10 Be in the Akademii Nauk ice core – first results for CE 1590–1950 and implications for future chronology validation

ABSTRACT Temporal variations of the radionuclide 10 Be are broadly synchronous across the globe and thus provide a powerful tool to synchronize ice core chronologies from different locations. We compared the 10 Be record of the Akademii Nauk (AN) ice core (Russian Arctic) for the time period CE 1590...
