A paleointensity test of the Geocentric Axial Dipole (GAD) hypothesis [PDF]

, 2017
The Geocentric Axial Dipole (GAD) model is central to many aspects of geophysics, including plate tectonics and paleoclimate. But its validity is by no means firmly established, particularly for the Precambrian.

A geomagnetic paleointensity stack between 0.8 and 3.0 Ma from equatorial Pacific sediment cores

, 2005
We have conducted a paleomagnetic study of six sediment cores taken from the equatorial Pacific, three from the West Caroline Basin and three from the Manihiki Plateau, in order to make a relative paleointensity stack during the Matuyama and late Gauss ...

Paleomagnetic Secular Variation Records From the Post‐Glacial Tahiti Coral Reef

Earth and Space Science
IODP Expedition 310 recovered more than 600 m of Post Last‐Glacial‐Maximum (LGM) coral reef framework rocks from the current reef tract surrounding the island of Tahiti. Six sites (12 holes) were sampled for paleomagnetic studies on the south side of the
