ACOUSTIC POSITIONING OF SEISMIC OCEAN BOTTOM CABLE

摘要

A seismic ocean bottom positioning device includes a series of seismic stations (14) spaced apart at a predetermined interval along a cable. Each station (14) includes a hydrophone, a motion sensing device such as a geophone (22) and an acoustic positioning circuit (24). A preamplifier is coupled to a seismic channel. The hydrophone (20) is also coupled to the seismic channel. An acoustic channel is also coupled to the preamplifier and coupled to the hydrophone.
