AC-ECM measurements of the Vestfonna ice core were carried out under the following conditions : at -12,-17,-22 and -27℃ under 1MHz; at -22℃ under frequencies from 300kHz to 1MHz. The relationship between conductance measured with AC-ECM and acidity was linear. It is considered that salt impurities a...
