Abstract

A,bstract. The attenuation coefi%ient of ice in a temperate valley glacier was measured by spectral analysis of the pressure pulse, directly transmitted through the ice from a small explosion. Values varied from 0.014 ___ .002/m at 2.5 kc/s to 0.215 ___ .002/m at 15 kc/s. The attenuation function follows a form a ---A_ qB? closely, suggesting Rayleigh-type… (More)
