Considerations on the Electrode-Spacing-to-Electrode-Diameter Ratio in Electrical Resistivity Tomography (ERT): An Operational Approach

IEEE Transactions on Instrumentation and Measurement
To develop small-scale, shallow, and high-resolution electrical resistivity surveys (e.g., for archaeological or agricultural purposes) the available literature highlights few requirements in terms of distance between two adjacent electrodes or electrode’s length embedded in the soil.

A Robust, Low‐Cost Conductance Sensor for High Resolution Real‐Time Monitoring of Streambed Pore Water Dynamics

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract The groundwater—surface‐water interface is an important regulator of many biogeochemical processes along river corridors. One of the main drivers of these processes is the pore water travel time along hyporheic flow paths. However, our understanding and ability to predict the spatial‐temporal dynamics of subsurface travel times are limited ...

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, Volume 68, Issue 4, Page 620-632, August 2026.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Challenges in the Detection of Water-Filled Cavities in Karst Environments Using Electrical Resistivity Tomography

Geosciences
Electrical resistivity tomography (ERT) is one of the most commonly used geophysical methods for imaging the distribution of electrical resistivity in the subsurface. It is often employed to characterise heterogeneity in karst regions and locate cavities

Depth‐Resolved Photo‐Degradation of Perovskite Layer in Solar Cells Stressed Under ISOS Light‐Aging Protocol Conditions: The Role of Substrate, Electron‐Transport‐Layer and Perovskite Deposition Method

Solar RRL, Volume 10, Issue 13, 15 July 2026.
Herein, a depth‐resolved analysis of ambient‐air‐processed perovskite layers employed in carbon‐based hole‐transport‐layer‐free photovoltaics subjected to ISOS light‐aging is provided. In all cases, the light‐induced degradation is demonstrated to start near both top and buried interfaces, and spread into the bulk, affecting perovskite crystals quality,
