SUDE No. 11 



The drum lift and recovery system was fairly standardized by the 

 time we undertook this survey, although we had only recovered 

 two drums; once in 1976 in the Atlantic, and once in 1977 in the 

 Pacific. In this 3,800-meter site instead of using a winch on the ship 

 to recover a drum from the bottom we used a direct lift with the 

 ALVIN submersible, since this was a 55-gallon drum and consider- 

 ably lighter than the 80-gallon drum recovered from the Atlantic 

 2,800-meter site in 1976, a report on which I have enclosed for the 

 record. The drum was brought up very close to the surface with a 

 harness underneath the submersible, and then the line was at- 

 tached to the ship's winch and it was hoisted the last few hundred 

 feet. 



Standard radiation protection procedures were in place. All per- 

 sonnel handling the drum had to wear special clothing, and they 

 all had film badges to record any radiation exposure. There was a 

 rubber sheet over the deck to protect it. As we will see in the next 

 slide the drum was immediately placed into a jet-engine container. 



I should also add that everybody who came anywhere near this 

 drum had a film badge. There was no exposure reported for any of 

 the personnel.
