Finally, we enter the trenches, which, in this case is manned by 

 typists, illustrators, and photographers. My appreciation is extended to 

 Mr. Dick Moody of the Office of the Oceanographer of the Navy, who 

 waded through the morass of governmental contracting to somehow 

 see all the illustrations through to timely and accurate completion. Mr. 

 Carl Mueller, also of the Oceanographer's Office, performed all photo- 

 graphic reproductions and processing and still exchanges hellos after 

 my countless changes of mind, format and requests for processing. Mrs. 

 Becky Murray, another OCEANAV employee, had the questionable 

 honor of typing the final drafts of this manuscript and did much to 

 impose a degree of consistency and order to a most incorrigible subject. 



The photographs which appear with NAVOCEANO (Naval Oceano- 

 graphic Office) credits were taken by members of its Deep Vehicles 

 Branch which functioned from 1966 through 1970. During this period, 

 in which I was the nominal head of the Branch, its members contrib- 

 uted not only photographs, but a wide variety of practical expertise 

 and critical observations fi'om which I drew heavily to display my 

 "expertise." Specifically, I am grateful to Roger Merrifield, Joe Pollio, 

 Mike Costin, Larry Hawkins, Pete Bockman, Tim Janaitis, LeRoy 

 Freeman and Dick Young for their years of patience and enthusiasm 

 while I fumbled through the alleged role of "Leader." 



My final thanks and gratitude are to Miss. Jean Michaud, my 

 anchorman. Typing the first hand-written chapter as a favor, her 

 involvement grew to providing all subsequent typing and the necessary 

 nagging to keep the work going when the task seemed unending. Her 

 help, encouragement and loyalty were direct contributors to its timely 

 completion.
