Abstract

Firn from an ice cave in the highest mountain of Greece, Mt. Olympos, was sampled and analysed to determine the tritium content in order to estimate rates of accumulation and to date the ice plug. The presence of a sharp raise of tritium content because of the nuclear testing era was expected to be preserved into ice beds. This peak did not appear in the analysed samples providing an age estimation of less than 50 years. It is suggested that the rate of melting is responsible for the absence of older firn layers.
