  • Abstract
    The results of experimental investigations of reflection, scattering and absorption of ultrasound by sea ice are discussed. A theoretical review of the absorption of sound waves in the body of young sea ice on the basis of suggested double component model is given. It is shown that the absorption in such ice is due to the viscous friction of brine in ice pores. The experimentally obtained angular relationships of ultrasound scattering by ice cover in case the sound is sent through the water are discussed.
