Scale Model Ultrasonic Study of Arctic Ice.

Abstract

The work sponsored by this Contract was concerned with a scale-model study of sonic reflectivity, transmissivity and the partition of energy upon sonic incidence at the Arctic Ice cover. The basic experimentation was accomplished by using megahertz ultrasonic signals and allowing them to impinge, in a controlled manner, on various liquid/solid boundaries, simulating as much as feasible the actual situation which is found in the Arctic. From the results of the measurements of reflectivity and mode conversions on scale-model samples, a number of properties of both the liquid and the solid were deduced.
