Abstract: A method of and an apparatus for mounting seismic vibration sensors to a cable designed for use offshore, such that the sensors are optimally coupled to the ocean floor through all cylindrical rotations when the cable has reached the bottom after being slipped over the transom of a deployment vessel. Said coupling is accomplished without the use of a sub-surface robotic vessel to force the sensors into a particular orientation. The housing for the sensors is adapted to endure and minimize the impact on the host cable of the mechanical extremes the system is subjected to in the process of the conventional deployment and retrieval methods.
