Oscillating magnetic field disrupts magnetic orientation in Zebra finches, Taeniopygia guttata [PDF]

, 2009
Background Zebra finches can be trained to use the geomagnetic field as a directional cue for short distance orientation. The physical mechanisms underlying the primary processes of magnetoreception are, however, largely unknown.

Models of Present and Past Geomagnetic Core Field Evolution [PDF]

Journal Of The Geological Society Of India
ABSTRACT The main geomagnetic field originates in Earth’s outer core and shields our habitat against solar wind and cosmic radiation. Global descriptions of the field evolution are provided by data-based models. Such models are available for time spans from a few years to the past 100 kyr and some geomagnetic field polarity excursions ...

A Machine Learning‐Based Model of Three‐Dimensional Ion Fluxes in the High‐Altitude Earth's Northern Cusp

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Magnetic reconnection at the dayside magnetopause is the primary pathway for transferring mass, momentum, and energy from the solar wind into the terrestrial magnetosphere. Previous studies have shown that the spatiotemporal dynamics of dayside magnetic reconnection can be inferred remotely from properties of Earth's cusps, specifically their ...

Palaeosecular variations of the geomagnetic field in Africa during the Holocene: a review

, 2020
The importance of the full understanding of the Holocene geomagnetic field spans from human history and archaeology, to palaeoclimatic changes and engineering, to geomagnetic field modelling and unravelling of the geomagnetic field characteristics and ...

Ergodicity of the recent geomagnetic field [PDF]

, 2011
The geomagnetic field is a fundamental property of our planet: its study would allow us to understand those processes of Earth’s interior, which act in its outer core and produce the main field. Knowledge of whether the field is ergodic, i.e.

Dynamic Evolution of a Storm‐Time “Super‐EPB” Event Over China on the Magnetically Disturbed Night of 01 December 2023

Space Weather, Volume 24, Issue 10, October 2026.
Abstract This paper investigates the dynamic evolution of a storm‐time “Super‐EPB” event over China on 1 December 2023 (Kp ≤ 7, SYM/H ≥ −130 nT) using multi‐instrument observations. Occurring near sunset as the IMF‐Bz abruptly turned southward, with auroral extension to midlatitudes, the “Super‐EPB” extended to 40°N with an apex height of ∼2,460 km ...

Determination of a steady velocity field in a rotating frame of reference at the surface of the Earth's core [PDF]

, 1996
We relax the steady-motions theorem by solving for a steady velocity field at the surface of the core in a frame of reference drifting at a linear rate with respect to an observer fixed in the mantle frame of reference.

Assessing the Economic Benefits of Space Weather Mitigation Investment Decisions: Evidence From Aotearoa New Zealand

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Space weather events pose a growing threat to modern economies, yet their macroeconomic consequences remain underexplored. This study presents the first dedicated economic assessment of geomagnetic storm impacts on Aotearoa New Zealand, quantifying potential gross domestic product (GDP) losses across seven conservative disruption and ...
