Integrated survey programs using several seismic reflection systems and side- 

 scan sonar in conjunction with grab- type and core sediment samples have been 

 successfully used in many environments. 



The Coastal Engineering Research Center (CERC) has been actively involved 

 for the past two decades in collecting and analyzing nearly 10,000 line miles 

 (16 093 kilometers) of geophysical profile data from 18 surveys over Atlantic, 

 Gulf of Mexico, and Pacific Continental Shelf areas as well as the Great Lakes. 

 The major objectives of this program have been to assess offshore sand and 

 gravel resources and describe the geological character and evolution of each 

 region. The geophysical equipment used, as well as specific techniques for 

 use of the equipment and interpretation of the data, is described herein.
