Abstract: A method for automatically propagating a voltage along a marine seismic streamer, the method including detecting, at an ith concentrator of the streamer, a first voltage applied at a first high-voltage rail HV1; detecting, at the ith concentrator of the streamer, a second voltage applied at a second high-voltage rail HV2, the first and second high-voltage rails extend over the entire streamer; checking a predetermined condition at a first local controller of the ith concentrator; and closing a first switch SW1, which propagates the first high-voltage rail HV1, when the predetermined condition is satisfied.

Abstract: The present disclosure provides a method and a system for acquiring seismic data of a four-component ocean bottom node (OBN). The method is implemented by the system, comprising controlling installations of a plurality of ocean bottom submerged buoys and a plurality of four-component OBN seismic data acquisition instruments and sending positioning signals and timing signals to the plurality of ocean bottom submerged buoys through armored opto-electronic composite cables. The method also includes obtaining real-time and uninterrupted water temperature data, pressure data, density data, and salt saturation data along the armored opto-electronic composite cables from the ocean surface to locations of the plurality of ocean bottom submerged buoys, and calculating real-time and three-dimensional data of waters of a whole measurement work area through interpolation. The method further includes performing real-time correction on a hydroacoustic velocity of each hydroacoustic propagation trajectory based on the location, the hydroacoustic propagation trajectory and the three-dimensional data of each acquisition instrument.

Abstract: Embodiments included herein are directed towards a marine seismic streamer. The seismic streamer may include an outer skin formed in longitudinally extending tubular shape, an inner surface of the outer skin defining an internal volume containing a gel substance. The seismic streamer may also include a plurality of micro-electro-mechanical (“MEMS”) sensors and plurality of hydrophones associated with the outer skin, wherein in the plurality of MEMS sensors are spaced non-uniformly in the seismic streamer along an axial direction of the streamer, such that not more than 100 MEMS sensors are located in the seismic streamer over a continuous 100 meter axial length of seismic streamer. The seismic streamer may further include an electronics system extending axially through an inside portion of the outer skin and a strength member core extending axially through an inside portion of the outer skin.
