FOREWORD 



An important aspect of any oceanographic study is the delineation 

 and interpretation of structural features in the earth's crust. To 

 investigate these features in large oceanic areas masked by water 

 and sediments, geophysical techniques must be employed. This report 

 of a geomagnetic and bathymetric survey near the southern Bahama 

 Islands helps to clarify the major crustal trends in this structurally 

 complex area.
