Abstract: The invention relates to a seismic system having an array of nodes, each capable of emitting and detecting seismic signals. The array of nodes is mounted on a mobile platform in a certain geometry and is configured to acquire subsurface data, and more particularly detect shallow buried objects, while being translated over a surface. Such a seismic system allows for high subsurface point redundancy by providing a large number of channels of data used to sum the energy at a point in the subsurface. In other aspects, the invention relates to methods for processing the acquired data to increase signal-to-noise ratio. In still other aspects, the invention relates to methods for imaging the data for visualization on a display.

Abstract: A system and method for reducing acoustic, wind or other background noise that may interfere with sensing of a seismic signal is provided. More specifically, a shield is provided to enclose a geophone and thereby protect it from harmful noise. The shield may comprise a rigid shell, a structural damping material, an acoustically absorptive material, and a compliant seal for coupling the shield to the ground or reference surface.
