3.1.2 Beals Island 



Beals Island constructed intertidal flat sediments were also finer grained than those 

 of the respective reference site. In this case however, the difference was less pronounced 

 than at Sheep Island. Beals Island constructed flat sediments contained approximately 75% 

 silts and clays, while reference area sediments had 30-50% fines (Figure 3-3). The same 

 apparent coarsening of sediments found in 1994 Sheep Island samples was present in the 

 Beals Island sediments. Likewise, by 1998 sediment texmre was similar to previous years. 

 Sediment organic content was also higher at the constructed flat than the reference site and 

 also declined between 1992 and 1994 (Figure 3-4).
