1 I'll show you some sections across the canyon at those five red 



2 lines. It's essentially V-shaped, definitely the V gets deeper as you 



3 go deeper in the canyon. These are now five sections in profile near 



4 the head at 500 meters and at 1,500 meters. 



5 The canyon walls in the deeper part of the canyon are about 20 



6 degrees, they're only about 10 degrees at the shallower end. The walls 



7 in the canyon are vertical in the canyon are vertical in a number of 



8 places. This is sort of an average slope, and in many places it is very 



9 step-like and blocky as you go up the slope. 



10 So, here again when we talk about environments in the canyon, we 



11 have to think about both the canyon floor, which I showed you before, 



12 the sediment texture along the floor, but also the canyon walls which 



13 change in character from the deeper parts of the canyon to the shallower 



14 parts of the canyon. 



15 I'd like to show you some highlights from the moored-array 



16 experiment. This shows the location of all the current meter moorings 



17 which we deployed in the canyon during the 2-year period. They weren't 



18 all deployed at the same time. We actually had five deployments of 



19 current meters, each for 3 to 6 months long. 



20 We maintained four stations as long-term stations, one on the 



21 shelf, one on the head of the canyon at 300 meters, one at 500 meters, 



22 and one on the continental slope. 



23 The objective of this was to look at the circulation pattern both 



24 within the canyon, along the canyon axis, across the canyon axis at 



25 several locations, on the adjacent shelf around the head of the canyon 



26 and on the adjacent slope both upstream and downstream. 



27 In addition to the moored-array experiment which we conducted in 



28 Lydonia Canyon, we made three deployments in Oceanographer Canyon to try 



29 to compare those two. 



30 I hate to show spectra to this audience, but this is an attempt to 



31 show the difference between the flows, the statistics of the flow on the 



32 shelf, and along the shelf and slope and along the canyon axis. 



33 LCA is essentially our shelf station, LCI is the station on the 



34 slope. These three stations are progressively from shallow to deep in
