1 adjacent areas; in fact, the evidence would support the conclusion that 



2 they will receive materials. 



3 DR. TEAL: I think the evidence is stronger than that. The 



4 evidence is that they receive relatively more material from the shelf 



5 than the general slope. 



6 DR. KRAEUTER: That is really what I was getting at. We are 



7 talking about something that you need a greater-- 



8 DR. BUTMAN: I'm not sure we do. Do we know that? 



9 DR. TEAL: That's a good question. That's what I saw some of your 



10 geochemical studies as saying, that there was a relative increase in the 



11 material accumulating in the canyon. 



12 DR. BOTHNER: Again, it is a question of which canyon you are 



13 looking at, but the small amount of data would suggest that the 



14 potential for accumulating contaminants is higher in Lydonia Canyon than 



15 it is on the slope. 



16 I would love to analyze samples from Oceanographer to see if that 



17 holds true. In spite of the fact that we think that is an erosional 



18 area, I think there is still a potential for intense scavenging in 



19 Lydonia Canyon by the very small amount of fine grained material that 



20 exists in the bottom sediments, even within the axis, that will be very 



21 important in enhancing the pollutant load for those pollutants that are 



22 reactive to surfaces of particles. 



23 DR. BUTMAN: I guess I was thinking that this is particles. 



24 Whether they actually increase the--so, all right. Is there any other 



25 information we heard discussed that should be added to that list which 



26 says that particles--either sand or fines--enter the canyon from the 



27 shelf? 



28 Does everybody agree that that is true? 



29 DR. RAY: I want to come back and follow up, ask something else, 



30 following up on what John just asked and that was, in the perception of 



31 the canyons in this area as to whether or not they are--you know, you 



32 are saying they are a primary mechanism for the transport of particulate 



33 off the shelf and onto the slope.
