1 slowly working his way up from about 800 feet to 490 feet in the 



2 northeast corner of Oceanographer Canyon. 



3 What we've done is take short segments, 10-, 20- and 30-second 



4 segments of what, in essence, was about a 2 hour tape climbing up this 



5 escarpment. 



6 You'll see how effective these animals are in restructuring and 



7 moving sediment in these canyon head environments. A trawl or a dredge 



8 would do just absolutely havoc to these kinds of environments. 



9 It took many years to train Page to identify a few species of 



10 fish, but after about 10 years he got pretty good at it. 



11 (Laughter) 



12 You're at the base of talus slope now, silt blocks. We're 



13 starting to climb almost a vertical wall. You see this is ^^ery 



14 predominantly a white hake/ocean pout community. These dives were made 



15 in the summertime in July, consistently, for 5 years. 



16 Just a minute and we'll get into the shrimp and tilefish habitat. 



17 I'll show as much of this as I can during my allotted time and I'll be 



18 glad to show you the rest of it over coffee break or this evening or 



19 over lunch. There's quite a bit of information in this. 



20 This straight area is biological in origin. Again, if we were out 



21 here at this time of year, a lot of these holes would be filled with 



22 lobsters. 



23 DR. HECKER: Dick, what's that fuzz on there? Is that a hydroid 



24 [phonetic], that fuzz? 



25 DR. COOPER: Yes, I believe that's what it is. This is a rock 



26 pile, type 3 habitat, glacially deposited in the northwest corner of 



27 Oceanographer, one of our site-specific stations that we monitored for 4 



28 years. This is a white hake/ocean pout community. 



29 You might say, why don't you find lobsters there? The white hake 



30 is a voracious predator of small lobsters. Lobsters have very 



31 distinctive habitat, as you'll see in just a minute or two. 



32 Unfortunately, the most commercially valuable of all the species 



33 out there are the lobsters, so highly nomadic and migratory in behavior, 



34 and respond so quickly to 0.1 degree change in centigrade in bottom
