The sediment cores were obtained with the use of the PVC version of the University 

 of Rhode Island/Marine Geomechanics Laboratory (URI/MGL) large-diameter gravity 

 corer (LGC; Figure 2-4; Silva et al. 1996). The core barrel consists of a 3 m (10 ft) 

 section of Schedule 40 PVC piping (10.2 cm or 4.0 I.D.) and includes a nose cone and 

 core catcher on the end. 



All cores were transported back to the URI laboratory facilities and refrigerated 

 during storage. The CLIS sediment cores were processed to obtain overall sediment 

 composition, bulk density, water content, grain size, Atterberg Limits, specific gravity, 

 and shear strength (Silva et al. 1996). A detailed description of the methods used for the 

 analysis of sediment cores GC-1 through GC-11 will be included in a report submitted by 

 Armand J. Silva, P.E., of Geotechnical Consulting Engineers.
