Abstract
Observations on the sea floor of naturally occurring electromagnetic signals reveal information on the deep structure of the Earth. Recent magnetotelluric soundings on the North Central Pacific have produced conductivity measurements which may relate to the partially molten zone or asthenosphere on which the well lubricated oceanic plates slide.
