1 These traps were put on the moorings and on the tripods to collect 



2 material for future analysis. We used different shapes and sizes to 



3 collect material where we expected different fluxes. 



4 Although no one knows what the efficiency of sediment traps are in 



5 areas where high currents exist, we've gotten around that problem in a 



6 relative sense by conducting experiments where all of the trap results 



7 are compared to the smaller two-trap, which was more generally used. 



8 So, our results from area to area can be compared in a relative 



9 sense. A photograph showing the instrument package that was used in the 



10 deeper parts of the slopes is shown here. This is the current meter 



11 that was positioned a few meters above the bottom. 



12 We had a benthos camera that took pictures of the bottom. Some of 



13 Brad's data for the transmusometer [phonetic], the beam attenuation 



14 recording continuously on an instrument located here and here's our part 



15 of the puzzle here, it's a sediment trap that collects some of the 



16 material that's in suspension. 



17 The first deployment in Lydonia Canyon had the best coverage, so 



18 I'd like to show you what we see on an aerial basis in that region. 



19 This map diagram shows the flux in grams/meter^ per day of the 



20 trap sediment over the whole study area. The black dots represent 



21 locations of the moorings and more impressive, the diagrams here, the 



22 histogram showing the colored bars represent the flux of the sediment 



23 collected by the traps at various heights above the bottom. 



24 In this particular location you see that 5 meters above the 



25 bottom, between 20 and 26, and the green represents above the bottom. 



26 The main points in this particular diagram are that Lydonia Canyon 



27 at the head, in about a little less than 300 meters of water, you have 



28 the greatest flux of material collected by the traps. That was 



29 consistent over all five deployments. 



30 As you move away from the bottom, higher up into the water column, 



31 there is a dramatic increase in the collected material. This points up 



32 to the fact that what we're really collecting at the bottom is the 



33 source of this material collected.
