 (MCDA buoy), and Morris Cove Reference Area, relative to the 

 East Haven shoreline 3

borrow pit 16 



Figure 3-2. Side-scan sonar image displaying several acoustically detectable 



bottom features within the Morris Cove borrow pit in close proximity 



to the MCDA buoy position 17 



Figure 3-3. Map showing the average thickness of the dredged material layer 



observed in replicate sediment profile images at each station 19 



Figure 3-4. REMOTS® image from station lOOSW within the Morris Cove borrow 

 pit, showing a layer of fine-grained dredged material extending from the 

 sediment- water interface to below the imaging depth of the camera (i.e., 

 dredged material greater than penetration) 20 



Figure 3-5. REMOTS® images from stations REF4 (left) and REF5 (right) 



illustrating the relatively soft, fine-grained sediment (grain size major 

 mode of > 4 phi) which characterized the reference area stations 21
