A Comparison of ³⁶Cl Nuclear Bomb Inputs Deposited in Snow From Vostok and Talos Dome, Antarctica, Using the ³⁶Cl/Cl⁻ ratio

36 Cl production in the atmosphere is modulated by the magnetic field intensity of both the Sun and the Earth. The record of 36 Cl concentration along with that of 10 Be in ice cores may therefore provide information as to their variability. To better understand the 36 Cl signal in glaciological archives, we measured its concentration in Talos Dome snow samples (mean accumulation rate of 8 g cm −2 year −1 water equivalent) spanning the 1910 to...
