Abstract

To apply the controlled source time-domain electromagnetic method in the sea-floor exploration. The coplanar magnetic dipole-dipole (HZHZ) configuration is adopted in this paper. The sea-floor transient electromagnetic fields are analyzed based on the model of the seafloor and seawater double half spaces. The expressions of the transient magnetic field and electric field under the step function are calculated. The second time induced electromotive force curves are simulated based on the theory analysis. In order to distinguish the response curse form on the land and in the seafloor, the seawater effect is discussed.
