We review and describe the electromagnetic transmitters and receivers used to carry out
magnetotelluric and controlled source soundings in the marine environment. Academic …

We have developed a three‐axis electric field receiver designed to be towed behind a
marine electromagnetic transmitter for the purpose of mapping the electrical resistivity in the …

Electromagnetic methods are commonly employed in exploration for land-based mineral
deposits. A suite of airborne, land, and borehole electromagnetic techniques consisting of …

A low loss propagating electromagnetic wave is shown to exist at a gradual interface
between two lossy conductive media. The electromagnetic frequency range of this …

This study focuses on seafloor methane seep sites and their distribution in the northwestern
part of the German North Sea. Methane seepage is a common phenomenon along marine …

The magnetic susceptibility measured in alternating field can in general be resolved into a
component that is in-phase with the applied field and a component that is out-of-phase …

The magnetic susceptibility measured in alternating field can be resolved into a component
that is in-phase with applied field and a component that is out-of-phase. While the former …

Since the early discovery of a black-smoker complex in 1978 on the East Pacific Rise at 21°
N, speculations and expectations have been driven about the potential and perspectives of …

We present a series of processes for understanding and analysing controlled-source
electromagnetic (CSEM) responses for a conductive and permeable earth. To realize the …

It is demonstrated that a new kind of low-loss surface electromagnetic wave may propagate
along a planar surface inside a lossy medium if the medium permittivity changes …
