Summary. 
From the discussions at Woods Hole on August 6, 1954 it 
was clear that recommendations regarding sea disposal of radioactive 
wastes could not be made. The uncertainty regarding safety of sea 
disposal stems from the fact that the physical, chemical and bio- 
chemical behavior of the oceans cannot be satisfactorily predicted. 
Rates of circulation, diffusivity and turnover in the oceans have 
not been firmly established. 
There are many technical aspects to be explored even before 
experiments can be designed to evaluate the possibilities of sea 
disposal. The greatest drawbacks appear to be: (a) the lack of 
suitable electric conductor-cables to go deep in the ocean and 
(b) the lack of suitable instruments to measure low levels of 
activity under water.
