1 indicated that this group here joined at this level, are all of our 



2 , samples from station 4, which was our slope station. 



3 The station that it is most similar to turns out to be station 12, 



4 which was at the same depth, 550 meters on the slope, but several 



5 kilometers distant. 



6 It's not at all that similar to our canyon station, station 7, 



7 which is indicated here. You can see the level of similarity is just 



8 si ightly over .4. 



9 Turning to the 2,100 meter depth, this slide is from Barbara 



10 Hecker's photo transects, and it's at about 2,100 meters or 2,160 meters 



11 in the canyon. Barbara had labeled it crinoids, so I assume that these 



12 are the crinoids that you had indicated. 



13 At the slope adjacent to the canyon, we had two stations that were 



14 located on the slope outside the canyon. They both have this type of 



15 surface feature, fairly fine-looking sediments, the Ophiomusium, some 



16 mounds, some burrows, so there is some biological features, but 



17 essentially the two stations look very similar in these photographs. 



18 At 2,100 meters, we find a very different story that we saw either 



19 at 150 or 550. At this depth we have the same small polychaete, 



20 Aurospia dibranchiata as the dominant at all three of the stations. It 



21 occurs in about the same proportion at each of them, that is it accounts 



22 from somewhere between 8 and II percent of the community. 



23 This same species is the top dominant in the infaunal benthos, 



24 essentially along the east coast of the United States at 2,100 meters 



25 depth. While I can say it's at least from the U.S. -Canadian boundary 



26 down to as far as Cape Hatteras and then some other organisms take over 



27 some of the dominance of the communities. 



28 This is a very common species and we can see that as far as the 



29 canyon or the slope stations are concerned, it's dominant at all three 



30 of them. 



31 Furthermore, if you again look at the top 20 dominants at these 



32 three stations, 11, depending on which slope station you're looking at, 



33 11 or 12 of them are shared with the slope. In other words, the
