Abstract

WITH the development of new techniques and a growing interest in the electrical conductivity of the Earth, the examination of electromagnetic induction in certain types of environment on the Earth's surface has been considerable. Of particular interest is the anomalously large ratio of the variations in the vertical and horizontal geomagnetic components observed near the coast during micropulsation and bay type disturbances. The region of enhancement extends to the landward side of the coast a distance of the order of 100 km, but the extent seaward is at present very poorly known.
