Abstract: This disclosure is related to marine seismic sources, for example marine seismic sources known in the art as benders. Some embodiments of this disclosure use Lorentz forces to produce seismic energy. For example, magnets and wire coils may be attached to one or more plates of a marine seismic source, and the Lorentz interaction between them may cause deformation of the plates to produce seismic energy. Such marine seismic sources may be components of a marine seismic survey system, and may be used in a method of marine seismic surveying. Methods of making marine seismic sources are also disclosed.

Abstract: Techniques are disclosed relating to towing source elements and geophysical sensors through a body of water using one or more unmanned tow vessel. In some embodiments, a plurality of unmanned tow vessels are configured to tow one or more signal sources and/or one or more streamers. The plurality of unmanned tow vessels may, in some embodiments, traverse various sail paths along a surface of a body of water in order to acquire geophysical data relating to formations disposed below the bottom of the body of water.

Abstract: This disclosure is related to marine seismic sources, for example marine seismic sources known in the art as benders. Some embodiments of this disclosure use magnetic reluctance forces to produce seismic energy. For example, pole pieces may be attached to one or more plates of a marine seismic source, and a wire coil may induce an attractive force between the pole pieces to cause deformation of the plates to produce seismic energy. Such marine seismic sources may be components of a marine seismic survey system, and may be used in a method of marine seismic surveying. Methods of making marine seismic sources are also disclosed.

Abstract translation: 本公开涉及海洋地震源，例如本领域已知的作为弯曲机的海洋地震源。 本公开的一些实施例使用磁阻力来产生地震能量。 例如，极片可以附接到海洋地震源的一个或多个板，并且线圈可以在极片之间引起吸引力，从而引起板的变形以产生地震能量。 这种海洋地震源可以是海洋地震勘测系统的组成部分，可用于海洋地震勘测方法。 还公开了制作海洋地震源的方法。
