Abstract: An improved bottom cable for a seismic marine data acquisition system (10). The bottom cable (30) includes a cable section (30b) having a bus (48). The cable, along with the cable section and bus, are used to electrically connect a master control unit (40) to first and second modules (32b and 32c), respectively. The bus (48) includes first and second switches (48b and 48c), respectively, located near opposite ends of the bus. In this way, if a leak (R1) occurs in the bus, the first and second switches can be opened, thereby electrically isolating the bus and stopping the leak.

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.

Abstract: A seismic ocean bottom posi-tioning device includes a series of seismic stations (14) spaced apart at a predetermined interval along a ca-ble. Each station (14) includes a hydrophone, a motion sensing device such as a geophone (22) and an acous-tic positioning circuit (24). A pream-plifier is coupled to a seismic channel. The hydrophone (20) is also coupled to the seismic channel. An acoustic chan-nel is also coupled to the preamplifier and coupled to the hydrophone .

Abstract: A method and apparatus are provided for matching the responses of hydrophones (22) to the response of geophones (24) and significantly reducing response variations between hydrophones caused by inherent characteristics. The method includes the steps of determining a capacitance (66) for each of the hydrophones (22) in an operating environment, configuring a filter (36) based on the capacitance (66), and modifying a response of a channel of the hydrophone (22) using the filter (36). The apparatus includes an acquisition unit (20) having a geophone (24) and a hydrophone (22), a recording unit (30), a processing unit (31) and a filter (36) for correcting for variation between hydrophones (22) and changing a first order low frequency response of the hydrophone (22) to appear like a second order response like that of the geophone (24).
