Abstract Subglacial sedimentary basins in Antarctica are hypothesized to modulate ice flow and biogeochemical cycles via groundwater and geothermal feedbacks, yet their properties remain poorly constrained. Here, we present a joint quantitative analysis of new magnetotelluric (MT) data acquired at Thwaites Glacier (TG) and WAIS Divide, alongside legacy

Abstract The complex conductivity method, also known as spectral induced polarization (SIP), is widely used in hydrogeophysical investigations. Power‐law functions with positive exponents between the in‐phase/quadrature components of complex conductivity and water saturation are key petrophysical relationships to interpret field data.

Abstract The spatial association between electrical conductors and ore deposits underpins the widespread use of magnetotellurics (MT) in mineral exploration, yet not all mineral systems preserve a diagnostic conductive signature. Here, we present a high‐resolution MT study of the region hosting the world‐class Broken Hill Pb‐Zn‐Ag deposit (NSW ...

A resistivity meter can find out resistivity depth of rock structure, sediment layer, or the depth of water surface. However, the resistivity meter that is often used requires manually recording of the measurement results before inputting them into the ...

Geoelectric determination of quality changes and tectonic disturbances in coal deposits
A new underground geoelectric method is presented for the determination of small tectonic disturbances and barrenings in coal seams. The distribution of the apparent resistivity can be mapped from the measured apparent resistance data by using a ...

Space Weather Mitigation Decisions by Critical Infrastructure Operators During Solar Cycle 25
Abstract The “Gannon Storm” in May 2024 was the largest space weather event experienced in 20 years, generating auroras at latitudes as low as 35°, visible in Florida and Mexico. Such events pose significant operational challenges for critical infrastructure operators, particularly those managing electricity transmission networks, satellite ...

Parameter sensitivity maps of surface geoelectric arrays [PDF]
Parameter sensitivity maps allow a better understanding of various geoelectric responses, and they are also helpful in designing optimal new arrays for specific problems. We constructed systematic parameter sensitivity maps for various geoelectric arrays,
