giving tlie authoritative source of a defi- 

 nition and 2) giving sources from which 

 a review of a specific subject can be 

 made. Where the definition given re- 

 flects substantially that given in the 

 source, a number in parentheses corre- 

 sponding to that item in the List of 

 Sources follows the definition. If a 

 term has multiple definitions, the loca- 

 tion of the source number underneath 

 the entry on the left indicates that this 

 source supports all definitions; other- 

 wise, each definition has its own refer- 

 ence number, if applicable. Definitions 

 containing no source number represent 

 the opinion of the contributing specialist 



or a major modification of an existing 

 definition. 



As a further guide to the user, ap- 

 pendixes are included which contain in- 

 formation of possible interest, although 

 not necessarily within the basic scope 

 of a glossary. Appendix A contains 

 abbreviations and acronyms related to 

 oceanography-oriented Navy projects, 

 operations, and equipment and scientific 

 usage in general. Appendix B contains 

 abbreviations, titles, and locations of in- 

 stitutions, agencies, activities, and 

 groups currently engaged either directly 

 in oceanography or in work in closely 

 allied marine sciences.
