Geomagnetic dipole moment and 10Be production rate intercalibration from authigenic 10Be/9Be for the last 1,3 Ma.
A synthesis of authigenic 10Be/9Be ratio records constructed from sedimentary sequences deposited over the last 300 ka in the North East Atlantic and over the 500-1300 ka BP interval in the West Equatorial Pacific Ocean is compared with proxies of the geomagnetic moment variations over the same time...
