Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 2, Page 267-283, April/June 2026.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Time‐Varying Gravity Constraints on Groundwater Recharge and Managed Aquifer Strategies in Southern Taiwan

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Understanding groundwater recharge pathways is essential for designing effective managed aquifer strategies, yet in heterogeneous alluvial aquifers, these pathways are often uncertain and difficult to resolve with sparse well networks. We apply gravity as an independent constraint to quantify groundwater storage dynamics and evaluate recharge ...

The Evolving Roles of Electrical Geophysical Methods for In Situ Remediation Assessment: Progress and Perspectives

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract In situ remediation of contaminated soil and groundwater demands real‐time monitoring to capture complex subsurface dynamics. Geophysical methods, particularly electrical resistivity tomography (ERT) and induced polarization (IP), offer non‐ or minimally invasive, high‐resolution imaging of subsurface changes during remediation.

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

open access: yesBoreas, Volume 55, Issue 2, Page 476-502, April 2026.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Groundwater Temperature Processes and Patterns: Implications for Stream Thermal Regimes

open access: yesWIREs Water, Volume 13, Issue 2, March/April 2026.
Shallow groundwater temperatures are controlled by ground surface temperatures and are influenced by climate change and land cover changes. Deeper groundwater temperature is constant year‐round, making it cooler (warmer) in the summer (winter) than surface water, and exhibits a lagged response to surface warming.

Comparison of novel semi-airborne electromagnetic data with multi-scale geophysical, petrophysical and geological data from Schleiz, Germany [PDF]

open access: yes, 2020
In the framework of the Deep Electromagnetic Sounding for Mineral EXploration (DESMEX) project, we carried out multiple geophysical surveys from regional to local scales in a former mining area in the state of Thuringia, Germany.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Broadband Dielectric Analysis of Clays: Impact of Cation Exchange Capacity, Water Content, and Porosity

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Clay‐rich soils and sediments are key components of near‐surface systems, influencing water retention, ion exchange, and structural stability. Their complex dielectric response under moist conditions arises from surface–ion electrostatics and diffuse double layers that govern transport and retention processes. This study explores the broadband

Stochastic inversion of transient electromagnetic data to derive aquifer geometry and associated uncertainties [PDF]

open access: yes
Understanding processes in the Critical Zone requires reliable information about the vadose-zone aquifer, its geometry, and spatial variability. Commonly, such information is obtained from boreholes, yet large areas might render their application ...
