Figure 3-19. REMOTS® image obtained at USCGA Station 1 OOSE, Replicate A displaying 

 two Chaetopterus sp. constructed tubes, or potentially the two exposed ends of 

 a single U-shaped tube 42 



Figure 3-20. REMOTS® sediment-profile photographs collected at WEST REF Station 



WR-5, Replicates B and D displaying small clumps of mussels actively filter- 

 feeding at the sediment-water interface 44 



Figure 4-1 . A series of REMOTS® sediment-profile photography images collected at 

 NL-91 and D/S Mound Complex Station lOON showing changes in 

 sediment composition between surveys, indicating the deposition of 

 supplemental CDM 49 



Figure 4-2. REMOTS® sediment-profile images collected over the NL-91 and D/S 

 Mound Complex Station 400E during the (A) July 1 998 survey and (B) 

 August 2000 survey showing the apparent improvement of benthic habitat 

 conditions 52 



Figure 4-3. Map showing the distribution of supplemental CDM at the NL-9 1 and 



D/S Moimd Complex based on a combination of the 1997-2000 bathymetric 

 depth difference results and the August 2000 REMOTS® results (green 

 contour line) 53 



Figure 4-4. Seawolf Mound depth difference comparisons based on sequential 



bathymetric surveys displaying changes in disposal mound consolidation 



rates for (A) 1996 to 1997 (first year) versus (B) 1997 to 1998 



(second year) 54 



Figure 4-5 . REMOTS® sediment-profile images obtained at the USCGA Mound 

 Station CTR in (A) September 1995 and (B) August 2000 displaying 

 changes in appearance after organic material is consumed by benthic 

 infauna or oxidation 60
