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.
