1 DR. AURAND: Certainly, from our point of view, if that were to 



2 lead to the list of limitations that that would usually lead to, we 



3 would want to make sure that it was restricted to those limitations 



4 which appear to have bearing on the ability of the group to draw 



5 conclusions and recommendations. 



6 That list may be shorter than this list or it may include some 



7 things we haven't thought of yet, so I think that is an appropriate 



8 thing to do. 



9 DR. BUTMAN: Good. Well, that concludes my list. 



10 DR. AURAND: If I read the intent of all of this properly, we need 



11 to go on now to the biology of it. Did we have a volunteer? 



12 DR. MACIOLEK: I volunteered Barbara. 



13 DR. AURAND: We need to do that before lunch and then come back 



14 after lunch and start to try to put this together. Is that where we 



15 ended up? That's my understanding of where we ended up. 



16 DR. HECKER: I am not as well organized as Brad. 



17 DR. AURAND: Few of us appear to be.

19 BIOLOGICAL PROCESSES--DR. BARBARA HECKER, DISCUSSION CHAIR 

 20 



21 DR. HECKER: Basically, I tried to do the same thing that Brad did 



22 with regard to some of the biological characteristics. What I have come 



23 up with is the biological characteristics of canyon populations. 



24 Do they have a higher biomass for the megafauna? Yes. For the 



25 infauna? Yes. Higher diversity for the megafauna? Yes. For the 



26 infauna? No. Do we feel that we may have finely mediated pollutant 



27 concentrations due to feeding strategies for the megafauna? Yes. For 



28 the infauna? No. 



29 Nancy said that they looked for filter feeders, differences in 



30 filter feeding, differences in surficial fine deposit feeders. They did 



31 not find those differences in the canyon stations. 



32 Then the question is: Were the canyonheads nurseries for 



33 commercial populations? Yes. For commercial species? Yes. Were there
