214 OCEANOGRAPHY 1961 — PHASE 3 



direction of arrival cau be determined, and if the velocity structure of the water 

 or the rocks is understood, further deductions may be made about the position 

 of the source. If the signal is weak with respect to the noise its relative level 

 can be raised by suitable treatment. All these techniques have been exploited 

 by the exploration industry for the knowledge it must have about the attitude of 

 the hidden geologic layers. Mapping the ocean bottom, the geologic structure 

 below it, and any anomalous bodies such as submarines which may be present 

 under the surface is in a sense exactly the same problem. In general, the same 

 kind of research facilities and the same kind of research workers are required to 

 solve it. 



It is in the problem of data processing that the capabilities of the exploration 

 industry could perhaps have the most important effect on oceanographic instru- 

 mentation. The central problem of oceanography to date is to provide in as 

 much detail as is usable, a synoptic picture of the entire ocean. This means a 

 knowledge of the temperature, salinity, current vector, biological content and 

 other variables, for any point at any time. To collect such knowledge, process 

 it, and make it available, without making the result prohibitively cumbersome, 

 can obviously be done only by automatic methods of data recording, computing, 

 and storing. These methods are receiving full development in exploration geo- 

 physics today and could be applied without difficulty to oceanography.

Mr. Miller. Dr. Mott-Smith ? 



Dr. Mott-Smith. As far as I am concerned, sir, I think the sub- 

 ject is very well covered. 



Mr. Miller. May I just ask you this : Do you subscribe generally 

 to what Dr. Blake and Mr. Savit have said ? 



Dr. Mott-Smitit. Yes, sir, I do. 



Mr. Miller. How about you, Mr. Romberg '^ 



Mr. Romberg. Yes, I think I concur with what they said, and I 

 think they stated the case very well not only for my company but for 

 the industry as a whole. 



Mr. Miller. The meeting, then, will stand adjourned until 10 o'clock 

 tomorrow morning. 



(Whereupon, at 12:15 p.m., the subcommittee was recessed, to re- 

 convene at 10 a.m., Wednesday, June 21, 1961.)
