A system to perform a marine subterranean survey includes at least one vertical electromagnetic (EM) source and at least one EM receiver to measure a response of a subterranean structure that is responsive to EM signals produced by the vertical EM source. At least one tow cable is used to tow the EM source and EM receiver through a body of water. L'invention concerne un système pour une exploration souterraine marine, qui comprend au moins une source électromagnétique verticale (EM) et au moins un récepteur EM afin de mesurer une réponse d'une structure souterraine sensible aux signaux EM émis par la source EM verticale. Au moins un câble de traction est utilisé pour tirer la source EM et le récepteur EM à travers un volume d'eau.
