PHYSICAL PROPERTIES OF THE ICE ON FLETCHER'S ICE ISLAND (T-3)

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 Young&...

Description
Summary: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 Young's modulus and viscosity. It presents results of the examinations for vertical distribution of Young's modulus, viscosity, and density; sea-ice chlorine content measurements; and measurements of Young's modulus as a function of temperature. The viscous nature of land and sea ice and the activation energy are also discussed.
