Testing the Accuracy of Paleointensity Estimates Using Experimental Pottery Assemblages

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Paleointensity estimates from archaeological pottery represent a key source of information on Holocene variations in geomagnetic field intensity. Yet, pottery rarely exhibits ideal single‐domain behavior that fully satisfies the theoretical assumptions underlying absolute paleointensity methods.

A relative paleointensity record of the geomagnetic field since 1.6 Ma from the North Pacific [PDF]

open access: yes, 2007
A paleomagnetic study was conducted on a sediment core KR0310-PC1 taken from the central North Pacific in order to obtain a relative paleointensity record in the Matuyama chron from this region. The core reached to about 1.6 Ma.

Variations of the geomagnetic field during the Holocene: Relative paleointensity and inclination record from the West Pacific (ODP Hole 1202B)

open access: yes, 2006
We conducted detailed rock magnetic investigations on 36m of drill core collected during Ocean Drilling Program Leg 195 at Hole 1202B (24◦48.24 N, 122◦30.00 E), in the Southern Okinawa Trough, with the goal of extracting a reliable paleointensity signal

Archeointensity Database and Geomagnetic Field Reference Curves for South America Over the Past 5 Millennia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The study of variations in geomagnetic field intensity over time and space is crucial to understand the evolution of the geodynamo and its interactions with the Earth's surface. In this work, we introduce the SAGEOMAG (South America GEOMAGnetic) database, a comprehensive and updated repository of geomagnetic field intensity records derived ...

Distance‐Dependent Stray Field Decay in Magnetically Stable Remanence Carriers: Implications for Magnetic Microscopy

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Micropaleomagnetic analysis offers a path to high‐precision reconstructions of ancient magnetic fields from terrestrial and space‐returned samples by inverting the vertical stray field of individual particles to recover their magnetic moments through the use of magnetic microscopes.

Evidence for Missing Geomagnetic Reversals From Geomagnetic Reversal Frequency Model Using Adaptive Kernel Density Estimation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The existence of missing geomagnetic reversals has been proposed, with potential for new magnetostratigraphic age controls. We estimate geomagnetic reversal frequency from 0 to 155 Ma using adaptive‐bandwidth kernel density estimation (AKDE) to evaluate data sparseness and to assess how reversal frequency changes when recently identified ...

Reconstructing Late Pleistocene to Prehistorical Holocene Geomagnetic Field Variations From La Palma Lava Flows (Canary Islands, Spain): Unraveling Viscous Components

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present new vector paleomagnetic data from 13 radiometrically dated lava‐flows in southern La Palma (Canary Islands) spanning from 1 to 56 ka, which covers most of the Late Pleistocene to prehistoric Holocene volcanic record in the island.

Paleomagnetic data (inclination, declination, relative paleointensity) in sediment core AMD1902-10GC from Petermann Fjord (Nares Strait, Northern Greenland)

open access: yes
This dataset contains paleomagnetic data (inclination, declination, relative paleointensity) of core AMD1902-10GC. This core was collected in Petermann Fjord (Nares Strait, Greenland, Arctic) during Leg 2 of the 2019 ArcticNet Expedition on board the ...
