ADVANCEMENT OF MARINE SCIENCES 73 



6. Studies of the effects of the biosphere on the distribution and 

 circulation of radioisotopes in the oceans, its seas, and the Great 

 Lakes. 



7. Studies of the genetic effects of atomic radiations on marine 

 organisms. 



8. Field experiments in confined bodies of water using or utilizing 

 radioisotopes. 



9. Two major open sea tests of radiological contamination at sea, 

 its effects on marine life, and its potential effects on humanity. 



Committee amendments to section 12 



Page 33, line 24, strike the figure "$1,400,000" and substitute the 

 figure "$2,800,000". This change, applicable to the authorization of 

 appropriations for research to determine circulation and mixing proc- 

 esses which control the dispersion of radioactive wastes in deep waters 

 of the open ocean, was made by your committee following staff con- 

 sultations with atomic scientists. 



Page 34, line 2, following the word "sediments," strike the colon 

 and substitute a semicolon, and strike the words : 



Provided, however, That expenditures by the Atomic Energy 

 Commission for this purpose not exceed $484,000 in the fu-st 

 year of the program or $299,000 in subsequent years of this 

 10-year period. 



This proviso was considered unrealistic by the committee following 

 staff consultations with a representative of the Atomic Energy Com- 

 mission. 



Page 34, hne 9, following the word "Lakes" strike the colon and 

 substitute a semicolon, and strike the words : 



Provided, however, That expenditures by the Atomic Energy 

 Commission for this purpose not exceed $968,000 per annum. 



This authorization is for studies of the effects of the biosphere on the 

 distribution and circulation of radioisotopes in the oceans, its seas, 

 and the Great Lakes. The reason for removing the Umitation is the 

 same as given in the preceding amendment. 



Page 34, line 13, following the word "organisms" strike the colon 

 -and substitute a semicolon, and strike the words: 



Provided, however, That expenditures by the Atomic Energy 

 Commission for this purpose not exceed $100,000 per annum. 



The authorization referred to relates to studies of the genetic effects 

 of atomic radiations on marine organisms, and the committee, on the 

 advice of scientists, deleted the limitation as unduly restrictive in 

 the event of the occurrence of profound effects. 



Department of the Navy 



Section 13 would authorize and direct the Secretary of the Navy, 

 ivith such funds as may be appropriated or otherwise made available 

 to him, to carry out the following activities: 



1. Undertake a 10-year program of expanded oceanographic re- 

 search and hydrographic surveys as part of the U.S. program for the 

 development of the marine sciences.
