We present results of tests conducted using a prototype EM streamer section in a wave tank to investigate sources of noise associated with towing an EM streamer. Flow was run at velocities of 0-1.5m/s parallel to the streamer suspended 1m below the water surface. Waves were also generated at different heights, frequencies and in different directions relative to the streamer. Motion capture cameras were used to record the motion of the streamer at 13 points. The results show conclusively that the dominant electric field noise in a the streamer is due to the motion of the streamer within the earth's magnetic field.
