THE PROBLEM 



Conduct tests to determine which cables are most suitable 

 for oceanographic applications. 



RESULTS 



1. Extensive tests were conducted on 14 cables now in 

 general use for marine operations, to determine their resistance 

 to elastic and rotational stretch. 



2. The 3 x 19 cable was found to have characteristics that 

 would favor its use for sensitive oceanographic problems when 

 compared with the other cables tested. 



RECOMMENDATIONS 



1. On the basis of the evaluation reported here, consider 

 the 3 x 19 cable the most suitable of those now available for pre- 

 cision oceanographic applications. 



2. In future procurement of oceanographic cables, conduct 

 similar tests on sample lengths before adopting any new types. 



3. Continue investigation of new cable designs for oceano- 

 graphic use.
