 197fi Atlantic Radioactive Waste Dumpsite Survey". 



This'report presents the various scientific operations which were 

 ongoing during the 1976 radioactive waste disposal site survey, where 

 the various sampling stations were located, and the manner in which 

 operations were undertaken.

 Nuclear Waste in the Deep Ocean", August 1978. 



This generic report of deep ocean corrosion processes for steels and 

 concrete explains in easily understandable terms the mechanisms and 

 expected rates of corrosion. The report concludes with recommendations 

 regarding improvement of the reliability of the containers potentially 

 used for future ocean disposal practices.

 of the Atlantic 2800 Meter Deepwater Radioactive Waste 



Dumps ite-Macro-Tnfaunal Analysis", August 1977. 



This report summarizes the findings of an investigation into 

 abundance, biomass and species composition of the benthic infaunal 

 community at the 2800 meter depth site. Age structure was also 

 investigated. The samples were collected as a part of the sediment 

 sampling program with the use of a Soutar box core. 



High species diversity was found. Polychaetes, followed by 

 crustaceans, were the most abundant organisms. No extraordinary 

 organisms or distribution of organisms were discovered.

 Observation of Deepwater Radioactive Waste Dumpsite-106", 

 EPA-520/9-78-001, June 1978. 



The bottom terrain of the 2800 meter radioactive waste disposal site 

 was investigated by direct visual observation using the manned 

 submersible ALVIN. It was found to be characterized by meandering 

 channels, with some boulders and rock outcroppings. The report attempts 

 to interpret the geological history of the site, where major natural 

 disturbances appear to have occurred in the past. The rate of 

 sedimentation at the site is estimated to be 5 cm per 1000 years. 

 Sediment deposition in addition to this, with potential to further bury 

 radioactive waste containers, could occur through future downslope 

 sediment slumping.
