t. ABSTRACT 



The Inner Continental Shelf off eastern Florida was surveyed by CERC to obtain 

 information on bottom morphology and sediments, subbottom structure, and sand 

 deposits suitable for restoration of nearby beaches. Primary survey data consists 

 of seismic reflection profiles and sediment cores. This report covers that part of 

 the survey area comprising the inner Shelf between Palm Beach and Cape Kennedy. 



Sediment on beaches adjacent to the study area consists of quartzose sand and 

 shell fragments. Median size of midtide samples generally lies in the range between 

 0.3 to 0.5 ram. (1.74 to 1.0 phi) diameter. 



The Shelf in the study area is a submerged sedimentary plain of low relief. 

 Ridge- like shoals generally of medium-to-coarse (0.25 to 1.0 mm.) calcareous sand 

 resting on the seaward dipping subbottom strata contain material suitable for beach 

 restoration. A minimum volume of 92.2 x I06 cubic yards of suitable sand is avail- 

 able within study limits.
