About 800 square miles of the Atlantic Inner Continental Shelf off Long 

 Island, New York, were studied by CERC to obtain information on the sea floor 

 morphology, sediment distribution, and shallow subbottom stratigraphy and 

 structure. This information is used for delineating sand and gravel resources 

 and deciphering shelf geologic history. Basic survey data by CERC consist of 

 735 miles of high-resolution continuous seismic profiles and 70 vibratory 

 cores; additional data were available from 82 sediment cores and 225 miles of
