Modelling the effects of space weather at the Earth’s surface : a UK geoelectric field model [PDF]
, 2004 Geomagnetically Induced Currents (GIC), which can flow in technological systems such as power transmission grids, are a consequence of the geoelectric field induced at the surface of the Earth during geomagnetic storms.

Sensitivity of the Geomagnetic Octupole to a Stably Stratified Layer in the Earth's Core
, 2018 Current "Earth-like" numerical dynamo simulations are able to reproduce many characteristics of the observed geomagnetic field. One notable exception is the geomagnetic octupolar component. Here we investigate whether a stably stratified layer at the top

Revised time-of-flight calculations for high-latitude geomagnetic pulsations using a realistic magnetospheric magnetic field model [PDF]
, 2005 We present a simple time-of-flight analysis of Alfvén pulsations standing on closed terrestrial magnetic field lines. The technique employed in this study in order to calculate the characteristic period of such oscillations builds upon earlier time-of ...

Journal of Quaternary Science, EarlyView.Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

New geomagnetic measurements in the Republic of Macedonia
Annals of Geophysics, 2013 This study presents measurements of the geomagnetic field of the Republic of Macedonia, performed through a network of newly defined repeat stations. The measurements of these elements were in the intervals of 3.378° ≤ DD ≤ 3.983°, 57.276° ≤ I ≤ 59.005°,

Ground geomagnetic field and GIC response to March 17, 2015, storm
Earth, Planets and Space, 2018 The St. Patrick’s Day geomagnetic storm on March 17, 2015, has been chosen by the space community for synergetic analysis to build a more comprehensive picture of the storm’s origin and evolution.
