PREFACE 



This report is one o£ a continuing series which describes results of 

 the Inner Continental Shelf Sediment and Structure (ICONS) study. One 

 aspect of the ICONS study is locating and delineating offshore sand and 

 gravel deposits suitable for beach nourishment and restoration. The work 

 was carried out under the coastal processes program of the U.S. Army, 

 Coastal Engineering Rearch Center (CERC) . 



The report was prepared by Mr. S. Jeffress Williams, a CERC geologist j 

 under the supervision of Dr. David B. Duane, former Chief, Geological 

 Engineering Branch, and his successors, Dr. William R. James and Mr. Ralph 

 L. Rector. As part of the research program of the Engineering Development 

 Division, the ICONS study is londer the general supervision of Mr. George 

 M. Watts, Chief of the Division. The fieldwork (obtaining cores and seis- 

 mic reflection records) was carried out by Alpine Geophysical Associates, 

 Inc., under Contract No. DACW51-68-C-0044. 



Discussions with Mr. Edward C. Rhodehamel and others of the U.S. 

 Geological Survey(USGS) , Reston, Virginia, were helpful in deciphering 

 the Coastal Plain stratigraphy; Dr. Walter S. Newman of Queens College, 

 New York, provided guidance on use of the radiocarbon dates; Dr. John E. 

 Sanders of Columbia-Barnard College, New York; and Dr. Michael E. Field 

 of USGS (formerly with CERC) provided helpful reviews of the manuscript. 

 Appreciation is given to Mr. George Tirey of Woodward- Clyde-Sherard 

 Associates, and to the Testing Service Corporation for providing the 

 ancillary data. 



Microfilm copy of the CERC seismic data used in this study is stored 

 at the National Solar and Terrestrial Geophysical Data Center (NSTGDC) , 

 Rockville, Maryland 20852. Vibratory cores collected during the field 

 survey program are in a repository at the University of Texas, Arlington, 

 Texas 76010. Requests for information relative to these items should be 

 directed to NSTGDC or the University of Texas.
