Disclosed are methods and systems that include a multiple-tube electrode assembly. An embodiment discloses an electrode assembly, comprising: a carrier body comprising an elongated support; and electrically conducting surfaces longitudinally spaced along the carrier body, wherein the electrically conducting surfaces are electrically coupled in parallel.

Electrode assembly for marine electromagnetic geophysical survey sources

A marine electromagnetic geophysical survey transducer cable includes a tow cable configured to couple to a tow vessel. A first electrode cable is coupled at a forward end to the tow cable. A second electrode cable is disposed aft of the first electrode cable and configured to indirectly couple to the tow vessel. At least one of the first and second electrode cables includes a cable core comprising a first core material having a first density selected to provide the transducer cable with a selected overall density, and at least one layer of electrically conductive strands disposed exterior to the cable core.
