Regional character of geomagnetic field directional circularity: Holocene Eastern North America
Frontiers in Earth Science, 2023 This study characterizes the paleomagnetic secular variation (PSV) in five Holocene records from Eastern North America. We have determined equi-spaced (100-year) declination and inclination time series for the five sites and compared their directional ...

Dynamic mode decomposition of the geomagnetic field over the last two decades
Earth and Planetary Physics, 2023 Earth's magnetic field, which is generated in the liquid outer core through the dynamo action, undergoes changes on timescales of a few years to several million years, yet the underlying mechanisms responsible for the field variations remain to be ...

Secular variation of the geocenter [PDF]
Journal of Geophysical Research: Solid Earth, 2000 The degree 1 deformations of Earth induced by a surface load are computed, in a reference frame related to the center of mass of the planet, using a theoretical approach (Love number formalism), at secular timescale, where Earth has a viscoelastic behavior.

Geomagnetic Dipole Changes and Upwelling/Downwelling at the Top of the Earth's Core
Frontiers in Earth Science, 2018 The convective state of the top of Earth's outer core is still under debate. Conflicting evidence from seismology and geomagnetism provides arguments for and against a thick stably stratified layer below the core-mantle boundary.

Paleomagnatic Secular Variation (PSV) Swartvlei (South Africa)
, 2020 This is the first time that paleomagnetic secular variation data obtained from South African sediment records are used for dating purposes which is the only approach to establish a reliable chronology for recent sediments in this ...

Strong earthquakes and geomagnetic jerks: a cause-effect relationship?
Annals of Geophysics, 1995 Secular variation of the geomagnetic field observed at the Earth's surface has been found to undergo impulsive accelerations Gerks) lasting less than a few years. In this paper the relations between jerks and the occurrence of strong earthquakes (Ms ?
