should take into account maximum possible utilization. 



It should not be construed that the oceanogr aphic instrumenta- 

 tion and data requirements of the Bureau of Naval Weapons are 

 limited to the needs of the underwater ranges. Our oceanogr aphic 

 interests extend beyond the ranges. Indeed, it is oceanwide, par- 

 ticularly as it relates to ASW. The sites of the ranges have been 

 selected with certain considerations in mind which do not make 

 them truly representative of the open ocean or the actual ASW 

 tactical situation. Complete evaluation of ASW weapons and sys- 

 tems must occur under these latter conditions. Meanwhile, the 

 ranges seem to present an excellent opportunity to develop, test, 

 and evaluate oceanographic instrumentation that will be required, 

 not only for our own needs, but also for ocean surveillance as an 

 input to such synoptic programs as ASWEPS, basic oceanographic 

 research, and surveys. 



Finally, I add a couple of simple thoughts based on 12 years 

 experience with oceanographic survey instruments. 



First, I want to emphasize the point made by Mr. James M. 

 Snodgrass and Mr. B. King Couper regarding the fact that a 

 considerable body of experience in oceanographic instrumenta- 

 tion has been built up during and since the war. 



I have considered too many proposals that have completely 

 ignored this background. This experience cannot be ignored 

 even though it exists in no neat package, you have to research 

 and to dig for it. 



And secondly, I want to remind you once again that an oceanog- 

 raphic instrument consists of three parts: the sensor, the recorder, 

 and the link between the two. The sensor has to be accurate, relia- 

 ble, and durable. The link has to be reliable and durable, without 

 degrading the accuracy of the sensor. The recorder has to be 

 reliable and durable, also without degrading the accuracy of the 

 sensor. 



The recorder is the area which, I believe, is the least trouble- 

 some but the one with which the proposals seem to be most con- 

 cerned because one can make many beautiful pictures of impressive 

 counters, punches, printouts, eind so on. The part most in need of 

 improvement is the sensor.
