Abstract
A seismic ocean bottom positioning device include a series of seismic stations spaced apart at a predetermined interval along a cable. Each station includes a hydrophone, a motion sensing device such as a geophone and an acoustic positioning circuit. A preamplifier is coupled to a seismic channel. The hydrophone is also coupled to the seismic channel. An acoustic channel is also coupled to the preamplifier and coupled to the hydrophone.
