Abstract: An apparatus for maintaining at a predetermined depth a tow cable, such as that of a seismic streamer, being towed by a vessel, the apparatus having one or more depth controller devices attached to the cable at spaced intervals therealong and a remote command transmitter on the tow vessel for transmitting commands to the depth controller devices, the depth controller devices having a mechanism responsive to deviations between the commanded depth of the cable and its actual depth for moving diving planes of the controller devices to cause the controller devices to move to the commanded depth as the cable is towed along by the vessel.

Abstract: A marine hydrophone for producing electrical signals responsive to sound pressure waves in water, and especially adapted for use in towed seismic streamers. The hydrophone includes an annular piezoelectric ring with electroded inner and outer surfaces and a pair of thin circular diaphragms covering the opposite ends of the ring. The diaphragm portions within the inner surface of the ring are permanently formed inwardly toward each other. An assembly of a pair of such hydrophones supported by resilient rings on opposite ends of an axially elongated support cylinder mounted within an cylindrical enclosure having perforated end caps and mounted by a resilient tube between streamer spaces is also disclosed.
