To determine the feasibility of the MTER method we examined arrays consisting of a pole electrical dipole (PED), vertical electrical dipole (VED) and horizontal electrical dipole (HED). The VED array showed a maximum difference in electric fields of 36% and 105% in the resistive and conductive models, respectively, while the PED and HED arrays yielded worse results of around 13% to 19%, respectively. The VED array showed a higher difference in electric fields than both the HED and PED arrays in the two models. Therefore, we suggest that a VED array with a large electrical current would be most conducive leading to the discovery of such minerals during MTER surveys.en-USDC resistivity survey; Forward modeling; Marine towed electrical resistivity; Methane hydrates; Sulfide deposits[SDGs]SDG14electric field; electrical method; electrical resistivity; gas hydrate; geophysical array; marine sediment; methane; numerical model; sulfide groupjournal article10.3319/TAO.2011.02.16.01(T)http://ntur.lib.ntu.edu.tw/bitstream/246246/240478/-1/76.pdf
