FOREWORD 



The results of the survey described in this report are 

 considered to be of significance to both the Navy and the 

 scientific community. The region investigated is a transition 

 zone between a continental mass and a true oceanic basin. Geo- 

 physical investigations of such regions may lead to a better 

 understanding of the earth's major crustal features and their 

 origin. The use of geophysical exploration techniques such as 

 described here provide a means of deducing information about 

 the earth's deeper structures lying beyond the limits of 

 direct measurement.
