PREFACE 



This report is one of a continuing series which describes results of the Coastal Engineering 

 Research Center (CERC) Inner Continental Shelf Sediment and Structure (ICONS) Study. 

 One aspect of the ICONS program is locating and delineating offshore sand and gravel 

 deposits suitable for beach nourishment and restoration. 



S. Jeffress Williams, a CERC geologist, prepared the report with the assistance and 

 supervision of David B. Duane, Chief, Geology Branch. As part of the research program of 

 the Engineering Development Division the ICONS Study is under the general supervision of 

 Mr. George M. Watts, Chief of the Division. The field work involving coring and continuous 

 seismic profiling was carried out by Alpine Geophysical Associates, Inc., under contracts 

 DA-36-109-CIVENG-64-193, and DACW-51-68-C-0044. 



Discussions with Mr. Michael E. Field and Mr. Edward P. Meisburger of the CERC staff 

 were helpful during interpretation of the data. Mrs. Patricia Blackwelder examined sediment 

 samples by electron microscope which aided in interpretation of paleoenvironments. 



Microfilm copy of all seismic data used in this study are stored at the National Solar and 

 Terrestrial Geophysical Data Center (NSTGDC), Rockville, Maryland 20852. Vibratory 

 cores collected during the field program are in custody of the National Oceanic and 

 Atmospheric Administration (NOAA), Rockville, Maryland 30852. Requests for 

 information relative to these items should be directed to NSTGDC or NOAA.
