A marine electromagnetic survey system includes a power cable configured to couple to a power supply at one axial end, and to a head unit at the other end. The power supply includes a source of direct current which is coupled to the power cable. The head unit includes equipment configured to output a lower voltage at a higher current than the source of direct current. At least one electromagnetic antenna is coupled to the head unit and is configured to receive the output of the head unit equipment.
