A Rapid Geophysical Technique for Subbottom Imaging

Abstract

This technical note describes the low-noise, high-resolution subbottom imaging system developed to remotely and efficiently determine characteristics of subbottom marine sediments as they relate to dredging The theoretical foundation of this approach, which is based on acoustic impedance, is described. A case history survey of Galveston Ship Channel is also summarized.
