1 AFTERNOON SESSION

3 DR. GRASSLE: Okay, will you read for the record, Mike? 



4 DR. BOTHNER: For the record, "Data on vertical particle flux, 



5 sediment transport and rates of sediment accumulation (processes which 



5 influence the fate and effects of contaminants) are needed in all of the 



7 canyons of the North Atlantic area." 



8 DR. KRAEUTER: No, I do not think we can say "all." 



9 DR. BOTHNER: "The lack of this basic information inhibits our 



10 ability to make definitive conclusions." 



11 DR. KRAEUTER: I think "all" is overkill. It would be nice. 



12 DR. GRASSLE: There was passed out a page 25d which was our just 



13 agreed version of "H"--oil spills and blowouts. I made one tiny change 



14 in the end of the paragraph where there are two "ifs" and so I got rid 



15 of the second "if." 



16 That brings us to "Needs" "C." 



17 DR. VALENTINE: I have modified that. I have got a version I 



18 would like to pass out. 



19 I tried to make this a little bit more specific--the physical 



20 information. You can see how I changed that. I expanded the needs and 



21 why we need the information. 



22 It seems like we have somewhat of a good foundation for 



23 understanding what is happening in these canyons, primarily from two 



24 canyons, but with less information from parts of other canyons. There 



25 seem to be certain patterns and certain processes dominating certain 



26 areas. 



27 We really need more information from a variety of the canyon types 



28 to put it together and really make it useful for predicting any future 



29 impacts. 



30 DR. AURAND: Can I offer a suggestion for the last sentence? 



31 DR. VALENTINE: Sure. 



32 DR. AURAND: "Comprehensive studies in a variety of canyon types 



33 would improve the ability to predict--" or something like that.
