MR. E. G. ANDREWS (Sanders Associates, Inc.): Is data pub- 

 lished on the behavior of electronic equipment under environmen- 

 tal conditions as discussed by you this morning? If so, where will 

 we have access to that data? 



MR. J. M. SNODGRASS (SIO): Some very small amount, rather 

 sketchy, has been reported in some of the progress reports in the 

 Scripps Institution of Oceanography. 



There is also some, I think, in the November and December 

 (I960) issues of the progress reports of the Naval Research Lab- 

 oratory in Anacostia. 



Two papers, I believe on this same subject, by the same 

 authors that wrote the articles appearing in the Naval Research 

 reports will be given at Woods Hole Oceanographic Institution, 

 I think, on September 14 at the ISA meeting. (ISA Journal, Novem- 

 ber 1961, Buchman and Flato. ) 



DR. ALFRED A. WOLF (Emertron, Inc.): Would the measure- 

 ment of attenuation and phase characteristics of large volumes 

 of sea water automatically be of any value? 



CAPTAIN C. N. G. HENDRIX (HO): Yes, it would be very appli- 

 cable to and necessary to the propagation of sound particularly in 

 this oceanographic area, as it applies to the various sonar prob- 

 lems. 



CAPTAIN R. D. FUSSELMAN (HO): In the general evaluation of 

 some of our sonar equipments, it is now generally accepted, 

 through all our Navy agencies, we will have some pretty good 

 oceanographic teams to try to deternnine how some of these per- 

 fornnance factors of new equipnnents correlate with general 

 oceanographic conditions. 



We think that there is a tremendous appreciation of this whole 

 problem. We hope we are going to be able to tell why this thing 

 is doing as it is. 



MR. HARVEY WEISS (Grumman Aircraft Engineering Corpora- 

 tion): Concerning instrumentation component deviations as a result 

 of pressure increases, do you know of any work going on concern- 

 ing the variation of mass movement of inertia of uniform shapes as 

 a function of pressure?
