MR. RUSSELL E. HUKEE (Imperial Electronics, Inc.): Is there a 

 requirement for a temperature to frequency converter? 



MR. B. K. COUPER (BUSHIPS): Increased efficiency of informa- 

 tion transmission is always of interest, especially if the technique 

 is more economical, reliable, and easily maintained. The value 

 of the technique you mention would depend on how it contributes 

 to any or several of these qualities in the actual system of which it 

 would be a part. 



MR. WILLIAM HILDRETH (Lockheed Aircraft Corporation): Is 



an Encyclopedia on Oceanographic Ins trumientation to be published? 



THE CHAIRMAN: We have not fully decided whether or not to pub- 

 lish these several volunnes of the encyclopedia. If there seems to be 

 enough interest in Industry, in Governnnent, and in non-govern- 

 miental laboratories, we will publish thenn. It nnay be published 

 for the ICO by a staff on contract. These several volumes at 

 the back of the room are too bulky to be included in the Proceed- 

 ings of this particular mieeting. An indication from you concern- 

 ing an interest in the encyclopedia will help us to make a decision 

 in this regard. 



DR. ROBERT S. BRAMAN (Armour Research Foundation): Would 

 you please comnnent on the use of nuclear techniques in auto- 

 miatic sensing devices? 



DR. I. E. WALLEN (AEC): Nuclear energy offers long-term, 

 reliable, lightweight power sources for sensing devices. Because 

 of the limitations of production and the high purity requirements 

 of suitable materials, these power sources are expensive for 

 the usual types of oceanographic observations. 



When remote operations or special use requirements demand 

 reliable performance for several years, my opinion is that wide 

 use will be miade of these Systems for Nuclear Auxiliary Power 

 (SNAP) units. 



MR. R. B. PRIEST (Fairchild Camera and Instrument Corpora- 

 tion): How much use has been made of television in oceanography? 

 What results have been obtained as to range of view and depth of 

 operation with artificial light and with natural ambient light?
