1 DR. VALENTINE: Oh, yes. 



2 DR. HECKER: Heezen doesn't really indent the slope. 



3 DR. VALENTINE: Indenting the shelf. 



4 DR. HECKER: Indenting the shelf, yes. 



5 DR. COOPER: File Bottom and Heel Tapper are really more like 



6 gulleys. 



7 DR. VALENTINE: File Bottom does not invade the shelf bank, but 



8 there are 11 or 12 canyons, which I showed--Heel Tapper being one of 



9 them--which does, but it is really just slope environment. 



10 If somebody is setting aside canyon areas and this is a named 



11 canyon and it is set aside, when really it is not like what we think of 



12 as canyons--Oceanographer, Lydonia, that sort of thing--we don't have 



13 enough information on it. 



14 Nobody has studied these smaller ones to any extent that I know 



15 of, so we really don't know much about them. 



16 DR. MACIOLEK: We have what we have the "gully/non-gully" 



17 comparison, but there weren't any names. 



18 DR. VALENTINE: Those are probably not areas that are considered 



19 "canyons." 



20 DR. MACIOLEK: No, they wouldn't be at all. 



21 DR. MACIOLEK: Your point goes back to Brad's question about to 



22 how many canyons can we apply that characterization and it also comes 



23 back to Brad's list of limitations on the data because we haven't 



24 studied all of the major canyons. 



25 DR. VALENTINE: I made one dive in this Heel Tapper Canyon for the 



26 purpose of comparing sediment texture and sedimentary processes and I 



27 just had one dive, so I went up the so-called axis of this canyon, which 



28 is really not very well defined. It looks just like the slope. That's 



29 just one observation. 



30 So, I mean here is an area that we probably should address, I 



31 should think. 



32 DR. COOPER: I think Page has got an excellent point here and we 



33 probably should have jumped on this sooner. But I think that we've had 



34 enough experience, even though some of these canyons may have received 



229
