ABSTRACT:
An electrode array for electric and magnetic measurements in a marine environment includes a first set of electrodes connected to a first cable, wherein the first set of electrodes and the first cable are configured to sink to a sea floor in the marine environment; a second set of electrodes connected to a second cable, wherein the second set of electrodes and the second cable are connected to the first cable and configured to float in the marine environment such that the second set of electrodes and the second cable maintain a distance from the sea floor when the first cable sits on the sea floor, and an instrument package connected to the first cable and the second cable, wherein the instrument package is configured to receive voltage signals measured by the first set of electrodes and the second set of electrodes.
