• Map the extent of fresh capping dredged material over the NL-91 and D/S 

 mound complex. 



Analyses of data collected during the July 1998 field effort at the NLDS were used 

 to test hypotheses consistent with the DAMOS Tiered Monitoring Protocols (Germano et 

 al. 1994). First, a healthy benthic assemblage with Stage III individuals were expected 

 over the older areas of the NL-91 and D/S mound complex. Where new capping material 

 had been placed over the mound complex, Stage I and II organisms were predicted to be 

 common, representing the early phase of recolonization. Finally, a new layer of capping 

 dredged material was expected to be detected in REMOTS® stations over the northern and 

 possibly western region of the NL-91 and D/S mound complex. 



1.3.5 NLDS Northern Region 



In 1996, DAMOS adopted the NLDS programmatic EIS boundaries which resulted 

 in a northerly shift of the NLDS boundaries. A baseline characterization of the seafloor 

 between latitudes 41° 16.606' N and 41° 16.806' N and longitudes 72° 03.907' W and 

 72° 05.234' W was required to ensure adequate comparisons with future datasets (Figure 

 1-2). The 1997 survey over this 0.685 km 2 area was conducted to provide detailed 

 information pertaining to bafhymetric features and sedimentary characteristics within the 

 Northern Region. In addition, REMOTS® data were collected over the Northern Region of 

 NLDS to provide baseline characterization of the sediments prior to dredged material 

 disposal.
