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) include first and second switches (48b and 48c), respectively. The 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 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: Remote seismic data acquisition unit for receiving seismic radio signals, having the capability of receiving both seismic data acquisition radio signals and GPS signals, uses a single antenna for receiving both types of signals, a signal splitter to separate the signals and a low noise amplifier to enhance the GPS signals. A GPS receiver/transmitter is incorporated within the housing for the seismic data acquisition system radio signal receiver.
