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: 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.
