Multi-dimensional Inversion Modeling of Surface Nuclear Magnetic Resonance (SNMR) Data for Groundwater Exploration [PDF]

open access: yes, 2014
Groundwater is an important economic source of water supply for drinking water and irrigation water for agriculture. Surface nuclear magnetic resonance (SNMR) sounding is a relatively new geophysical method that can be used to determine the presence of ...

Electromagnetic studies of Zvizdal-Zaliska and Brusyliv fault zones of the Ukrainian shield

open access: yesГеофизический журнал, 2019
Spatial-temporal distribution pattern of geomagnetic variations and electric field in the western part of the Ukrainian shield has been obtained as a result of experimental studies carried out by the methods of deep magnetotelluric sounding and ...

Magnetotelluric and geomagnetic depth soundings around the Torres Syncline Hinge, southeast Paraná Basin, Brazil [PDF]

open access: yesGeophysical Research Letters, 2000
A MT/GDS survey has been carried out around the NW plunging Torres Syncline in the southeastern border of the Paraná Basin, in Brazil. Induction arrows show a NW‐trending conductive anomaly nearly coincident with the hinge of the syncline and ocean effects varying as a function of the distance from the coast.

Evidence of Bermuda Hot and Wet Upwelling From Novel Three‐Dimensional Global Mantle Electrical Conductivity Image

open access: yesGeochemistry, Geophysics, Geosystems, 2020
A model of electrical conductivity in the mid–mantle transition zone was obtained with improved constraints. An L1‐norm regularization inversion algorithm is proposed here that reduces the influence of noisy data on three‐dimensional geomagnetic depth ...

Fish welfare in a changing world: New developments and current challenges

open access: yesJournal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Melting in the crust and upper mantle beneath the Kenya Rift: evidence from Geomagnetic Deep Sounding experiments [PDF]

open access: yes, 1979
A Geomagnetic Deep Sounding experiment in and around the Kenya Rift Valley has shown that telluric currents are concentrated by 3 regions with high electrical conductivity.

Geomagnetic depth sounding over the Singhbhum and the surrounding regions of eastern India

open access: yesJournal of Earth System Science, 1994
Magnetovariational studies have been carried out in Singhbhum and surrounding regions during 1987 and 1989. Three deep-seated linear conductors have been identified. One of them is located to the north of Ranchi, Bokaro and Purulia extending in E-W direction coinciding with high heat flow region and Gondwana sediments.

Loess Studies in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.
