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.
