APPENDIX E 



REQUIRED OCEANOGRAPHIC INSTRUMENT SUIT 

 FOR OCEANOGRAPHIC SURVEY VESSELS 



By Captain C. N. G. Hendrix and Working Group 



PREFACE 



In recent conferences and discussions, an attempt has been 

 made to determine the oceanographic instrumentation needs of 

 oceanogr aphic survey vessels. Although the resulting instrument 

 and system descriptions contained herein have been particularly 

 oriented toward outfitting oceanographic survey vessels, a number 

 of these instruments and systems are considered to have additional 

 application to both basic and applied research investigations. 



These descriptions are presented in the combined form of both 

 performance and general engineering specifications. This has been 

 done intentionally, in order to stimulate the needed and desired 

 new thinking and fresh approach that must be applied to oceanogra- 

 phic instrumentation. The engineering specifications have been pre- 

 sented primarily for information and not to restrict or channel 

 thought on how any given problem may best be solved. Likewise, 

 the performiance specifications have been presented as guideline 

 goals, to be improved where possible. Should the state-of-the- 

 art prevent the attainment of one or more of the goals set forth, 

 it may be necessary to consider interim solutions. However, in- 

 terim instruments or instrunnent systems will have to be indivi- 

 dually evaluated on: (1) the inherent merit of the method employed, 



(2) the degree to which the proposal attains the stipulated goal, 



(3) its relationship in time to the achievement of the desired goal, 

 and (4) development and production model costs. 



The priorities, which have been tentatively assigned to the 

 instruments and instrument systemis described herein, have been 

 dictated primarily by the urgency of the requirement for the infor- 

 mation that the particular instrument or system can provide. Unit 

 and development costs, the current state-of-the-art, and the 

 estimated time period required to perfect a particular instrument 

 or system have not entered into the setting of these priorities. 

 Furthermore, these priorities will not prevent the procurement
