1 DR. GRASSLE: My feeling is that the accumulation would be very 



2 slow and based largely on the periods of spring blooming. 



3 DR. AURAND: Do you want me to change this to say benthic and 



4 water column effects are not expected, or finish the sentence which 



5 says, "For benthic effects to occur"? 



6 DR. GRASSLE: I think you should distinguish the two. 



7 DR. AURAND: Then help me finish the sentence, "For benthic 



8 effects to occur." 



9 DR. BOTHNER: Benthic effects are not expected, but would have the 



10 highest potential during periods of spring blooms. 



11 DR. GRASSLE: Actually, even that is not a worry. What you are 



12 worried about is the gradual accumulation, so accumulation on the 



13 bottom--gradual accumulation of hydrocarbons on the bottom is likely to 



14 occur over a period of years. 



15 DR. AURAND: And could occur in a localized area? 



16 DR. TEAL: I don't think it is likely to occur. These things are 



17 both fairly degradable but also very volatile. 



18 DR. RAY: You've got degradation going on the whole time you've 



19 got the--you know, in the stuff that's settling, you've got degradation 



20 going on the whole time. 



21 DR. TEAL: We're talking here about the light end of things. I 



22 can see closer to the shore-- 



23 DR. AURAND: In situations that I know of, they are marsh channels 



24 about 5 to 10 feet deep. You can find hydrocarbons in there. Jeff said 



25 in 35 feet of water and the other case was 9 feet of water. In 35 feet 

 25 and 9 feet of water, you could see hydrocarbons out to 100 meters. 



27 DR. GRASSLE: I haven't finished with the sentence--"could occur 



28 and should be monitored." 



29 DR. TEAL: I think that's too strong. I cannot agree with that. 



30 I think they are very unlikely. Then if you want to recommend that you 



31 monitor something that is very unlikely, why, that's okay, but I don't 



32 think you should.
