Abstract
The thousand years old cave ice records information about the Late Holocene environmental changes. Isotope studies are proxies to reveal frozen information. Using 3H-3He and radiocarbon methods few individual ice layers were dated. Furthermore, short term (2.7 cm/yr) and long-term (0.79-0.9 cm/yr) growth rates were calculated. The two growth rates show a ratio of ca. 3 : 1. Identifying the strata of impurities the different ice producing periods are separated. So the delta-18O curve of the ice core, which can represent maximum 850+/-50 years long duration, is divided into intervals according to freezing age.
