1 In this method what we're doing is calculating the number of 



2 species that we expect to find in a set number of individuals from the 



3 station. We calculate this for a range of individuals from 50 up to the 



4 exact number that was found in a particular station. 



5 That is why you see dots along these curves. These represent 



6 individual points that were calculated in order to draw the curve. 



7 Station 8 on the slope had a much higher diversity. Its curve is much 



8 higher than either of the two canyon stations, which are labeled 7 and 



9 7A. 



10 For reference, the two lines on the bottom of the slide labeled 



11 13A and 13, represent stations in the mud patch. The most diverse 



12 stations in this particular slide were at about 145 meters on the slope. 



13 In fact, station 16 was one of the drill sites, it was a site in block 



14 410. 



15 For the similarity analysis one of those clustergrams again. 



16 First I just want to show you, if you look at the top part of the slide, 



17 and keep in mind the lower the crossbar, the more similar the two 



18 samples, because it's on a scale of zero to one. We're using a NESS 



19 similarity index. It's not the same index that Barbara used, so the 



20 scale looks a little bit different. 



21 The closer any two stations are to each other and the lower the 



22 crossbar, indicates that they are more similar to each other. The 



23 bottom part of the slide shows you the station--it's an indication of 



24 the station depth and the sediment composition. 



25 The thing to note from this particular slide is that none of the 



26 three stations we were looking at 150 meters were at all similar to each 



27 other. 



28 Here's our fine-sediment canyon station and what this tells us is 



29 that it's more similar in terms of faunal composition to the mud patch 



30 stations. Station 7 here is that coarse sediment station on the canyon 



31 wall. It's most similar to a station that was near the head of 



32 Oceanographer Canyon. 



33 Station 8 is our slope station, and it's clustering very tightly 



34 with the group of slope stations at about 145 meters. At 150 meters our
