Paleomagnetic and beryllium isotope record of West Equatorial Pacific sediments, supplement to: Carcaillet, Julien; Thouveny, Nicolas; Bourlès, Didier L (2003): Geomagnetic moment instability between 0.6 and 1.3 Ma from cosmonuclide evidence. Geophysical Research Letters, 30(15), 1792

The reliability of paleomagnetic records as proxies of the geomagnetic field intensity is still a matter of controversy since volcanic materials hardly provide continuous records, and marine sediments are suspected to carry a remanence biased by post-depositional realignments and/or by overprints. Such long standing debate emphasizes the need for the development of methods independent from paleomagnetism to decipher geomagnetic intensity variations. High resolution measurements of authigenic 10Be/9Be along with a detailed sedimentary record of directional...
