nomically satisfying to relabel these compo- 

 nents with the same terms, one might find it 

 difficult to communicate with the owner 

 whose vehicle has been redesignated. 



Finally, we arrive at units of measure or, 

 more precisely, the metric system versus the 

 English system. Quite evident is the fact that 

 nothing has been done herein to advance the 

 metric system. Recognizing the practicality of 

 it over the English system, the conversion of 

 the many values from the latter into the 

 former represents a job of considerable magni- 

 tude and leads to strange dimensions. A 6- 

 foot-diameter pressure hull would become one 

 of 1.83 meters and still not be an exact meas- 

 urement. So to simplify matters, where the 

 original data are in meters, it is so reported, 

 and where feet and inches are used, they are 

 given. And, as a final apology, a table to 

 convert the various units is included in Ap- 

 pendix I. 



General and Specific Publications of 

 Interest 



Throughout the text reference is made to a 

 variety of books, articles and reports dealing 

 with specific design aspects or operations of 

 submersibles. For the reader who might be 

 interested in only one vehicle or particular 

 components of submersibles, the following 

 books or reports, though referenced later, are 

 noted:

The Woods Hole Oceanographic Institution 

 beginning in 1960 issued yearly reports on the 

 design, construction, operations and modifica- 

 tions to ALVIN. The first 2 years deal with 

 ALUMINAUT, which at that time was a coop- 

 erative venture between the Navy and Rey- 

 nolds International, but from 1963 on through 

 1970 they deal only with ALVIN. These reports 

 are entitled Deep Submergence Research and 

 each covers a calendar year during the above 

 period. Unfortunately they are not widely dis- 

 seminated, but are available at WHOI and 

 may be found in university libraries where 

 oceanographic courses are offered. Careful 

 reading of these is literally a course in deep 

 submergence components and the painful 

 progress of making a manned submersible a 

 useful scientific tool. One of the main deficien- 

 cies with most reports describing modifica- 

 tions to submersibles is that the author tells 

 what has been changed but not why it was 

 changed or what was the problem. The WHOI 

 reports, on the other hand, provide all such 

 details, and they explain each change in de- 

 tail: Why each change was made, what the 

 component or system was lacking and how the 

 new approach is intended to improve the vehi- 

 cle, its support platform and its launch/re- 

 trieval system. They constitute, in substance, 

 a technological stroll through deep submer-
