Wide angle reflection studies at sea

Abstract

A self contained, free floating, recoverable sonobuoy system is described, for use in marine reflection and refraction surveys, together with a mathematical derivation of the wave amplitudes to be expected in such investigations. A detailed examination of the reflection and refraction results from several areas in the North Atlantic, obtained in the summers of 1973 and 1974 during the course of two Durham University Geophysical Surveys, is presented, in conjunction with simple processing procedures designed to extract information concerning the physical composition of the sea floor sediments, on the basis of the theory developed in the text.
