Design Features of the Submersible Modular Acoustic System

The submersible modular acoustic system is a general-purpose acoustic measurement intended for use on the submersible ALVIN. It is presently nearing completion. This report gives a description of the system and its components to serve as an aid in designing experiments and to provide the instrumental basis for a series of experiments to be discussed in later reports. Other acoustic items which are available for use on ALVIN are listed, as are other submersible instruments which might profitably be used with this acoustic tool.
