Geoelectrical soundings in Holsteinsborg

Rapport Grønlands Geologiske Undersøgelse, 1971
In the summer of 1969 a geoelectrical sounding programme was started in Holsteinsborg by the second author with equipment borrowed from the Institute for Applied Geology, the Technicai University of Denmark. The folIowing summer the work was followed up by further soundings at selected localities in the same area based on the results from the first ...

REPRODUCING OPERATIONAL LANDSCAPES: The Rock Mining for Indonesia's New Capital City

International Journal of Urban and Regional Research, EarlyView.
Abstract Indonesia's new capital city is designed to become a green and sustainable city. In this article, we examine the (un)sustainability of the process through which the city is coming into being. Using the sociospatial theory of planetary urbanization, we trace the dialectical relationship between the new city and sites beyond it to show how ...

On the Geoelectrical Characterization of an Old Landfill Cover [PDF]

Proceedings, 2011
Two geoelectrical methods were used to characterize the state of an old French landfill cover. The objectives were to locate different materials used for the covering such as clay material or geomembrane and to identify heterogeneities that could be linked to possible defects in the cover due to fractures or cracks.

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

2D inversion processing of geoelectric measurements with archaeological aim

, 2012
The paper presents the opportunities of archaeological applications of the geoelectric geophysical methods. The electrical conductivity properties of buried archaeological objects (wall relics, roads, channels, graves, metal objects, etc.) measurably ...

Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Multiphysics Monitoring of Capillary, Electrical, and Elastic Responses During Drainage and Imbibition at Reservoir Conditions

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Capillary pressure‐saturation relationships are crucial for geo‐energy recovery, and increasingly, for environmental applications. However, for reservoir‐relevant pressure and temperature conditions, only limited data sets are available from special core analysis in laboratory (SCAL) studies.

An Approximate Time‐Domain Solution for Recharge Propagation Through Thick Unsaturated Zones

Hydrological Processes, Volume 40, Issue 6, June 2026.
This study presents a time‐domain analytical solution for modelling groundwater recharge through thick unsaturated zones, applied to the Urucuia aquifer in Brazil. The model was calibrated using observed well data, capturing the attenuation of seasonal groundwater level fluctuations with depth.

Geoelectrical Signatures of Redox Processes [PDF]

81st EAGE Conference and Exhibition 2019, 2019
Summary Common redox potential sensors provide point measurements and are error prone. Destructive sampling can cause contact with air which will influence the redox state. Hence, assessing redox conditions in soil is challenging. Redox sensitive reactions like the degradation of organic contaminants will change water chemistry and geophysical ...

The United States Magnetotelluric Array and the National Impedance Map

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.
