The publication of these Proceedings of the Sixth U. S. 

 Navy Symposium on Military Oceanography provides a 

 valuable reference work for all who attended the Symposium. 

 For those who were unable to attend but who maintain a 

 strong interest in matters relating to oceanographic 

 technology, the theme of the 1969 Symposium, this volume 

 will also be very useful. 



Many fine papers submitted by some of the best people in 

 the oceanographic community could not be presented in 

 Seattle because of time restrictions. But we now have 

 access to these papers since these Proceedings contain 

 everything passed by the referee coiranittee. 



The Seattle Symposium was most successful and I would 

 again like to thank everyone who took time from their 

 busy schedules to attend. I would particularly like to 

 express my gratitude to Dr. Joseph E. Henderson and his 

 staff at the Applied Physics Laboratory of the University 

 of Washington for their superb organization of the three 

 day session, and to Dr. J. B. Hersey of the Office of 

 Naval Research for his excellent guidance as the General 

 Chairman of the 1969 Symposium.
