Acoustic Waves Incident on a Seawater/Sea Ice Interface.

Simple plane wave theory is used to compute the energies of reflected and transmitted elastic waves at a seawater/sea ice interface. The results indicate that for incident angles between 30 deg and 60 deg, most of the scattered energy is in the form of transmitted shear waves for typical values of s...

Description
Summary:Simple plane wave theory is used to compute the energies of reflected and transmitted elastic waves at a seawater/sea ice interface. The results indicate that for incident angles between 30 deg and 60 deg, most of the scattered energy is in the form of transmitted shear waves for typical values of sea ice and seawater densities and elastic wave velocities.
