ABSTRACT:
A plurality of sensor arrays are mounted in a streamer cable. The sensors within each array are distributed over an elongated two-dimensional vertical plane. The seismic streamer cable is so constructed that its vertical dimension is substantially greater than its width and the top portion is relatively more buoyant in the water than the bottom portion. Because of that configuration the streamer cable resists vertical strumming and, when the sensor arrays are used in the differential mode, there is no orientation uncertainty.
