1 DR. GRASSLE: I guess what I am saying is that, if we use 14 



2 through 19, it really should be reduced to about a page of comments that 



3 are really pertinent. 



4 DR. MACIOLEK: Do you think we should go through this first 



5 section to see what we want to use in this final statement? We had some 



6 things to say about these tables? 



7 DR. GRASSLE: Oh, yes--to me the tables are very hard to 



8 understand, too, because the question is stated clearly and then the 



9 line-up of things that are relevant to the question are such in such 



10 cryptic form that it is almost impossible to know what people were 



11 thinking of. 



12 I guess everybody who is still here should try to put those into 



13 sentences--you know, a sentence that could be answered "yes" or "no." 



14 DR. VALENTINE: I think it would be helpful in the 



15 "Characteristics" section if we had some kind of overall definition of 



16 what we are talking about physically--in other words, are we talking 



17 about the canyons from the heads down to what I generally focus on, from 



18 the head down to what I call the mouth--where it crosses the shelf edge, 



19 say, at two hundred meters. 



20 DR. MACIOLEK: In other words, a definition-- 



21 DR. VALENTINE: Some canyons are very deep, you know, like 



22 Oceanographer, like--1300 meters deep at that point. Those are shallow. 



23 DR. GRASSLE: My understanding was that we were considering 



24 canyons including deep areas, right? Otherwise, we-- 



25 DR. MACIOLEK: Most of the discussions were on the shallower-- 



26 DR. GRASSLE: That is the area that is going to be potentially 



27 closest to the drilling activity, unless they start drilling out in 



28 deeper water. So I think we might want to clarify that one way or the 



29 other. 



30 I guess I think there should be two definitions. I think that 



31 right at the front of the report there should be a definition of a 



32 submarine canyon. That should be right on the second page of the 



33 report, because that says what all the part one stuff was about. That 



34 included a lot of consideration of the deeper parts.
