MATERIALS AND METHODS 

 Sampling sites 



A total of seven different shore zone sites have been sampled at 

 one time or another since 1969. They were designated GN, BL, SP, IN, 

 JC, WP and SS and are shown in Fig. 1. 



The beach at Giants Neck (GN) has a southerly exposure but is 

 protected by Black Point, Giants Neck, and some offshore islands. The 

 bottom consists of medium to coarse sand with some large emergent rocks. 

 Detached algae and detritus are usually present in the shore zone. The 

 Giants Neck site, approximately three miles west of the power plant, is 

 removed from the zone of probable MNPS impact and is considered a control 

 site. 



The Black Point site (BL) near Crescent Beach has an easterly 

 exposure with moderate wave action. The bottom is of medium-grained 

 sand, and there is virtually no attached vegetation in the shore zone, 

 although some detached plant material is present in the seining area. 



The site at Sandy Point (SP) , in the Niantic River, is subjected to 

 the least amount of wave action. The bottom is of medium-sized sand 

 grains and occasionally there is a great deal of deteached plant life in 

 the sampling area.
