PREFACE 



This report is one of a series which describe the results of the 

 Inner Continental Shelf Sediment and Structure (ICONS) program. The 

 primary objective of the ICONS study is locating and delineating offshore 

 sand and gravel deposits suitable for beach nourishment and restoration. 

 This work was carried out under the coastal processes research program 

 of the U.S. Army Coastal Engineering Research Center (CERC). 



This report was prepared by Michael E. Field, formerly with CERC 

 and presently with the U.S. Geological Survey (USGS), under the general 

 supervision of D.B. Duane and W.R. James, former Chiefs of the Geological 

 Engineering Branch at CERC. As part of the overall research program of 

 the Engineering Development Division, the ICONS study was under the gen- 

 eral supervision of G.M. Watts, former Chief of the Division. 



The author acknowledges the following individuals at CERC who provided 

 assistance in various aspects of this study: W.R. James, E.P. Meisburger, 

 R.K. Schwartz, A.E. DeWall, S.J. Williams, and E. Nelson. H.D. Palmer 

 (Dames § Moore, Inc.) assisted in the 1974 data collection phase, J.M. 

 Wiegle (USGS) assisted in correlating certain aspects of the seismic 

 data with onshore geology, and J.W. Pierce (Smithsonian Institution) 

 offered criticisms on some of the ideas presented. 



The data and much of the information included in this report provided 

 the basis for Field's dissertation submitted to George Washington Univer- 

 sity in partial fulfillment of doctoral requirements (Field, 1976). 



Microfilm of all seismic data is stored at the National Solar and 

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

 Cores collected during the field survey program are in a repository at 

 the University of Texas, Arlington, Texas 76010, under agreement with 

 CERC. Requests for information relative to these items should be directed 

 to NSTGDC or the University of Texas.
