36Cl studies at the ETH/SIN-AMS facility
Abstract
36Cl has been measured in polar ice from Dye 3 (65° 11 N, 43° 50 W) and Camp Century (77° 11 N, 82° 08W) in Greenland. In an exploratory study 4 series consisting of about 20 samples each have been selected covering approximately the following time periods: 12000-10000 BP (transition Wisconsin-Holocene), 1530-1730 A.D. (Maunder minimum), 1942-1977 A.D. (nuclear bomb pulse) and 1978 (seasonal variations). The results are compared with 10Be data of the same cores which were measured previously. The variations of the {10Be }/{36Cl } ratio are generally larger than expected from the experimental errors indicating that this ratio is not suitable for dating of old ice.
