Depth Dependence of the Single and Triple Traversal Correlation Trace.

Abstract

Experimental evidence of the dependence on source depth of a particular correlation trace measured at near-bottom sensors in deep water is presented. The depth-dependent trace is produced by eigenrays having one and three ocean traversals, i.e., the direct path and the first bottom-bounce rays. A 65-95 Hz pseudo-random noise source towed at 100 m depth during the TAGEX87 experiment is used to examine the correlation trace for submerged sources, while the tow ship itself is used for surface sources. Ray model simulations accurately predict the change in the correlation traces as a function of source depth.
