Magnetic anomalies of the NW Iberian continental margin and the adjacent abyssal plains
Journal of Maps, 2020 The NW Iberian margin is a hyperextended continental margin, formed during the opening of the North Atlantic Ocean, where a subsequent partial tectonic inversion has undergone during the Alpine Orogeny. This succession of tectonic episodes determines the

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Ultra‐low‐frequency waves in the magnetosphere often produce field line resonances with strong spatial gradients in wave amplitude. We analyze a form of drift resonance driven by these gradients near the resonant field line. This mechanism differs fundamentally from conventional gradient‐ and curvature‐driven drift resonance and predicts an ...

Altitude Dependence of Quasi‐Static Potential Drop: The Effect of Ionospheric Protons
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Using an improved kinetic model that incorporates cold ionospheric protons and oxygen ions, we investigate the factors controlling the altitude range of the auroral acceleration region (AAR). In this model, parallel electric fields are generated via Dispersive Alfven Wave‐ Modified electron Acoustic Wave (DAW‐MEAW) coupling and sustained by ...

Space- and ground-based investigations of solar wind-magnetosphere-ionosphere coupling [PDF]
, 2006 This paper provides a brief review of the understanding of the coupled solar wind–magnetosphere–ionosphere system that can be attained from observations of the size of the ionospheric polar caps from space and the ground.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The upper thermosphere is important in the context of space weather, but continuous monitoring of the thermosphere at high latitudes remains limited despite its strong variations associated with geomagnetic activity. Orthohelium, He(23S), is found from the upper thermosphere to lower exosphere, and is a promising tracer of atmospheric dynamics.

Direct Observations of Reconnection Fronts in Earth's Turbulent Magnetosheath
The Astrophysical Journal, 2023 Reconnection fronts (RFs), ion-scale magnetic transients characterized by dramatic enhancement of reconnected magnetic fields, have been documented as crucial energy transfer regions during magnetic reconnection.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Along the flank magnetopause, magnetosheath flow interfaced with the relatively stationary magnetosphere produces strong flow shears, and the Kelvin‐Helmholtz instability (KHI) occurs. When the interplanetary magnetic field (IMF) is southward, anti‐parallel day‐side reconnection and KHI can interact, which may enhance the reconnection rate as ...

Saturation of Ionospheric Currents under Extreme Environments
The Astrophysical JournalStrong solar wind conditions can drive large electric potentials across planetary polar caps, but previous studies have shown that the cross polar cap potential reaches a saturation point during periods of high interplanetary magnetic field (IMF ...
