picture quality or photographs that were not available to us, 

 but from which we collected qualitative data regarding the 

 presence or absence of epifaunal species. Table III is a 

 listing of the location and depth of the camera lowerings re- 

 viewed. For ease in visualizing the geographic location of 

 this coverage all the dives and camera lowerings are plotted 

 on Figure Al . Most of the dives are concentrated in or 

 closely adjacent to submarine canyons while the camera low- 

 erings are more widely scattered. 



A thorough analysis was made of all dives in which 

 picture quality and coverage warranted. The results of this 

 analysis comprise the quantitative data on which this report 

 is based. Unfortunately, the photographs from many of the 

 submersible dives were of poor visual quality, were lost or 

 were not available to us. Whenever possible these dives were 

 then used to obtain qualitative information; particularly 

 data that expanded the known geographic distribution of coral 

 species. Camera lowerings were also utilized to assess the 

 universality of some of the faunal assemblages viewed in the 

 relatively restricted submersible coverage. The archives and 

 sources that were reviewed include: the Smithsonian Institu- 

 tion, Washington, D.C.; Woods Hole Oceanographic Institution; 

 Lamont-Doherty Geological Observatory; the U.S.G.S. (Woods 

 Hole); NOAA (Miami and Rockville, Maryland); and Dr. Richard 

 Slater (University of North Colorado, Greely, Colorado) .
