1 We don't have to justify doing that and we don't have to justify 



2 the fact that, since this is a different sort of a physical and 



3 biological situation that the conclusions are going to be somewhat 



4 different. 



5 DR. BUTMAN: I like that approach. Let's just take this out of 



6 here. 



7 DR. BOTHNER: Brad, I am tempted to say one other thing to you. 



8 You just said that sometimes the chemical effects are limited to a 



9 kilometer or two. 



10 In fact, we can measure some signals as much as 60 kilometers away 



11 from the drilling region on Georges Bank. It just depends on how hard 



12 you want to look at it. There is nobody I think that would make the 



13 case that--well, it is difficult to predict any effects, certainly, 



14 beyond a few kilometers. 



15 The fact that you can find the chemistry a good deal farther than 



16 that has been documented. 



17 DR. BUTMAN: Okay. I wanted to somehow convey--maybe it is the 



18 special characteristics of the canyon, but this is the first case where 



19 we have talked about a confined area. All the other studies have been 



20 done--on discharges--for the open environments. 



21 DR. TEAL: All the ones in the open ocean, but certainly that's 



22 not true elsewhere, is it? We've got lots of confined areas and made a 



23 big point of it in some cases. 



24 DR. BUTMAN: That's true. 



25 DR. TEAL: In produced water discharges in coastal lagoons, the 



26 whole point there is that you've got a confined area and you have to 



27 treat that differently than you treat produced water discharge along the 



28 open coast. I still think that it is a given that we look at this in a 



29 special way because it is a special environment. 



30 DR. BUTMAN: I think instead of having a lot of discussion on this 



31 list of limitations, that might be the last thing we do. That's a 



32 proposed list, but it might be more important to flesh that out after we 



33 discuss the specific problem.
