Sealab II, U.S. Navy's "Man-in-the-Sea" project, was low- 

 ered off La Jolla, Calif., in 1965 and emplaced on the sea 

 floor. Its staff conducted oceanographic and geologic re- 

 search, fish studies, and underwent psychological and 

 physiological tests. One finding: an aquanaut living 

 and working from undersea habitat at 200 feet without 

 daily compression can do as much work in 6 hours as 35 

 divers operating from surface. Photo shows staging 

 vessel, crane, and Sealab II, a nonpropelled, submarinelike 

 pressure tank. 



Asberah, 2-man sub used by BCF in Hawaiian waters, 

 helped scientists obtain useful information about tuna 

 and their forage fish.
