  <dc:description>&lt;p&gt;&lt;span&gt;To investigate the effect of&amp;nbsp;&lt;/span&gt;anomalies&lt;span&gt;&amp;nbsp;in the Earth's&amp;nbsp;&lt;/span&gt;magnetic&lt;span&gt;&amp;nbsp;field&amp;nbsp;&lt;/span&gt;at&lt;span&gt;&amp;nbsp;&lt;/span&gt;high&lt;span&gt;&amp;nbsp;&lt;/span&gt;altitudes&lt;span&gt;, aeromagnetic maps of two representative areas showing isanomalic curves for total intensity are projected to levels of 10 and 20 miles above the surface of a plane Earth. The projections are accomplished by numerical computations and by use of a&amp;nbsp;&lt;/span&gt;magnetic&lt;span&gt;‐field projecting machine&amp;nbsp;&lt;/span&gt;at&lt;span&gt;&amp;nbsp;the Naval Ordnance Laboratory. It is found that&amp;nbsp;&lt;/span&gt;anomalies&lt;span&gt;&amp;nbsp;of 500 gammas near the surface of the Earth, in merging into neighboring&amp;nbsp;&lt;/span&gt;anomalies&lt;span&gt;, may produce effects of 100 gammas or more&amp;nbsp;&lt;/span&gt;at&lt;span&gt;&amp;nbsp;an&amp;nbsp;&lt;/span&gt;altitude&lt;span&gt;&amp;nbsp;of 20 miles.&lt;/span&gt;&lt;/p&gt;</dc:description>
