IV. SURVEY RESULTS 



A, General 



A significant advantage of a shipborne magnetic survey is 

 that bathjmietric measurements can be taken simultaneously with 

 the magnetic measurements. Direct comparison of magnetic and 

 bathymetric data relative to each other is thus possible, 

 irrespective of the certainty of the ship's true position. 



The data contained in this report provide useful infor- 

 mation relating to the geologic structure pattern %n this area. 

 These data can be correlated with similar information from 

 adjacent regions. Such correlation may yield clues leading 

 to a better understanding of the relationship between conti- 

 nents and ocean basins. 



B. Discussion of Data 



The magnetic field contour pattern in the survey area 

 (see Figure 2) contains a large, elongate, magnetic anomaly 

 on the western side. This anomaly has lineations corresponding 

 closely to those of the continental slope. On the eastern 

 side, the increasing complexity of the contour pattern suggests 

 the existence of a magnetic feature lying just outside the 

 survey area. Between these two features is a broad area 

 void of magnetic anomalies. 



In the survey area, the bathymetric data indicate that 

 the sea bottom has no topographic features capable of accounting
