This research aims to tackle the issue of inconvenient clock synchronization in marine controlled-source electromagnetic (MCSEM) operations with coaxial cables. This clock synchronization method in the paper can be applied to scenarios where coaxial cables are used for MCSEM operations. We hope that in the future, MCSEM transmitters can be deployed on a wider variety of ships to reduce costs and broaden the scope of applications.

Current borehole receivers only measure a single parameter of the magnetic field component, which does not meet the special requirements of controlled-source electromagnetic (CSEM) methods. This study proposes a borehole electromagnetic receiver that realizes synchronous acquisition of the vertical electric field component and three-axis orthogonal magnetic field components. Results of the experiments show that our system functioned adequately and that high-quality CSEM signals were obtained.

An electromagnetic transmitter sends an electromagnetic wave to the seabed; the receiver located on the seafloor receives the electromagnetic wave which carries the information of the geosphere.
In this paper, an algorithm is proposed to improve the current quality of marine electromagnetic transmitters. It has an anomaly detection function for the unstable part of the transmitting current. Our results show that the instability of transmitting-current data can cause obvious anomalies.

High-power transmitters have been playing a significant role in deep electromagnetic exploration. However, a high-power transmitter needs high-voltage support, which is a potential risk for researchers. According to the actual situation of field exploration, we designed a wireless monitoring system. The system offers two advantages, the first of which is high security; the second advantage is simple operation.

We believe that our study full-waveform voltage and current recording device for MTEM transmitters makes a significant contribution to the literature because this full-waveform recording device can be used to monitor the high-power, full-waveform voltages and currents of MTEM transmitters. It has high precision, finer edge details, low noise, and other advantages. Hence, it can be used for real-time recording and transmission to the receiver for coherent demodulation.

The widespread availability of low-cost electronics has created new opportunities for affordable geophysical equipment. Electromagnetic geophysical methods allow users to examine the electrical properties of the ground. The Colorado School of Mines electromagnetic system (CSM-EM) is a proof of concept instrument capable of sensing shallow conductive objects and costs under USD 400 to build. We tested the system in a laboratory setting and validated it over a metal target outdoors.

A fast Fourier transform was applied to fit the geomagnetic diurnal variation. Fitting results showed that when the polynomial degree was greater than 160, the residual error was close to 0 nT. White noise is the main component of the residual error when the polynomial degree was greater than 160, so this method was adopted to calculate the background noise of the geomagnetic field. Spectrum analysis further demonstrated the necessity to remove background noise from geomagnetic data.

Despite its importance to a range of applied and fundamental studies, and obvious parallels to a robust network of magnetic-field observatories, long-term geoelectric field monitoring is rarely performed. The installation of a new geoelectric monitoring system at the Boulder magnetic observatory of the US Geological Survey is summarized. Data from the system are expected, among other things, to be used for testing and validating algorithms for mapping North American geoelectric fields.

A numerical inversion approach to detect and localize inclusions in thick walls under quasi-periodic natural solicitations is presented. It is based on a preliminary analysis of surface temperature field evolution with time. This analysis is improved by taking advantage of a priori information provided by ground-penetrating radar reconstructions. In this way, it is possible to improve the accuracy of the images achievable with the stand-alone thermal reconstruction method.

In the field of marine controlled-source electromagnetic (MCSEM) systems, the evident issue of heating caused by the demand for high power was observed during previous marine experiments, where devices and cables were damaged due to overheating. Therefore, the idea was conceived to design a non-contact temperature measurement system tailored specifically to MCSEM systems, with the capacity to seamlessly adapt to the existing hardware conditions at sea.
