The electrical conductivity of natural ice samples is strongly correlated with the acidity of the melted sample and can therefore be used for climatological studies. Two physical aspects concerning this conductivity measurement have been investigated. For the used setup with unguarded electrodes it could be shown that volume conduction dominates surface conduction at -15 ⁰C. A relation between the measured conductance and the specific conductivity is established. The aging observed on stored ice samples is shown to be strongly dependent on the composition of the gas in which the ice samples are stored. Ammonia diffuses rapidly into the ice and changes its conductivity.
