Dear Mr. Cuarrman: In response to your request, I am submitting 
a comprehensive report on ocean pollution. 
The report, entitled “EKifects of Man’s Activities on the Marine 
Environment,” describes most of the salient aspects of ocean poliution 
beginning with the importance of preserving the ocean resource, 
through man’s activities that generate marine pollution, specific marine 
pollutants, private international organizations concerned with marine 
pollution, United Nations conventions and United States legislative 
activities, and current technology for abating ocean pollution. The 
appendixes include lists of harmful substances in the sea, international 
conferences and agreements for controlling marine pollution, recom- 
mendations of the UN Conference on the Human Environment, and 
the recently drafted international conventions on the dumping of 
wastes and prevention of pollution from ships. 
The report was prepared by Dr. James EK. Mielke, Analyst n Marine 
and Earth Sciences. 
We hope that this report serves your committee’s needs as well as 
those of other committees and Members of Congress concerned with 
marine pollution and the National Ocean Policy Study. 
Sincerely, 
Lester S. Jayson, Director.
