Abstract
A marine seismic acquisition system includes a frame that includes a central longitudinal axis and members that define orthogonal planes that intersect along the central longitudinal axis; a data interface operatively coupled to the frame; hydrophones operatively coupled to the frame; a buoyancy engine operatively coupled to the frame where the buoyancy engine includes at least one mechanism that controls buoyancy of at least the frame, the hydrophones and the buoyancy engine; and at least one inertial motion sensor operatively coupled to the frame that generates frame orientation data, where the hydrophones, the buoyancy engine and the at least one inertial motion sensor are operatively coupled to the data interface.

A marine seismic acquisition system, comprising:
- a frame that comprises a first set of members that defines a first plane and a second set of members that defines a second plane that is crosswise to the first plane and that intersects the first plane along a central longitudinal axis;
- a data interface coupled to the frame;
- a plurality of hydrophones mounted to the frame and the data interface;
- and
- a plurality of pressure spatial gradient sensors mounted to the frame and the data interface, wherein the plurality of pressure spatial gradient sensors are configured to measure pressure spatial gradients.
A method, comprising:
- controlling a marine seismic acquisition system to:
- acquire seismic data via a plurality of hydrophones and a plurality of pressure spatial gradient sensors mounted to a frame, wherein the frame comprises a first set of members that defines a first plane and a second set of members that defines a second plane that is crosswise to the first plane and that intersects the first plane along a central longitudinal axis, wherein the plurality of pressure spatial gradient sensors measure pressure spatial gradients;
- and
- transmit the seismic data to a data interface that is operatively coupled to one or more data storage devices.
A marine seismic acquisition system, comprising:
- a frame comprising a plurality of members arranged at least in first and second planes that are crosswise and intersect one another along a central longitudinal axis;
- a plurality of hydrophones mounted to the frame;
- and
- a plurality of pressure spatial gradient sensors mounted to the frame, wherein the plurality of pressure spatial gradient sensors are configured to measure pressure spatial gradients, wherein the plurality of pressure spatial gradient sensors and the plurality of hydrophones are collocated at a plurality of different positions.
