data. As shown in this issue, the application of ground-based TEM has also grown, with advances in instrumentation, data processing, and its application. The papers by Xue et al. and Li …
