Abstract

See full text

Retriever systems for marine geophysical survey cables. At least some of the illustrative embodiments are methods including causing a submerged sensor streamer to surface by flooding an intermediate chamber with water, the intermediate chamber defined within a cylinder of a housing coupled to the sensor streamer, the flooding of the intermediate chamber responsive to the sensor streamer reaching or exceeding a predetermined depth; and responsive to flooding the intermediate chamber moving a first piston within the cylinder; and thereby puncturing a seal of a compressed gas cylinder responsive to movement of the first piston, the puncturing makes the sensor streamer more positively buoyant.
