Abstract
A streamer-cable assembly is provided having a tubular outer jacket enclosing an open-cell foam case providing an axial hole for retaining a plurality of pressure sensors. A plurality of off-axial holes provide passages for the transmission bundle. Longitudinal channels along the exterior receive stress members which provide longitudinal rigidity to the streamer. Cable noise associated with cable jerk, and cable-whip or vibration is radically reduced by the foam core and rigid stress members.
