Journal of Environmental & Engineering Geophysics (JEEG)

Park Seismic's ParkSEIS Mount Sopris Instruments Geometrics' Geode EM3D Advanced Geosciences, Inc. SAGA Geophysics, Inc. A Forward by the Editor Since taking over JEEG in late 2016, we on the editorial board have pushed 141 unique and novel articles to publication, spread over 13 issues. Publishing all of these papers has been a lot of work, but well worth the effort because of the cutting edge science the authors share with all of us. I have the particular advantage of advanced previews of these works before they hit the shelf. Interestingly, of these papers, the geophysical method by far published the most is electromagnetics (EM) and I talked at length about the large number of papers for this method in a previous editorial. EM has a dedicated special issue to its use on airborne platforms, published in March 2017, and an EM paper or two can be found in just about other every issue that is not already dedicated to another method.

The next set of methods with high attention, with 25, 26, and 27 papers, include ground penetrating radar (GPR), seismic, and resistivity & induced polarization, respectively; each have roughly half of those dedicated to EM. The final methods with minimal attention include gravity, nondestructive testing (NDT), borehole geophysics, NMR, TDR, and SP.

While many of the papers published in JEEG have enjoyed great fame (e.g., Diamanti et al., 2017; Vignoli et al., 2017), there are others that have not received the attention they deserve. I judge this by the number of citations to date, which can easily be investigated on Google Scholar. For example, some great EM papers include those by Cabuk et al. (2017), where a DIY project included building a VLF receiver, and Liu et al. (2018), who developed a rapid and stable inversion model for controlled-source EM in the frequency domain. Li et al., (2018) used EM to help solve a famously difficult and important question with regards to CO2 injection monitoring. Continuing with the electrical theme, Crook and Rucker (2017) conducted a marine resistivity survey of the Mono Lake in California, where subsurface structure could be identified despite the hypersaline conditions of the water. There also has been significant advancements in measuring the dielectric permittivity, either through GPR or TDR. These include the work by D´erobert et al. (2018), who investigated concrete degradation and carbonation, Garner and Coffman (2016) who used a single polarization, vertical wave propagation (transmitted-vertical wave propagation received (VV) configuration) GPR as instrumented in the Gamma Remote Sensing Portable Radar Interferometer version II (GPRI-II) for soil moisture measurements, and Persico et al. (2018) who investigated coaxial cable usage for TDRs. Tanajewski et al. (2018) investigated the potential interference of high frequency GPS data as a contributor to noise on GPR. Seismically, Liao et al.  (2018) used a novel filter approach for 3D terrestrial seismic data and Zhang et al. (2017) used optimization for seismic modeling based on the random movements of fruit flies. And finally, there have been a few excellent papers on combined geophysical methods, such as that presented in Fabien-Ouellet et al. (2017) and Feng et al. (2018).
