Isotopes produced by the interaction of galactic cosmic rays (GCRs) with atmospheric gases are incorporated in ice, sediments and plants. Beryllium-10 (10Be) has a half life (t1/2) of 1.5 Myr. Its short atmospheric residence time means that changes in 10Be production can be traced at high resolution in stratified ice, but extracting the solar signal is complicated by climatic, geomagnetic and other factors and is performed confidently only for data from ~100–1,000 yr BP, where the Maunder and… CONTINUE READING
