<p>A seismic streamer for reception of reflection signals during seismic surveys at sea has an external, tubular cover (1) of a flexible plastics material. In order to reduce reception of noise in the streamer, the external cover (1) is constructed with grooves (3) extending longitudinally of the cable, preferably spaced regularly around the entire periphery of the cover (1). <IMAGE></p> |
