Laboratory Studies of Acoustic Scattering from the Underside of Sea Ice

Abstract

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.
