i68 Alaskan Science Conference 



These three observatories may be expected to contribute 

 materially to the understanding of magnetic phenomena, not 

 alone in the Arctic but in lower latitudes as well. Their work 

 is correlated closely with other geophysical activities in the 

 area, and it goes without saying that the records they produce 

 are invaluable in the reduction of all magnetic field work in 

 Alaska as well as in ionospheric studies. In the aggregate, we see 

 that Alaskan magnetic work merits vigorous support, both for 

 its fundamental import as a segment of Earth science, and for 

 its vital contributions to practical affairs.
