ABSTRACT (Coatlnua eat r*veram al^ ft neceaaary and Idenllfy by block number) 



Continuous seismic reflection and side-scan sonar geophysical equipment 

 were developed during and shortly after World War II primarily as military 

 tools, but their application to marine geology and oceanographic research 

 was quickly realized. In the past three decades electronics technology has 

 greatly improved the capability of geophysical equipment to function as 

 viable tools to decipher, in three dimensions, the geomorphology , subbottom 

 structure, and geological character of marine, estuarine, and lake regions.
