organisms; also any interactions between waste materials and the physical 

 and chemical properties of sea water. This includes toxic effects on 

 the marine organisms; concentration of toxic chemicals and pathogenic 

 organisms in the food chain of edible marine food resources; the 

 mechanisms causing paralytic shellfish poisoning and poisonous fish; 

 understanding of the biology of marine organisms which may lead to their 

 control in assimilating pollutional materials; the survival rate of 

 pathogenic organisms in the marine situation; generic studies of marine 

 organisms which may lead to new knowledge of human life and health; and 

 studies to determine any medically or pharmacologically important 

 substances which may be produced by marine organisms. 



Research studies include the effect of sewage on fertilization and the 

 effect of certain industrial wastes on the productivity of the euphotic 

 zone; oxygen and carbon dioxide relationships with photosynthesis, 

 respiration and growth of marine algae, bacteria and other organisms; 

 and the relationship and effects of radiation and wind movements on 

 biological growth and distribution. Where possible the basic findings 

 of other agencies doing research on radiation and air-sea interface 

 phenomena will be utilized or studied cooperatively. 



During FY-63 the Public Health Service hopes to have completed two new 

 research laboratories, one in New England and one on the Gulf Coast, 

 in support of an expanded National Shellfish Sanitation Program. It 

 also hopes to have in the planning stage a field laboratory and 

 research center for pollution control, including studies of pollution 

 of estuarine and inshore waters. The planned direct oceanographic 

 research program for FT-1963 relating to pollution is as follows: 



1. Chemical and bioassay studies of industrial wastes to 



determine their fate and toxicity in the marine environment; 

 particularly as these affect shellfish, fin fish, and other 

 aquatic life,, Studies of the mechanisms and rates of 

 biochemical reactions in sea water in relation to assimilation 

 of sewage and industrial wastes. 



2o Determination of the longevity and fate in sea water of 

 bacteria and viruses of human origin, •. with special refer- 

 ence to contamination of recreational beaches and harbors, 

 and saline waters that may be converted to fresh water. 



3. Studies to determine the adverse effects of municipal and 

 industrial wastes on shellfish, and of natural environmental 

 factors which make dangerous their ingestion by man or interfere 

 with their reproduction and growth. 



k. Research to develop and perfect instrumentation and pro- 

 cedures for routinely detecting and measuring pollution by 

 radioactive wastes in the inshore and estuarine waters,
