Publikováno v: Energies, Vol 15, Iss 4, p 1272 (2022)

We introduce a new synthetic marine model for 3D controlled-source electromagnetic method (CSEM) surveys. The proposed model includes relevant features for the electromagnetic geophysical community such as large conductivity contrast with vertical tr
