XXI. Woods Hole Oceanograpliic Institution, Woods Hole, Mass. 

 Nonr 1367(00)— Cost-type contract Nli 261-102 : 



Fiscal year 1959 (period: Nov. 1, 1958, to Oct. 31, 1959) $1,189,000 



Fiscal year 1960 (period: Nov. 1, 1959, to Sept. 30, 1960) 1,150,000 



The objective of this task is to continue the investigation of characteristics 

 of the ocean as they pertain to acoustic transmission. These characteristics 

 and effects are being studied as a function of location, season and weather 

 conditions and the frequency, directivity, and power of the transmission signal. 

 The study includes reverberations, transmission paths, signal sources, improved 

 methods of data storage and analysis, and interrelation of salinity, temperature, 

 density, and sound velocity and target effects on acoustic transmissions. Ex- 

 tension of the explosive echo ranging techniques through use of the directional 

 characteristics and the signal composition are being studied. Data collection is 

 conducted primarily from research vessels and is followed by the detailed 

 analysis and correlation with previously obtained data and reporting of results. 



XXII. Savannah Machine & Foundry, Savannah, Ga. (Chain) ; 

 Mobile Ship Repair Co., Mobile, Ala. {San Carlos). Allotment 501 

 (MSTS)— Cost-type contract plus fixed fee NR 261-119: 



Fiscal year 1959 (period : July 1, 1958, to June 30, 1959) $2, 500, 000 



Fiscal year 1960 (period : July 1, 1959, to Jime 30, 1960) 1, 400, 000 



In fiscal year 1959 this task provided funds to the Military Sea Transportation 

 Service for activation, alteration, and operation of the U.S.S. San Carlos (AVP- 

 51) and the U.S.S. Chain (ARS-20) for use as research ships for Hudson 

 Laboratories of Columbia University and the Woods Hole Oceanographic Insti- 

 tution respectively. The San Carlos is now in service as the USNS Josiah 

 Willard Gibbs T-AGOR-1) and the Chain has been leased to the Woods Hole 

 Oceanograpliic Instituiion by the JJnreau of Siiii>s. 



In fiscal year 1960 the funds cover the cost of operation by MSTS for the 

 entire year for the Gibbs and to November for the Chain. 



XXIII. Sciipps Institution of Oceanography, University of Califor- 

 nia, La JoUa, Calif. Nonr 2216 (65)/ (10)— Cost-type contract NR 

 261-115/129 : 



Fiscal year 1959 (period: Sept. 1, 1958) $1,000,000 



Fiscal year 1960 (period : Oct. 1, 1959, to June 30, 1960) 850, 000 



The Marine Physical Laboratory is conducting research on the generation, 

 transmission, and detection of acoustic and electromagnetic energy in the ocean 

 and the media bounding it. Their program also includes basic studies in geo- 

 magnetism, gravity, and other force fields or energy sources in the ocean. In- 

 dicated naval applications are investigated as they arise and the solution of 

 Navy problems in these areas undertaken. 



In addition, the research program at MPL has, for many years, included basic 

 research in the field of sonar signal processing has led recently to the extended 

 application of digital computer techniques to this problem. The objective of this 

 task is to further research in this highly promising field and to validate theoreti- 

 cally demonstrated advantages of the concept through sea experiments.
