A-39 



non-descript sea pens (not identified to species level) are 

 found throughout the study area. 



Acanella arbusoula , Pennatula sp. and Flabettum alabas- 

 tvum were found on the deeper part of the continental slope 

 south of Norfolk Canyon. In the axis of Norfolk Canyon the 

 coral population is dominated by Flabellum alabastvum , 

 Pennatula sp. and Anthomastus grandif torus on the soft sub- 

 strates, with occasional occurrences of Aaanthogorgia armata 

 and Desmophytlum cvistagalli where outcrops were exposed. 

 Deeper at the mouth of the canyon Eunephthya fruticosa was 

 seen along with the soft substrate corals. On the slope just 

 south of Baltimore Canyon Aaanella arbusaula , Pennatula sp. 

 and Flabellum alabastrum were seen. 



White fluffy sea pens were the only corals found in the 

 heads of Carteret and Toms Canyons. Deeper at Deep Water 

 Dumpsite #106 populations of Eunephthya fruticosa , Pennatula 

 sp. and Anthomastus grandiflorus were seen. An outcrop in 

 this area provided the necessary substrate for Paramuriaea 

 borealis , Aaanthogorgia armata, Desmophyllum cristagalli and 

 Anthomastus agassizii . 



Only sea pens were found in the main part of Hudson 

 Canyon. Eunephthya fruticosa and sea pens were found in the 

 deeper portion of this canyon. Corals observed in a number 

 of dives on the deep continental slope near Alvin Canyon 

 include Acanella arbuscula, Flabellum alabastrum, Aoantho- 

 gorgia armata, Paramuricea borealis and sea pens.
