AIR-COUPLED FLEXURAL WAVES IN FLOATING ICE

Abstract

During a period of three weeks in February and March 1950, experimental studies of the propagation of elastic waves in floating ice sheets were made on Lake Superior and Lake Cayuga. These experiments were designed to study compressional, shear, flexural, and longitudinal surface waves in the ice- water system. In the course of the investigations an air-coupled flexural wave was discovered. Sufficient time remained to firmly establish the existence of this wave by performing additional tests. The experimental data obtained for air-coupled flexural waves and a brief summary of the theory are given in Part I of this report. A detailed theoretical investigation of these waves is presented in Part II.
