Picket, and Massey seamounts. These computations resulted in 
apparent magnetizations of 0.007 - 0.010 cgs units for these 
features. 
B. Zone Two Anomalies 
Relative to the Zone 1 anomalies, the features (fig. 4) 
over the Zone 2 seamounts are quite small (100-200 gammas). Although 
the seamounts in Zone 2 are at a deeper depth, this is not sufficient 
to explain the difference in anomaly magnitude. The Zone 2 sea- 
mounts are interpreted as representing an auxiliary fracture zone 
with a more acidic phase of volcanism than that of the Zone 1 
seamounts. It is noted that the bottom feature associated with the 
370-gamma anomaly located at 39°17'N, 64. 33'W (fig. 3) was found to 
have a peak sounding of 2380 fathoms. The magnitude of this anomaly 
is characteristic of the Zone 1 features. 
Upon comparing figure 4 with the bathymetry (fig. 3) it 
should be realized that figure 3 is based on rather sparse sounding 
information, and in some cases, bottom features may be displaced or 
missing entirely. Since each charted feature has a corresponding 
magnetic anomaly, it is probable that small seamounts or knolls 
exist in those areas displaying closed magnetic anomalies.
