Development of a Sea-Ice Thickness Gage. An Attempt to use Shear Waves.
Abstract
An experimental apparatus for the measurement of the thickness of sea-ice by the use of a shear wave reflection technique was designed and constructed. The apparatus was tested extensively in the Arctic during the summer of 1972. A portion of the apparatus, the horizontal impact source, produced reliable and repeatable excitation of the ice. Unfortunately, the measurement of the thickness of sea ice by the use of a shear wave reflection technique was not as simple as was anticipated, primarily due to the difficulty of properly exciting the ice and to the mode conversion of the acoustic energy by external and internal features of the ice.
