3D effects of seawater on electrical resistivity tomography near shorelines—Challenges and possible solutions inferred from synthetic and field data

Near Surface Geophysics, Volume 24, Issue 4, Page 364-391, August 2026.
Abstract Electrical resistivity tomography (ERT) is one of the most widely used geophysical techniques for hydrogeological questions, such as investigating the groundwater transition zone between land and sea. The interpretation of 2D coast‐parallel ERT profiles is challenging because most of the electrical current flows through the highly conductive ...

Control System for the Navigation of the Agricultural Robots: A Review

Journal of Field Robotics, Volume 43, Issue 5, Page 3474-3505, August 2026.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Empirical Assessment of Storm‐Time Thermospheric Density Inversion Methods From LEO POD Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Thermospheric mass density is one of the largest sources of operational uncertainty for spacecraft in low Earth orbit, particularly during geomagnetic storms. The growing population of Global Navigation Satellite System‐equipped satellites presents a data set of opportunity: precise orbit determination (POD) data streams can be used to ...

On the Generation of Pre‐Sunrise Equatorial Plasma Bubbles in Southeast Asia During the Geomagnetic Storm of May 2024

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract A set of fresh Equatorial Plasma Bubbles (EPBs) formed during pre‐sunrise hours in the Southeast Asian sector amid the recovery phase of May 2024 geomagnetic storm. They offered new insights into their formation mechanism. This study used Total Electron Content (TEC) and Rate of TEC Index maps over Indonesia, along with ionosondes in Thailand ...

Increasing Frequency of Coastal Erosion Indicated by a Hindcast Model of Storm‐Driven Forcing Calibrated With Beach Stratigraphy

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Beach stratigraphy at North Beach, Sandy Hook, New Jersey is used to calibrate a model of coastal erosion, establish a model‐based erosion threshold, and evaluate how often threshold conditions have been exceeded since 1979 through hindcast analysis.
