FOREWORD 



This publication has resulted from a 2 1/2-hour lecture with the 

 same title that the author has presented as part of the Catholic University 

 of America summer graduate course in Ocean Acoustics under the directorship 

 of Dr. Frank A. Andrews. Its purpose is to introduce the vast subject of 

 oceanography in an elementary and compact way, emphasizing those features 

 that would be useful and interesting for acoustic applications. The 

 term "acoustic oceanography" as used here includes studies of the ocean 

 using acoustics as a tool. However, the extremely limited scope of the 

 lecture has led to the inclusion of only one or two acoustic examples 

 under each chapter heading.
