Abstract:

During the period Sep 1959-Feb 1960, studies were made of the visco-elastic properties of land- and sea-ice samples taken from 12 sites on T-3. Also, crystallographic investigations were made of the samples, using a polarizing microscope. This report describes the sonic method used to measure Youngs modulus and viscosity. It presents results of the examinations for vertical distribution of Youngs modulus, viscosity, and density sea-ice chlorine content measurements and measurements of Youngs modulus as a function of temperature. The viscous nature of land and sea ice and the activation energy are also discussed.
