Synopsis of an Investigation of the Acoustical Properties of Sea Ice.

Abstract

The goal of this research has been to determine the fundamental acoustical properties of sea ice. Our major accomplishment was measuring the temperature dependence, depth dependence, and anistropy of the propagation velocity of ultrasonic compressional wave pulses in sea ice cores. Additional work was done to examine methods for in situ measurement of compressional and shear wave velocity and attenuation of Arctic ice. Keywords: Compressional velocity; Penetrator; Ultrasonic properties; Anistropy.
