1 DR. GRASSLE: I guess that, in the interests of making the 



2 document informative, we probably should not be too strict in that 



3 regard. 



4 MR. VILD: All right, so let's go with the asterisk. We will need 



5 a double asterisk. 



6 DR. GRASSLE: I think we need the canyon list that Dick prepared. 



7 He goes down as far as Norfolk, saying that the-- 



8 DR. TEAL: I think that probably the asterisk--as we say, there 



9 are so few data on this point. There are very few data on this point, 



10 so we include the possibly unique situation of sludge dumping in the mid 



11 Atlantic, Mike. 



12 DR. KRAEUTER: We did not say anything about the vertical mixing 



13 sediments as to the canyons-- 



14 DR. TEAL: There is good evidence to that. 



15 DR. KRAEUTER: --but we did not say which canyons. Well, it is 

 15 only in Lydonia that--and, remember, when you deal with the rates of 



17 mixing, this preliminary analysis of the data suggests that there is not 



18 a great deal of difference between the canyon and the slope, so that 



19 rate will not--yes. 



20 The fact that it exists is worth noting, that maybe there is a 



21 sentence there that says, you know, any contaminants introduced will 



22 be-- 



23 DR. TEAL: That is true everywhere. That does not belong in the 



24 table. I mean, it is a known--if the results show that it is not 



25 enhanced, then the answer is "no." 



26 DR. KRAEUTER: If the answer is "no," why not say so? We have got 



27 the evidence. 



28 DR. GRASSLE: I am sorry, how does the vertical mixing tell us 



29 that there is no contaminant? 



30 DR. MACIOLEK: It says that it is not enhanced in the canyon over 



31 the slope. 



32 DR. BOTHNER: Just one thing that falls out of the analysis of the 



33 radioisotopes is the observation that mixing is significant in the 



34 canyons.
