LIST OF FIGURES 



Figure 1-1. Results of side-scan interpretation of the BBDS in 

 1981 (from Germano et al . . 1989) . The surveyed 

 area was 2.8 km 2 in 1981 compared with 0.8 km 2 in 

 the March 1990 survey.

 for benthic and sediment analyses at the BBDS, 

 March 1990.

Figure 3-4. A REMOTS* photograph from BBDS reference area 3 

 showing an ambient bottom of fine-grained material 

 and a Stage III assemblage. 



Figure 3-5. A REMOTS* photograph of rippled sandy bottom at the 

 BBDS center. Successional stage is indeterminate. 



Figure 3-6. A REMOTS* photograph from BBDS reference area 2 

 showing the superposition of sand over mud. 



Figure 3-7. A REMOTS* photograph from BBDS station 19 which had 

 a surface layer of mud over sand related to the 

 presence of dredged material. 



Figure 3-8. A REMOTS* photograph from BBDS stations 17 and 32 

 showing the deposition of sand over mud possibly 

 related to disposal events.

 boundary roughness for disposal stations at BBDS, 

 March 1990.

 boundary roughness for reference stations at BBDS, 

 March 1990.
