1 here created almost entirely through bioerosion, not by current 



2 activity. There are cusks, jonah crab, black-bellied rosefish, galatea 



3 crabs. 



4 A PARTICIPANT: Which canyon is this, Dick? 



5 DR. COOPER: This is in Oceanographer Canyon, northeast corner. 



6 This is the krill, Meganyctiphanes norvegicus that appears to be, 



7 I can't prove this, we are fairly certain that krill is far more 



8 concentrated in these canyon head environments that in the slope 



9 environments. A major source of food for a number of the fishes. 



10 These kind of environments here are where you find your pandalid 



11 [phonetic] shrimps and your juveniles of several hake species. If you 



12 look carefully and you sit on the bottom for a number of minutes, you 



13 can see them move ever so slightly and pick up their presence. 



14 These are high-energy, relatively fast-current, depositional -type 



15 environments. Here's a cusk, related to the cod. These are, again, 



16 very typical pueblo-village type environments. You'll see lobsters in 



17 these. Cusk, conger eel, lobsters, jonah crabs, pandalid shrimp, 



18 cleaner shrimp [phonetic], silt stone outcrops, again bioeroded. 



19 We don't have a good idea as to what the longevity of a given rock 



20 system is, but I'm sure it goes back 30, 40, or 50 years, I would guess, 



21 maybe longer. 



22 That's a basket star, large populations of white hake. This is 



23 about an 8 to 10 pound fish and the ever-present swarm of krill. That's 



24 obviously not the normal concentration of krill. What you're looking at 



25 here is they are attracted to the lights of the sub. 



26 This is about a 1/3-pound lobster, 1/2-pound lobster that's 



27 probably 2 years old. This is a very typical pueblo-village type of 



28 structure. You do not find these environments outside of the canyons, 



29 and especially outside the canyon heads. 



30 They are virtually nonexistent in the outer shelf environments and 



31 they are very rare to see in the open slope between canyons. 



32 This is a white hake here and an ocean pout over here. Page
