Abstract
Concentrations of the cosmogenic radioistopes /sup 36/Cl and /sup 10/Be have been measured in the top portion of the 1966 Camp Century deep ice core using tandem accelerator mass spectrometry. The primary motivations were to look for correlations with solar activity and to test the possibility that the ratio of /sup 10/Be to /sup 36/Cl would provide a means for dating old ice. An increase in each radioisotope is seen during the Maunder sunspot minimum (1650 to 1715 A.D.), as expected, but there are fluctuations of a factor of 2 or more over short time periods and a possible correlation with solar activity is apparent only when the data is mathematically smoothed. Variations of the /sup 10/Be//sup 36/Cl ratio by about a factor of five are observed which means that dating of ice by single /sup 10/Be//sup 36/Cl measurements covering the precipitation of only a few years will not be possible.
