    摘要： The described invention relates to seismic acquisition means for use in shallow water marine environments, comprising: (a) a vessel (1) having at least one hull (25); (b) one or more shaker (13) and baseplate (12) assemblies affixed to the vessel by two or more rigid supporting elements (11) adapted to be capable of lowering said assemblies from the vessel hull to a shallow water bottom (14) and of raising said assemblies from the shallow water bottom to the hull; and, wherein each of said assemblies comprise one or more vibrator units mounted on a baseplate that is adapted to rest upon the shallow water bottom and to transmit vibratory signals from the vibrator units into said water bottom. The described invention provides a high-amplitude, broadband seismic signal, provides high data-production rates, couples energy directly into the earth and minimizes damage to the water bottom.

    摘要： A receiver consistent deconvolution operator models the damped oscillatory wavetrain that is related to geophone coupling to the water bottom. The operator is a best-fitting function that endeavors to describe the difference in coupling response between a well-coupled in-line geophone relative to an imperfectly-coupled cross-line geophone. The operator is applied to the cross-line signals to compensate the signals for the distortion due to imperfect cross-line ground coupling.

    摘要： A method and apparatus for seismic vibrator surveying which yields improved coupling of the vibrator (33) to the earth's surface with significantly reduced disruption of the earth's surface remaining after the vibrator is used. A preferred embodiment comprises a flat metal plate (32) with a flat earth-coupling layer (31) of neoprene bonded thereto which allows imparting of seismic energy into the earth directly through the surface of a paved roadway (34).
