Effect of Ocean Turnover on Waste Disposal: According to 
the dissolved oxygen theory of turnover, if radioactive wastes are 
dumped in the high latitudes in the winter time, they would not go 
to the bottom but would sink to around 2500 meters because the water 
produced annually in the high latitudes goes to that depth. If the 
material is put below 2500 meters it might stay there for a very long 
time or at least until there are winters colder than those of 1810 
(16) 
to 1814. 
Possibility of Sargasso Sea for Bulk Disposal. 
Perhaps the best place to discharge radioactive wastes in 
bulk would be into the Sargasso Sea. It contains very few marine 
animals and plants. Based on the barging experience with the acid- 
iron wastes, the contamination should be localized. The most damaging 
concentrations would be behind the barge for a limited distance, 
which is small compared to the whole sea. The waste material will 
go into a lens of water at the surface which follows the circulation 
pattern of the Sargasso. A drift bottle takes 1 to 3 years to circle 
around; it is expected that the waste will drift around in about the 
same length of time. Some of the waste material will be sloughed off 
at the edges into areas of mixing. This will be of concern only from 
the point of view of long term accumulations in the ocean; here again 
it is desirable to know the pattern and time of circulation for the 
whole ocean. 
To sum up, for bulk disposal of radioactive wastes into the 
Sargasso Sea it is necessary to consider: (a) the annual rate of 
pollution, (b) the rate of dispersal of the wastes in the Sargasso
