Abstract: A preferred seismic survey system includes a cable having a sensor unit. The sensor unit includes sensors for detecting acoustical energy (e.g., shear and/or pressure waves) and is disposed in a decoupling device that substantially acoustically uncouples the sensor unit from the cable. One preferred decoupling device includes relatively flexible tension members that isolate the sensor unit from acoustical-energy related movement of the cable. A fastening member, which is optionally formed of vibration absorbing material, affixes the sensor unit to the flexible member. Optionally, a spacer adjusts the resonant frequency of the tension member and a resilient tube encloses the decoupling device. One preferred seismic survey method includes connecting the sensor unit to a cable with a decoupling device that substantially acoustically uncouples the sensor unit from the cable; and positioning a sensor unit on a seabed such that the sensor unit is acoustically coupled to the seabed.
