Bayesian Inference of Local Paleosecular Variation from Sparse Paleomagnetic Data
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.We introduce a novel Bayesian method to construct local paleosecular variation (PSV) curves. By modeling the geomagnetic field as a Gaussian process, global models can be incorporated as informative prior distributions.

Assessing Paleosecular Variation Averaging and Correcting Paleomagnetic Inclination Shallowing
Journal of Geophysical Research: Solid EarthAbstractThis paper addresses one of the critical questions of scientific inquiry: How do we know when a given data set is representative of the phenomenon being examined? For paleomagnetists, the question is often whether a particular data set sufficiently averaged paleosecular variation (PSV).

Palaeomagnetism of the Upper Miocene- Lower Pliocene lavas from the East Carpathians: contribution to the paleosecular variation of geomagnetic field. [PDF]
Sci Rep, 2016 Investigations of the paleosecular variation of the geomagnetic field on geological timescales depend on globally distributed data sets from lava flows. We report new paleomagnetic results from lava flows of the East Carpathian Mountains (23.6°E, 46.4°N)

Geophysical insights from the first geomagnetic field absolute intensity curve for central Asia (2200BCE–2000CE), and implications for archaeomagnetic dating [PDF]
Scientific ReportsUntil now, the lack of high-quality paleointensity data has left Central Asia as a major gap in global and regional reconstructions of geomagnetic field intensity variations.

Journal of Geophysical Research: Solid Earth, 2021 A full‐vector paleosecular variation (PSV) record (inclination, declination, and relative paleointensity) from the pen‐ultimate glacial (130–180 ka) could be constructed from a total of 12 sediment cores recovered from the Arkhangelsky Ridge in the SE ...

Long-term persistency of a strong non-dipole field in the South Atlantic [PDF]
Nature CommunicationsEarth’s magnetic field exhibits a dominant dipole morphology. Notwithstanding, significant deviations from the dipole are evident today, particularly the South Atlantic Anomaly (SAA), characterized by anomalously low-field intensity and high directional ...
