FULL FATHOM FIVE. Underwater photography 

 was used at Bikini to record damage to hulls and 

 superstructures of sunken vessels. This work was 

 especially significant after Test Baker, in which a 

 particularly large fraction of the interesting me- 



chanical damage occurred on ships which sank. The 

 diver shown is preparing to descend from the spe- 

 cially equipped LCM used in this work. He wears 

 a simple face mask and a quick-release type of 

 lead-weighted belt.
