Lenhardt, W K

A seismic data gathering system includes a seismic cable having a plurality of cable sections, each including a seismic detector and a pair of signal lines for carrying the seismic energy signals produced by the detector in response to seismic energy waves. A shunting resistance is located in each cable section with one end connected to one of the pair of signal lines and the other end connected through a mating connector to the other of the pair of signal lines in the next succeeding cable section so that a shunting resistance is added to the seismic cable each time a detector is added to the seismic cable. In this manner the electrical damping of each seismic detector remains constant when the seismic cable is coupled to a data acquisition unit regardless of the number of detectors included within the seismic cable.
