Pages : 74
Book Description
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.

Book Description
The acoustic properties of sea ice are inherently important to studies of sound propagation and scattering in the Arctic. The richness of the acoustic behavior of sea ice stems from its saline nature. In particular, sea ice is the result of the solidification of a sub-eutectic melt. This accounts for the high porosity layer at the ice/water interface, known as the skeletal layer. The high porosity makes measurements of the acoustic properties in the skeletal layer extremely sensitive to perturbations. Because this layer is a few centimeters thick, it is of primary importance for modeling the scattering of high frequency (above 10 kHz) acoustic energy from the underside of the ice.

Book Description
We made substantial progress in this contract contributing to new understandings of the acoustic properties of sea ice. We observed important dependences of acoustic properties of sea ice upon ice type and environmental conditions which was a result of our careful measurements of ice morphology that were concurrent with the acoustic measurements. As a result of our studies, we formulated semi-empirical acoustic models of the water/ice interface that can be used as input into scattering and propagation models. Keywords: Brines/porosity/desalination; Mathematical models; Acoustic waves; Acoustic reflection/attenuation. (edc).
