Foreword 



The increasing application of oceanography to naval opera- 

 tions, planning, and research is resulting in the dissemination 

 to the Fleet of many types of publications by this Office. The 

 i7itent of this glossary is to provide the users of our publications 

 with current basic definitions of the technical terms used therein 

 as an aid to the understanding, interpretation, and application 

 of the environmental data presented. Hopefully, others in the 

 oceanographic community will find this glossary helpful. 



To improve future editions of this publication, users are 

 urged to submit comments, suggestions, and pertinent material.
