1 It was a comparison like that. So, needless to say, it would 



2 cause concern in a study when we're worried about benthic changes. 



3 In this particular study we had one of those wonderful design-by- 



4 committee studies which never make logical sense, so this was not only a 



5 bullet pattern, but part of it was driven by--out of logic one came 



6 because it was regulation. So, we got 300 foot, 400 foot, and then we 



7 go to 500 meters and 1,000 meters. 



8 So, as to the logic of these distances, I really can't defend any 



9 of them. This is the basic pattern from which this data was generated. 



10 This one view graph has got more information than you'd ever want 



11 to look at at once, but it's really kind of good. Here are you 



12 different metals, aluminum, arsenic, barium, cadmium, chromium, copper, 



13 iron, lead, mercury, zinc. 



14 What you see here we call this our "lollipop diagram." You're 



15 seeing the four cruises, pre-drill ing, right after drilling starts, the 



16 third one you'll see is right after drilling stopped, and then the last 



17 one here is about 8 or 9 months after drilling. 



18 These are each transects. This is 300 west, 300 south, 300 east. 



19 So, each of these are the transect and so what you are able to see is 



20 before drilling, right after it started, right after drilling ended, in 



21 that 8 or 9 months, whatever it was, at the end of it. 



22 So, you are seeing here on this transect the pre-drill ing level, a 



23 pretty good spike at 300 feet, soon after drilling began it dropped off 



24 a little bit and then that 8 or 9 months post-drilling. 



25 So you can see the trends. All this data you are seeing here with 



26 these trends like this is whole fraction, bulk sediment. 



27 Now let's look at fine fraction. In fine fraction you see a lot 



28 less deviation in the concentrations. In barium, which is our key 



29 tracer again, right here at the post-drilling point it really spikes, as 



30 you get a little further out it's coming down. 



31 Cadmium, you saw an early spike in here, in close, as you get a 



32 little further out it's lower. Chromium is pretty flat, an interesting 



33 spike in copper here, 8 or 9 months after the fact. Don't ask me why 



34 because I don't know.
