capsule mating with a deck decompression chamber was used for accomplishing re- 

 covery and decompression of aquanauts. 



Sealab II demonstrated that: 



1. The concept of ocean- floor habitation to accomplish a wide range of 

 salvage and scientific tasks is compatible with man's ability to perform 

 useful work at these depths. 



2. No significant short-time physiological changes occur which resulted in 

 deterioration of the aquanauts physical condition. 



3. There is a degradation of human performance which increases with the 

 complexity of the task being accomplished.
