Abstract : The vane-shear devices currently in use exhibit inherent problems and shortcomings associated with their design. The PGS Vane-Shear Apparatus is designed to eliminate these shortcomings. The unique features of the device include: (1) Ability to be used in the laboratory or on board ship. (2) A single unit which is easily calibrated and capable of measuring torque over the entire range commonly encountered in marine sediments. (3) A torque transducer which is insensitive to temperature changes and orientation. (4) Ability to determine shear strength prior to cutting the core liner, thus reducing the disturbance to the sediment caused by cutting and handling. (Author)
