SuDE No. 9 



Here we see one of the first drums that we observed from the 

 submersible. It is a standard 55-gallon drum. It shows the typical 

 corrosion along the chimes and weld points, and yet it is in fairly 

 good condition. It has been lying on the ocean bottom in excess of 

 16 years. 



Again, you can see the talus slump blocks around the drums and 

 the drum corrosion products on the sediment surface. We can also 

 see in this photo indication of the direction of the current. It is 

 moving toward the viewer, in a southerly direction. Corrosion prod- 

 ucts can be seen in the foraminiferal sands which have been build- 

 ing up behind the drum, along its long axis. 



On the other side of the drum we observed that the sediment had 

 been scoured out considerably. 



In the background the rat-tail fish, C-o-r-y-p-h-a-e-n-o-i-d-e-s a-r-m- 

 a-t-u-s is visible. This is the most ubiquitous fish and we have seen 

 it in all of the deep sea dump sites. It is found at 2,800 meters and 

 3,800 meters. It is probably an important link in any food chain 

 transfer from deep-sea disposal sites since it has been found in 

 most of the deep-sea regions throughout the world. What is most 

 interesting about the last few slides is the great variability shown 

 in the sea bottom features over relatively short distances. 



Next slide, please.
