A-57 



was particularly helpful in allowing us to review his collec- 

 tion of photographs from DWD-106 and providing us with the 

 perspective grid for the earlier ALVIN dives. David Ross of 

 WHOI also provided us with photographs from dives in Lydonia 

 Canyon. We are very grateful to Alexander Malahoff and 

 Robert Embley of NOAA in Washington, D.C. and Daniel Fornari 

 of L-DGO for providing us with the photographs, dive tracks, 

 and dive transcripts for their mid-Atlantic canyon dives. 

 We would also like to thank John Kofoed, Evan B. Forde , 

 Peter A. Rona, and George Freeland of NOAA in Miami, Florida 

 for providing maps, allowing us to review their dive photos, 

 and sharing their ideas concerning the dynamic processes of 

 the mid-Atlantic canyons. Special thanks go to 

 Richard Slater of the University of Northern Colorado for 

 making his submersible photograph collection available to 

 us, for providing facilities for collecting data, and for 

 giving us access to all the background information on the 

 dives. Thanks also go to George Keller of Oregon State 

 University for sending us his film and dive tracks from 

 early submersible work in Hudson Canyon. Richard A. Cooper 

 and Joseph Uzmann of NMFS at Woods Hole very kindly provided 

 us with a review of some of the dominant fauna seen in their 

 survey of the canyons. We owe special thanks to the WHOI 

 Deep Submergence Group, particularly Jack Donnelly who 

 provided us with the logs of ALVIN dives.
