NOTE: Results of the 5-m2 quadrat sampling of the benthic community are presented in Part I as percent cover; counts of 
diurnally exposed macroinvertebrates are given in Part II, and a summary of the fish census is given in Part III. Water depth 
ranges from 10.7 to 11.6 m; mean coral coverage is 5.2% (quadrat method).
