ABSTRACT 



The entrance of the Chesapeake Bay and the Atlantic Ocean in the vicinity of Cape 

 Charles and Cape Henry were surveyed to study the bottom morphology and sediments, 

 and subbottom structure, in an effort to locate suitable sand deposits in volumes 

 great enough to economically restore and periodically nourish the shore. Seismic 

 reflection profiles and sediment cores were the basis for the study. Field and 

 laboratory techniques used for the profiles and sediment obtained from the sea 

 floor in lower bay and ocean are presented. Most of the study area is less than 

 35 feet deep; distribution of shallow bay and inshore terraces and deeper water are 

 shown in the figures. The study included analyses of borings taken along the route 

 of the Chesapeake Bay Bridge Tunnel by the Bridge Commission in 1960 and 1961. Cores 

 obtained for a dredging study by the Norfolk District, Corps of Engineers, 1970, were 

 made available and were used in the study.
