3D Forward Simulation of Borehole-Surface Transient Electromagnetic Based on Unstructured Finite Element Method

Minerals
The time-domain electromagnetic method has been widely applied in mineral exploration, oil, and gas fields in recent years. However, its response characteristics remain unclear, and there is an urgent need to study the response characteristics of the borehole-surface transient electromagnetic(BSTEM) field.

Evaluating the sustainability of mineral water consumption using multi‐scale hydrogeophysics in Caxambu, Brazil

Near Surface Geophysics, Volume 24, Issue 3, Page 234-251, June 2026.
Abstract A better understanding of the near‐surface aquifer system of the Caxambu Water Park, located in the Minas Gerais State, Brazil, has been achieved. The study aimed to identify groundwater reservoirs and flow patterns and contribute to the hydrogeological conceptual model using a multi‐scale geophysical approach.

Deciphering transitions within ice–debris complexes in the Northern Tien Shan through surface characteristics and internal structure

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Geophysical (GPR and ERT) data reveal a transition from buried glacial ice to an ice–debris mixture within ice–debris complexes in Kazakhstan; this transition is reflected in surface morphological and kinematic characteristics. We identify some relationships between internal ice content and associated surface kinematics but caution against ...

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

Journal of Field Robotics, Volume 43, Issue 3, Page 1646-1660, May 2026.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

A comprehensive monitoring of physico‐chemical properties of water by magnetization and impedance spectroscopy

River, Volume 5, Issue 2, Page 192-212, May 2026.
Abstract This study describes the effect of electromagnetic field (EMF) treatment on the chemical and electrical properties of tap water. It also contributes to a better understanding of the influence of this technique on the physicochemical properties of water exposed to different treatment times by an EMF generated by the Aqua 4D.
