ACKNOWLEDGMENTS 



Ruth Turner and Austin Williams aided in identifi- 

 cation of molluscs and decapods, respectively. Errors in 

 identification or nomenclature, however, remain our re- 

 sponsibility. Illustration work was done by Michele Cox 

 and typing by Diane McDonnell. John Pearce reviewed 

 the report and made helpful suggestions. We also wish to 

 thank the many persons who served as crew and sci- 

 entists on field surveys and who carried out the bulk of 

 the sorting, identifying, and enumerating of benthic 

 macrofauna.
