Surrounded by collecting 

 bags, bottles, knapsacks, 

 and other paraphernalia 

 cherished by naturalists, 

 Dr. J. P. E. Morrison, As- 

 sistant Curator of Mol- 

 lusks at the U.S. National 

 Museum, examines a sea- 

 faring bird caught at Bi- 

 kini. Careful censuses 

 were made, both before 

 and after the explosions, 

 of principal types of ani- 

 mal and plant life. 



Sonobuoys to be used in the two Tests are inspected before being 

 moored in assigned positions in the target area. The column mounted 

 above the buoyancy barrel carries a horizontal, eight-sided loop serv- 

 ing as artificial electrical ground. Above this may be seen the small 



vertical antenna.
