We present in this study a 10Be profile from a deep-sea sediment section extending to 3.5 Ma. The 10Be concentration ranges at 2-14 × 108 atoms/g and shows a clear decay trend. The flux of 10Be ranges at 1-5 × 106 atoms/cm2 y and averages at ≈ 2.5 × 106 atoms/cm2 y. Enhancements in the 10Be record occur at the paleomagnetic reversals and excursions suggesting strong effect of changes in the geomagnetic field intensity. Indication of climatic-related variability is also observed from the generally higher 10Be values during interglacial compared to glacial periods.
