over long intervals of time with the measuring transducers 

 at a height above bottom that is comparable to the size of 

 the fauna studied. Arrays of current meters would be useful 

 for the computation of flow regimes. Correlated temperature 

 measurements would allow for the determination of tempera- 

 ture fluctuations experienced by the fauna. Measurements of 

 the concentration and composition of suspended particulate 

 matter are also needed. 



Additional studies are also recommended to fill gaps 

 in the existing data base. The present study has identified 

 canyons as unique in that they provide a heterogeneous 

 environment for many of their faunal constituents. However, 

 comparable data on slope environments and their fauna is 

 very sparse. Additionally, the obstacles created by lobster 

 pot arrays prevented adequate coverage of the shallower 

 depth intervals in the northern canyons. A better understand- 

 ing of the dendritic flow patterns of canyons would also be 

 useful in determining the dissemination of by-products of 

 resource development.
