Near Bottom Transport 



10. A system for transporting 10- to 30-ton loads for short distances in 

 tine near bottom environment is considered feasible. 



11. The two most promising concepts are a submersible with a gas 

 generator for displacing water ballast and a hydrocopter, dependent on 

 mechanical means for generating lift. 



12. Final choice between the two concepts must await further definition 

 of work missions and load configurations.
