Figure 3-59. Benthic "process" map which indicates the 

 distribution and thickness (cm) of apparent dredged 

 material at the Norwalk disposal mound in July 1986. 

 Hatched area delimits the extent of apparent dredged 

 material. Symbols are defined as follows: 



# = Apparent dredged material thickness (cm) 



#+ = Apparent dredged material thicker than REMOTS* 

 window penetration 



NDM = No apparent dredged material 



S/M = Sand over mud stratigraphy 



SHELL = Shell lag deposit 



RS = Reduced sediment near the sediment-water 

 interface 



CH* = Methane gas present
