Two Records of Relative Paleointensity for the Past 4 Myr
Frontiers in Earth Science, 2020 We performed new high-resolution magnetic measurements of sedimentary cores from the east northern Pacific ODP Site 1021 and the East equatorial Pacific ODP Site 851.

Impact Plasma Amplification of the Ancient Mercury Magnetic Field
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)

Holocene Paleointensity of the Island of Hawai `i From Glassy Volcanics
Geochemistry, Geophysics, Geosystems, 2018 This study presents new high‐quality paleointensity records and 14C radiocarbon age determinations from the Island of Hawai `i during the Holocene. Previous studies on Hawai `i use experimental methods and statistical selection criteria that may produce ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract We present a new method for paleomagnetic investigations, polarized neutron imaging, a non‐destructive magnetic imaging technique benefiting from the high penetration depth and spin of the neutron allowing spatial characterization of the magnetic field within a sample.

Geochemistry, Geophysics, Geosystems, 2023 The natural remanent magnetization (NRM) of high sedimentation rate sediments provides significant information about paleomagnetic secular variation of the Earth's magnetic field and can also potentially be used for stratigraphy. However, NRM acquisition

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...

Controlled-atmosphere thermal demagnetization and paleointensity analyses of extraterrestrial rocks [PDF]
, 2013 We describe a system for conducting thermal demagnetization of extraterrestrial rocks in a controlled atmosphere appropriate for a wide range of oxygen fugacities within the stability domain of iron.
