Abstract

In a very short period of time, 10Be data have significantly improved our knowledge in various fields of Earth and planetary sciences. Examples are: (a) solar modulation of isotope production, revealed in 10Be ice-core profiles; (b) geomagnetic modulation of isotope production, revealed in 10Be ice-core (from the past 10 ka) and ocean-sediment profiles (geomagnetic reversals); (c) climatic effects reflected in 10Be profiles in loess and polar ice cores (10Be behaviour in atmosphere); (d) comparison of 10Be and 14C variations (tree rings) from carbon-cycle models and information on ocean circulation history from 14C measurements on benthic and planktonic Foraminifera in ocean sediments. An overview on work in collaboration with the Zurich AMS facility (with Professor W. Wolfli) is given.
