Figure 13. Continental shelf profiles taken between Virginia Beach, Va., 

 and Hatteras Island, N. C, to 30 km from shore (the averaged profile is 

 a solid line; dotted profile is a mathematical fit to the average pro- 

 file) (after Everts 1976) 



36. Bathymety further seaward on the continental shelf reflects both 

 past and present processes. In the study area, the shelf is a broad sand plain 

 molded into north-south-trending sand ridges and troughs of up to 10-m relief 

 (Swift et al. 1978a, p 21). Two shelf-valley complexes were generated by the 

 landward displacement of the Chesapeake Bay and Albemarle Sound estuaries as 

 sea level rose in the Holocene epoch. Each complex has left an imprint on the 

 inner shelf: one lies seaward of the shoreface of Virginia Beach, Virginia, 

 and the other off Nags Head, North Carolina (Swift et al. 1978a, p 20).
