 OceanographiG research. — The data provided by the proposed oceanographie 

 surveys will provide a body of information from which significant research 

 contributions can be made. This is especially true when studies of some partic- 

 ular area or phenomenon are planned to provide data for a specific research 

 problem. We must not concentrate solely on the collection of data but must 

 utilize these data to further our understanding of the oceans. This means 

 research both basic and applied. Bureau research oceauographers and Bureau 

 research geophysicists should be the primary ones to work on Bureau-collected 

 data. We must not deteriorate to become a data collector for other agencies and 

 institutions. The end result of this expanded program must not be measiu'ed in 

 miles of hydrography and magnetic data or total number of stations occupied, 

 oxygens titrated, and cores collected. The end result must be measured in terms 

 of the total scientific contribution made as a result of utilization of the collected 

 data to extend man's knowledge and understanding of the ocean and the processes 

 that act within it. 



CONCLUSIONS 



Given the required ships, the Coast and Geodetic Survey is in the singularly 

 fortunate position of having the background and ability to provide the Nation 

 with much of the oceanographie information which, as the recent report of the 

 NAS-NRC Committee on Oceanography points out, is drastically needed to 

 prevent "our being placed in a pi-ecarious position from the .scientific, tech- 

 nological, and military points of view." 



Mr. Miller. Mr. Bauer ? 



Mr. Bauer. With respect to instrumentation of your ships, do you 

 have enough in the way of instrumentation of your ships to permit you 

 to do the oceanographie work that should be done Avhile you are 

 perfonning your hydrographic function 'l 



Dr. Stewart. No, sir. 



Mr. Bai:t:r. Are there any plans for standardization of instiimien- 

 tation in the Coast and Geodetic Survey that would be necessary to 

 perfonn this oceanographie function i 



Dr. Stewart. On our equipment at present, Mr. Bauer, we do some 

 standardization ourselves. In other cases, some of our equipment is 

 standardized by the Hydrographic Oflice. Other types of equipment, 

 for example our current meters, we have had standardized at the 

 Bureau of Standards, sometimes at the David Taylor Model Basin. 

 We have had no trouble actually in getting our equipment standard- 

 ized. 



Mr. Bauer. In other words, to put it succinctly, you are handi- 

 capi>ed in the operation that you could do with a ship at sea because 

 you not have sufficient modern instrumentation. Is that a fair 

 statement ? 



Dr. Stewart. Yes, sir. That is correct. 



Mr. Miller. Has any request been made to the Congi'ess for funds 

 to advance your instrumentation ?
