Fluxes of the meteoric cosmogenic radionuclide 10 Be vary with changes in the incoming cosmic rays modulated by geomagnetic field intensity variations. The variability in the 10 Be flux can be used to synchronize ice cores, as well as marine sediments, by comparison with the relative paleointensity variations of the geomagnetic field. However, lock-in of the paleomagnetic signal at...
