Dielectric Properties of Deep Ice Cores with Air-Hydrate Inclusions (Abstract)

Abstract

Air-hydrate inclusions have been found in deep ice cores from Dye 3, Greenland, which were taken in August 1981 . Although the concentration of the air-hydrate crystals decreased with time, when the core was stored at a temperature of -50°C, they still existed to an appreciable extent in 1985.An ice specimen was cut out from the Dye 3 core at a depth of 1500 m, where the volume fraction of the hydrate crystals was about 10-3 by volume. Its dielectric ?10
