Amundsen (Statoil ASA) SUMMARY In marine CSEM (controlled source electromagnetic) exploration and SBL (SeaBed Logging) the seabed subsurface is investigated by emitting low-frequency signals from a dipole source close to the seabed. The resulting electromagnetic (EM) field is recorded by receivers that usually sit on the seafloor. The main goal is to describe possible thin resistive layers within the conductive surroundings beneath the seabed. In the following various anisotropy effects in a stratified
