1 That's a true angle of drop off there. A 50-pound male tilefish, 



2 various species attached, anemones, a black-bellied rosefish, lobster in 



3 a pueblo village. 



4 These are areas around the sort of three-dimensional --attachments 



5 to large boulders like this are where you see a lot of your juvenile 



6 hakes. There's another tilefish grotto. We used hook and line 



7 techniques, paying the surface crew members $25 a fish, a very effective 



8 way to collect fish. 



9 This is a typical tilefish grotto habitat that you see here. If 



10 we were down in Hudson Canyon, these grottos would be much larger. 



11 These tilefish grottos down in Hudson, the bigger ones, would be about a 



12 quarter of the size of this room. We got quite a few of them on tape. 



13 Look carefully, you'll see a number of juvenile fishes living in 



14 the side of this grotto. After looking at some of these tapes here, I 



15 see something that we didn't do during the heat of the study. 



16 I think we have pretty good evidence to suggest that these grottos 



17 and smaller structures make various cleaning stations for shrimp and 



18 various fish. 



19 This is what Hydrographer Canyon looks like. I'm going to fast 



20 forward here. This is the axis of Hydrographer. We sat down there and 



21 a sudden current came from several tenths of a knot to 2 knots going 



22 from south to north at depths of 800 and 1,000 feet here. 



23 I'm going to fast forward real quick. Page is in the back 



24 compartment of this sub. The current is about 1 1/2 knots. You could 



25 sit there on the bottom and actually watch the sand grains blow over the 



26 bottom. 



27 We had all four thrusters in the sub going full tilt and all 



28 ballast tanks flooded and we can't quite maintain our position. We're 



29 facing south, the current is running north. 



30 A PARTICIPANT: Is that up canyon or down canyon? 



31 DR. COOPER: It's flowing up canyon. This is about 1 1/2 knots 



32 here. If you're up here closer, you can see the sand grains and shell 



33 fragments working their way over.
