1 The floor of Lydonia Canyon, galatea crab, tilefish. Veatch 



2 Canyon, pueblo village community, it's about a 40-pound female. I think 



3 this is a cleaner fish, there's conger eel in here. You'll see this guy 



4 twist 360 degrees, one of two cycles here. He may be scraping off 



5 ectoparasites, or that may be his way of enlarging or shaping that 



6 tunnel . 



7 The last thing that I want you to see and then I'm going to turn 



8 this off so I don't run over. This is the floor of Lydonia Canyon, a 



9 large tilefish population there you never would have expected, and we 



10 think it's a depositional environment. 



11 This is about a 40-pound fish at depths of 500 to 1,000 feet in 



12 the axis of the canyon, one of our site-specific stations. This is 



13 typical and very predictable behavior of tilefish. They'll back out 



14 until they get eye contact and then dive back in. 



15 I'm going to fast forward to one more scene of a lobster feeding 



16 on a Jonah crab. Lobsters are very abundant in this area as well. This 



17 is 584 feet, Lydonia Canyon, type 1 habitat. 



18 One or two tenths of a knot current. You never observe any 



19 currents here of about more than several tenths of a knot. This is a 



20 depositional type environment, as I would judge it. 



21 I apologize, I occupied most of my 5 minutes that I lost at the 



22 beginning, so if there's no objection, I'll step down. 



23 DR. MACIOLEK: Does anyone have a quick question for Dick? I 



24 guess they'll wait until the coffee break. 



25 Our next speaker is Dr. Brad Butman from the U.S. Geological 



26 Survey in Woods Hole, and the title of his talk is, "The Lydonia Canyon 



27 Experiment: Circulation, Hydrography, and Sediment Transport."

31 DR. BUTMAN: Good morning. I'd like to present some results from 



32 the Lydonia Canyon Experiment, which was a major experiment which was 



33 conducted between 1980 and '82 by the USGS, with support from the 



34 Minerals Management Service and also USGS.
