V. SUMMARY OF FINDINGS 



Magnetic measurements across the continental slope and 

 adjacent deepwater area off the east coast of the United States 

 revealed the presence of an elongate anomaly of a few hundred 

 gammas amplitude. This anomaly has a lineation corresponding 

 closely, but not exactly, with that of the continental slope. 

 Depth estimates made on this anomaly are in reasonable agree- 

 ment with seismic depths to crystalline rocks. This agreement 

 suggests that the anomaly is caused by contrasts in intensity 

 of magnetic polarization within the basement. 



The center of the survey area is void of magnetic features. 

 However, small, broad anomalies occur about 60-80 miles east 

 of the continental slope. Bathymetric data revealed no 

 topographic features capable of accounting for these anomalies. 

 Consequently, these anomalies may be reflections of some type 

 of deep-seated lithologic contrast.
