Predicting the movements of permanently installed electrodes on an active landslide using time-lapse geoelectrical resistivity data only [PDF]

open access: yes, 2010
If electrodes move during geoelectrical resistivity monitoring and their new positions are not incorporated in the inversion, then the resulting tomographic images exhibit artefacts that can obscure genuine time-lapse resistivity changes in the ...

Resisting Potato Cyst Nematodes With Resistance [PDF]

open access: yesFrontiers in Plant Science, 2021
Potato cyst nematodes (PCN) are economically important pests with a worldwide distribution in all temperate regions where potatoes are grown. Because above ground symptoms are non-specific, and detection of cysts in the soil is determined by the intensity of sampling, infestations are frequently spread before they are recognised.

Monitoring the bio-self-healing performance of cement mortar incubated within soil and water using electrical resistivity [PDF]

open access: yes, 2023
In research on self-healing concrete, the restorative performance can be evaluated by a wide range of techniques. However, most of these techniques can be challenging to apply to concrete samples embedded in soil without causing a significant disturbance

Evidence for Pathways of Concentrated Submarine Groundwater Discharge in East Antarctica from Helicopter-Borne Electrical Resistivity Measurements

open access: yesHydrology, 2019
The Southern Ocean receives limited liquid surface water input from the Antarctic continent. It has been speculated, however, that significant liquid water may flow from beneath the Antarctic Ice Sheet, and that this subglacial flow carries that water ...
