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 mm. 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 10 to the 6th power cubic yards of suitable sand is available within study limits. Author
