Universal Time variations in the magnetosphere

Frontiers in Astronomy and Space Sciences, 2023
We study the dependencies of Earth’s magnetosphere on Universal Time, UT. These are introduced because Earth’s magnetic axis is not aligned with the rotational axis and complicated because it is eccentric, which makes the offset of the magnetic and ...

Correlation‐based modeling and separation of geomagnetic field components [PDF]

Journal of Geophysical Research: Solid Earth, 2016
AbstractWe introduce a technique for the modeling and separation of geomagnetic field components that is based on an analysis of their correlation structures alone. The inversion is based on a Bayesian formulation, which allows the computation of uncertainties.

Geomagnetic Intensity of Hellenistic Pottery and Stamped Rhodian Wine Amphorae From Jerusalem

Archaeometry, EarlyView.
ABSTRACT Stamped amphora handles produced on Rhodes during the Hellenistic period are well suited for archaeointensity studies because they often bear the names of annually appointed magistrates (eponyms) and fabricants, allowing dating to narrow time intervals.

Predictability of Magnetic Field Reversals

Mathematics
Geomagnetic field measurements indicate that at present we may be on the brink of the Earth’s magnetic field reversal, potentially resulting in all the accompanying negative consequences for the mankind.

Izbira lokacije za postavitev geomagnetnega observatorija v Sloveniji : Site selection for a permanent geomagnetic observation station in Slovenia [PDF]

Geodetski Vestnik, 2010
Raziskave na področju geomagnetizma lahko označimo kot prve raziskave na področju geofizike. Opazovanje geomagnetnega polja je bistvenegapomena za razumevanje temeljnih postopkov v središču Zemlje, njeni skorji in bližnji okolici planeta Zemlja.

Methodology for simulation of geomagnetically induced currents in power systems

Journal of Space Weather and Space Climate, 2014
To assess the geomagnetic hazard to power systems it is useful to be able to simulate the geomagnetically induced currents (GIC) that are produced during major geomagnetic disturbances.

Evaluating the applicability of the finite element method for modelling of geoelectric fields [PDF]

Annales Geophysicae, 2013
Geomagnetically induced currents in power systems are due to space weather events which create geomagnetic disturbances accompanied by electric fields at the surface of the Earth.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

High-latitude ionospheric currents during very quiet times: their characteristics and predictability [PDF]

Annales Geophysicae, 2004
CHAMP passes the geographic poles at a distance of 2.7° in latitude, thus providing a large number of magnetic readings of the dynamic auroral regions.

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...
