Patent ID: 8098542

Claim:
A marine geophysical sensor streamer, comprising: a jacket extending along the length of the streamer; a least one strength member extending along the length of the streamer; a plurality of electromagnetic field sensors at spaced apart positions along the streamer; a plurality of seismic sensors disposed at spaced apart locations along the streamer, the seismic sensors including at least one particle motion responsive sensing device and at least one pressure responsive sensing device; and a signal processing module associated with each electromagnetic field sensor, the signal processing module including signal processing devices for at least one of storing and communicating measurements made by the associated electromagnetic field sensor, the modules each including an electric energy storage device associated with the signal processing devices such that the signal processing devices are operable without conducting electrical power along the streamer and a relay for closing a circuit to the energy storage device for recharging thereof, the relay configured to open conductor loops along the streamer created by electrical conductors used to supply electric power to the modules.
