BARN ISLAND #1 





BARN ISLAND #3 



Figure 3. Labelled cores from sediments of Barn Island Marsh, Connecticut (Niering et 

 al. 1977). Core 1 site began with Panicum (bottom layer), probably on the edge of the 

 marsh, which was replaced by typical marsh grasses as sea level rose. After the 1938 

 hurricane, indicated by the uppermost sand layer, the vegetation changed again. The 

 site of core 3 began as a Phragmites marsh in brackish water which was replaced by 

 Spartina as sea level rose.
