Abstract: Streamer section connector used as an electrode. A first streamer section includes a first outer surface that defines an interior volume, a first connector coupled to a first end of the first outer surface, and a first digitizer node. The digitizer node defines a first input port and second input port, the first digitizer node disposed within the interior volume of the first outer surface, and the first input port is electrically coupled to the first connector such that the portion of the first connector that is electrically conductive is a first electrode. The first digitizer node configured to measure a potential difference between the first electrode at a first potential and a second potential coupled to the second input port.

Abstract: A sensor streamer drag body system. At least some of the example embodiments include a system having a sensor streamer towable behind a vessel in a body of water, the sensor streamer defining a defining a distal end and a proximal end, the proximal end nearest the vessel. The system further includes a drag body coupled to the distal end of the sensor streamer, wherein the drag body remains submerged while the sensor streamer is deployed. The drag body includes an inertial navigation system. The inertial navigation system is configured to determine a position of the drag body, the drag body lacking an internal GPS.

Abstract: An apparatus. At least some illustrative embodiments are an apparatus comprising a sensor streamer. The sensor streamer includes at least one seismic streamer section and a first electrode adapter removably attached to the at least one seismic streamer section. The first electrode adapter includes a first electrode, wherein the first electrode is configured to couple to electrical circuitry configured to measure a potential difference between the first electrode at a first potential and a second potential. The conducting member forms a reference potential, wherein the conducting member is floating. The at least one seismic streamer section is without electromagnetic field-sensing components.
