1 we're measuring currents at a fixed location on basically an Eulerian 



2 current measurement. On such a complex environment, it's not clear 



3 whether the particles are actually, over the long term, actually 



4 following the Eulerian current field. 



5 That aside, there is strong evidence from all the measurements 



6 we've made along the axis of a convergence toward the head, that there 



7 is down-canyon transport in some locations, and up-canyon transport in 



8 the others. 



9 If you look at the--go back to the sediment texture distribution, 



10 again where we found this pocket or increased levels of fine-grained 



11 sediments near the head, we find that the measurements show up-canyon 



12 transport or convergence toward that "deposit." 



13 I think it's a little difficult for some of us to accept up-canyon 



14 transport, but this data at least suggests that. 



15 If you want to compare Lydonia Canyon to Oceanographer Canyon, 



16 these are the results, the measurements from the Oceanographer Canyon. 



17 Here were only measured at two stations, one at about 300 meters and one 



18 at about 550 meters. 



19 At both of those stations we saw net down-canyon flow. I think as 



20 Page will discuss later, Oceanographer is very different in sediment 



21 texture and topographically from Lydonia. 



22 It's a very smooth-walled canyon, there's very course-grained 



23 sediments along the entire axis, and here we saw net down-canyon 



24 transport. We didn't see a suggestion, at least at mid-depths, of up- 



25 canyon flow. 



26 I'd like to compare the flows in the canyons to the flow on the 



27 continental shelf. In a recent paper by Chinadi, et al [phonetic], they 



28 summarized the statistics of flow from a number of different experiments 



29 along the continental shelf; the Lydonia Canyon Experiment, the North 



30 Atlantic Slope Experiment, the SEEP Experiment, MASARS Experiment, and 



31 the Baltimore Canyon Experiment. 



32 They separated the flow into two categories. The flow greater 



33 than 20 cm/sec, which we took as indicative of erosional environments
