 bars in Florida. Florida State Geological Survey Bulletin 7:7-32. 



This article summarizes the results of studies conducted to de- 

 termine whether one of the best defined raised beaches, that bor- 

 dering the Pensacola terrace, has been subjected to differential 

 uplift, or has remained at a uniform altitude above sea level 

 throughout the area studied. The article includes a discussion 

 of islands, dunes, sand ridges, and offshore bars on the Atlantic 

 coast, but none are identified by name.
