Acoustic Sea Bed Reflectivity From a Submersible

Abstract

Acoustic bottom reflectivity measurements made from the submersible ALUMINAUT at two sites in the Caribbean show unusually low bottom losses compared to similar measurements made in the past from surface ships. The reason for these low losses is explored but no satisfactory theory can be postulated. The submersible technique is inherently superior to that usually deployed from a surface ship and removes many of the variables associated with a surface experiment. Further experimentation is required to develop the technique and confirm the low losses.
