Other magnetic lineations present in the area may be seen 

 most clearly on the Residual Magnetic Intensity Contour Chart, 

 Figure 5. (The negative residuals on this chart have been shaded 

 to aid in illustrating the trends.) In the northwest comer of 

 the survey area, a llneation occurs with a strike parallel to 

 that of the major magnetic llneation. South of the major 

 feature, the llneated patterns are not as pronounced and occur 

 at angles of 35°-45° to the main feature. Nearly all of the 

 large seamounts in the area are located along these southern 

 lineations. Strongly negative magnetic anomalies occur over 

 these seamounts--more negative than should be expected at this 

 geomagnetic inclination of 33° north. 



The track charts, magnetic contour charts, and bathymetric 

 contour charts of the eight development survey areas are pre- 

 sented in Figures 14 through 37. Preliminary analysis of 

 magnetic data over the seamounts was performed utilizing a com- 

 puter program originated by Victor Vacquier of the Scripps Insti- 

 tution of Oceanography. With this program, estimates of the 

 intensity and direction of magnetic polarization of the seamounts 

 in development areas 1, 2, and 4 were determined. These compu- 

 tations have shown that the three seamounts analyzed are reversely 

 magnetized. Analysis of the other development areas is planned. 



Examination of the magnetic and bathymetric data from this 

 ■survey suggests that a major geologic fault occurs along the 

 main magnetic llneation. The magnetic patterns north of this
