THE TRANSMISSION OF GEOMAGNETIC DISTURBANCES.

Abstract

The research has been mainly concerned with a theoretical investigation of geomagnetic disturbances. The chief interest has been geomagnetic micropulsations with periods from a few minutes down to a fraction of a second. Particular attention has been paid to those of irregular type and to hydromagnetic emissions (regular pulsations with periods around one second). A permanent field station has been in operation for more than 5 years - from June 1962 to December 1967. Additional field stations were maintained at Suffield Experimental Station, Alberta; Great Whale River, Quebec; Byrd Station, Antarctica - these are still in operation. In addition a number of field operations were carried out to determine the effect on micropulsations of local geology and proximity of the observing station to the sea. Large period magnetic disturbances have been used to carry out a programme of geomagnetic depth sounding - to determine possible structures and electrical conductivities. (Author)
