1 Is that what we agreed to was the definition? 



2 A PARTICIPANT: A biological effect. 



3 MR, LANE: Directly related to OCS development, pile cuttings, 



4 produced water, operational discharges of hydrocarbons. It's not 50 



5 parts per million anymore from the oil and water separated but 48. Deck 



6 drainage, sewage discharges, accidental spills of oil, accidental 



7 releases by blow-out of gas and gas condensates, produced water with the 



8 same idea, the volume of these materials and their known toxicities, 



9 whether or not we can come up with a mechanism to get that toxic 



10 fraction down in contact with the communities. 



11 Space-use confl icts--the distribution of space, interference of 



12 the gear for fishing. We also talked about anchor chains and anchoring. 



13 We talked also about physical smothering. 



14 I guess the question on the floor now is: Does anyone have any 



15 additional issues, impact-producing agents, that they want to consider 



16 in evaluating the impacts to the biological communities in these 



17 canyons? 



18 DR. GRASSLE: What are those things written sideways? 



19 MR. LANE: Volume and toxicity over here. We just got as much as 



20 we could from Jerry on each of these. I don't know if it would help to 



21 go through each of these or not. 



22 DR. BOTHNER: How about one addition? Noise. I know there is 



23 data on that from the west coast and I don't know a thing about it, but 



24 if there are some of you who can comment, it would be interesting to 



25 hear. 



26 DR. HECKER: Fish are very sensitive to noise. It stresses out 



27 the poor little rock fish. What if they can't mate or something because 



28 they are freaked out? All I've heard is the noise perturbs them. 



29 DR. TEAL: That was seismic. 



30 DR. HECKER: Out and out seismic. Okay. 



31 DR. AURAND: In fact, MMS is the one who funded the study on that, 



32 lucky us. What we found was not so much that there was no recovery in 



33 terms of activity; what we found was a significant impact on
