1 DR. BOEHM: It looks like a reversed river delta. 



2 DR. BOTHNER: I see. 



3 DR. BOEHM: Whether that is episodic, whether it takes several big 



4 storms to move up silty clay material or whether that is the steady 



5 state phenomenon, I'm not sure. I'm certainly going far beyond what my 



6 data supports, but it just looks interesting. 



7 DR. VALENTINE: Were these hydrocarbon analyses conducted on the 



8 whole sample or just fine-grained portion or both, I wasn't quite clear 



9 on that? 



10 DR. BOEHM: That's the whole sample and generally the top 2 



11 centimeters of sediment. I don't believe we've done the size 



12 fractionation of sediments of purposes organics analyses. From other 



13 environments, Gulf of Maine and others that size fractionations have 



14 been done on, you do see the different compositions and different size 



15 fractions. 



16 So, putting all the pieces together, I think we are seeing 



17 composite types of materials, different types of source materials and 



18 different particle sizes. I'm pretty sure. 



19 DR. VALENTINE: If there are no further questions, thank you, 



20 Paul. 



21 Our next presentation will be by Dr. Jerry Neff of Battelle Ocean 



22 Sciences. He's going to talk about the "Potential Effects of Drilling 



23 Effluents on Marine Organisms."

27 DR. NEFF: The first so-called offshore oil well was drilled from 



28 a pier on the southern California coast in 1898, and in the last 90 



29 years, well over 25,000 additional offshore wells have been drilled in 



30 U.S. waters. 



31 Of those 25,000, approximately 10,000 or more are still in 



32 production. Now, the major concern associated with this offshore 



33 exploration and development, is that the operations themselves or 



34 discharges associated with these operations, whether they be intentional
