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

Permafrost 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 ...

A deep geoelectrical survey in the Southern Central Alps

Annals of Geophysics, 1994
A deep geoelectrical survey was carried out on the Southern Central AIps, to the north of Bergamo, by means of the “continuous polar dipole-dipole” electrode array.

Superposed Epoch Analysis of Extreme Geomagnetic Disturbances at Auroral Zone Latitudes Over a Solar Cycle

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Intense and rapidly changing electrical currents in near‐Earth space produce geomagnetic disturbances (GMDs) with large magnetic field rates of change (dB/dt) and in turn large geomagnetically induced currents (GICs) in nearby power lines and pipelines. This study builds on the work of Engebretson, Yang, et al.

Geoelectric monitoring at the Boulder magnetic observatory [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2017
Despite its importance to a range of applied and fundamental studies, and obvious parallels to a robust network of magnetic-field observatories, long-term geoelectric field monitoring is rarely performed.

Groundwater Exploration in Aaba Residential Area of Akure, Nigeria [PDF]

, 2018
Groundwater plays a fundamental role in human life. Despite its indispensable characteristics, it is unfortunate that groundwater is often associated with low yield.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, Volume 55, Issue 2, Page 517-541, April 2026.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Geophysical assessment of subsurface conditions at proposed building sites: implications for foundation failure and building collapse [PDF]

, 2018
Building collapse has been a recurrent environmental hazard in Nigeria in the last two decades. This is a corollary of inadequate foundation investigation prior to construction, poor government policies, and general lack of awareness on the importance of

Time‐Domain Geoelectrical Modeling and Experimental Validation of Ground Potential Rise in Multilayer Soil Structures during Fault Events

Energy Science &Engineering, Volume 14, Issue 3, Page 1492-1504, March 2026.
This study develops a time‐domain geoelectrical model of ground potential rise (GPR) in multilayer soil that couples electromagnetic field theory with nonlinear fault arc resistance. Finite‐element simulations calibrated against scaled fault‐injection experiments reproduce measured GPR and step/touch voltages within 4.7% error, revealing that steady ...
