First Using of a Circular Electric Dipole on a Water Surface

Abstract

Summary Geo electromagnetic soundings with traditional sources on the sea and lakes are associated with screening problems due to the strong conductor - the water layer. At sea, CSEM (Controlled Source Electromagnetic Method) (Constable, Srnka, 2007; Constable, 2010) is actively used. However, CSEM is limited in its application to great depths (more than 1000 m), large distances between the source and the receiver (up to 15 km). CSEM is difficult to apply under ice. To overcome the problems of marine electrical prospecting and successful work at sea, we propose to apply the method of Vertical Current Sounding (VECS).
