The electric field in northern England and southern Scotland: implications for geomagnetically induced currents. [PDF]
, 2006 Magnetotelluric (MT) data, in the form of MT tensors, are used to estimate directly the size and spatial distribution of the electric field in northern England and southern Scotland with the aim of predicting the flow of geomagnetically induced currents ...

A 100‐year Geoelectric Hazard Analysis for the U.S. High‐Voltage Power Grid
Space Weather, 2020 A once‐per‐century geoelectric hazard map is created for the U.S. high‐voltage power grid. A statistical extrapolation from 31 years of magnetic field measurements is made by identifying 84 geomagnetic storms with the Kp and Dst indices.

A comparison of methods for estimating the geoelectric field [PDF]
Space Weather, 2017 AbstractThe geoelectric field is the primary input used for estimation of geomagnetically induced currents (GICs) in conducting systems. We compare three methods for estimating the geoelectric field given the measured geomagnetic field at four locations in the U.S.

Investigating geoelectric tides at three geomagnetic observatories in the UK [PDF]
, 2020 Electric fields are generated in the Earth’s rocks and oceans by electromagnetic induction: for example through steady tidal motion of conducting sea water through the geomagnetic field or from the rapidly changing external magnetic fields in the ...
