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 
biochemical behavior of the oceans cannot satisfactorily be pre- 
dicted. 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.
