1 This goes from to 25,000 barrels over here. This is both mud 



2 and cuttings volumes. Just to maybe give you an indication of what 



3 these — these are the monitoring periods during the first period, the 



4 second period and the third period, where we collecting material in the 



5 traps, so you can see what we were doing there.

7 This is similar information, except this is mud only. You can see 



8 we had about 19,000 barrels of mud total. I am not going to say much 



9 about the currents except this. On the shelf, they were generally 



10 toward the southwest with a mean speed of between 10 and 21 centimeters 



11 per second. 



12 They were pretty constant. There was occasional, occasional 



13 reverses to the northeast, but not very many. Generally, it was pretty 



14 steady towards the southwest. The surface currents and bottom currents 



15 were pretty similar. 



16 In the canyon, we had some down canyon currents to the southeast, 



17 up to the north, the northeast, with a slight net flow up the canyon. 



18 The larger or higher magnitude current surges were down current, but 



19 there was a general slight trend upflow in the canyon, and they were 



20 completely decoupled from the shelf currents. There was no relationship 



21 we could see. 



22 Sediment analysis. It was mostly sand on the shelf. This is very 



23 similar, of course, to what we saw in the Mid-Atlantic Study. As you 



24 started going down in the canyon, the sand dropped and the silt and clay 



25 went up to the most, the deepest point in the canyon was only 3 percent 



26 sand, as opposed to about 90 percent sand up on the shelf. 



27 Silt/clay ratio, this is rough, but we had usually about twice as 



28 much silt as clay in most of the samples. It wasn't always the case, 



29 certainly, but roughly that. 



30 On the shelf, about 95 percent of the clay was equally divided 



31 between montmorillonite, alite, chloride, and kaolinite. In the canyon, 



32 there was less montmorillonite with a little bit more chloride and 



33 kaolinite. I don't know whether we took enough samples to generalize
